DETAILED DESCRIPTION

The present invention relates generally to a computing or portable device. The device includes but not limited to cellular phone, PDA (personal digital assistant), smart phone, notebook, digital still camera, digital video camera, medium player (MP3, MP4), GPS and the equivalent thereof.
FIG. 1 is a diagram illustrating main components of a portable communication device using a panel with emitters and transparent substrate according to an embodiment of the present invention. The embodiment, as shown in FIG. 1 and FIG. 2, the device 20 includes a RF (Radio Frequency) module 190 coupled to a control unit 100. As know in the art, the RF module 190 includes antenna. This antenna is connected to a transceiver, which is used to receive and transmit signal. AS known, the RF module 190 further includes CODEC, DSP and A/D converter as well. Due to the RF module is not the feature of the present invention, therefore, the detailed description is omitted. Other major components between device 10 and 20 are similar, therefore, the same reference numbers refer to similar component, however, the version, grade and performance maybe different. The present invention includes a central control IC 100, an input and output (I/O) unit 150, OS 145, hybrid memory 165, the device 10 or 20 may includes other memory 155 such as ROM, RAM and FLASH memory. The RF module may perform the function of signal transmitting and receiving, frequency synthesizing, base-band processing and digital signal processing. If the portable device is cellular, SIM card hardware interface is provided for receiving a SIM card. Finally, the signal is send to the final actuators, i.e. a loudspeaker and a microphone 195 or I/O 150.
The present invention further includes a wireless transmission/receiving module 220 coupled to the control IC (control unit) 100. The transmission/receiving module is compatible with blue-tooth, home-RF, 802.11x, WiFi, WiMAX standard or their higher version. The transmission domain (the air) by nature is not secured and therefore encryption maybe essential in the wireless transport networks. In one embodiment, pair-wise encryption/decryption between every neighboring wireless network device of a wireless transport network is well-known in the art. A data frame that leaves from one wireless device from one end of a wireless transport network to the other end of the same network might need several encryptions and decryptions before it reaches its final destination. A mini projection module 230 maybe incorporated into the portable device, the mini projection module 230 may refer to the co-pending application Ser. No. 11/734,175, filed by the same inventor of the application.
Optionally, the present invention also provides a hard disk drive incorporated with a Flash memory within one single unit, as shown in FIG. 3 to have the benefits of both. The hard disk drive includes a control unit 400 coupled to a magnetic disk module having spindle driver, reading/writing head mechanism and so on. This is well-known in the art, and the description is omitted. A flash controller 440 is coupled to the control unit 400 and a nonvolatile memory 430 is coupled to the flash controller 440. An application 450 is coupled to the control unit to execute the instruction. The hybrid hard disc drive incorporates the flash memory into the device to yield the benefit of high-speed access and low power consumption. The hard disk drive maybe incorporated into portable media player, cellular, notebook or PDA. A controller 440 is connected to the flash memory 430 to operate the mode under instruction or command. The operation mode includes read mode, write mode, erase mode, and programming mode. Further, the controller 440 maybe integrated into the control unit 400 under the knowledge and technology of integrated circuits. An embedded system 470 is optionally stored in the erasable/programmable storage medium (flash, ROM or hard disk). It could be an application, software or a list of computer-executable instructions. Alternatively, the ROM 480 may be embedded in the control unit. The data coded in the ROM will not be erased by the user. The embedded system 470 could be provided for a computer or device to execute predetermined function such as operating some application, booting the device, auto backup or auto-run file. In general, after a device is power on, basic input/output system will perform a boot sequence before invoking the OS. Basic input/output system is set in the ROM. The programmer or instruction can be set in the embedded system to determine what type of data will be stored into what type of storage (flash or hard disk). It could be used for different type of volatile memory having NOR device and NAND device (FIG. 4). A hybrid memory scheme may refer to the above co-pending application filed by the identical inventor of the application, entitled “Monitoring System with a Wireless Transmitting/Receiving Module”. The co-pending application is incorporated herein for reference. Under such configuration, the computing device, for example, personal computer, notebook, may omit the hard disc drive. The scheme uses NOR device to act and replace the role of hard disc to store operation system and yield the benefit of high speed operation and low power consumption, while the data is stored in the NAND device. The operation speed will be higher than the one employing hard disc. In one embodiment, the embedded system is coupled to the control unit to determine or assign the duty of the magnetic disk module 420 and the nonvolatile memory 430. The flash benefits high speed performance, low power consumption while hard disk drive yields lower cost and high capacity. The storage architecture refers to Complementary Storage Device (CSD). The CSD has the benefits of the both type of memory. The manufacture may reduce the cost and increase the performance by incorporating the two kinds of memory with an optimized memory ratio between the flash memory and the magnetic memory.
Almost all conventional devices include an antenna located within the portable device, the signal receiving performance is poor due to EM shielding effect generated by the shield, circuits, circuit board and other components. If the antenna to the signal is “transparency”, the performance will be improved. Therefore, in another aspect of the present invention is to provide an antenna located corresponding to a substantially transparent display panel to minimize the EM shielding effect, thereby improving signal receiving/transmitting performance. Preferably, at least one transparent antenna is attached on the substantially transparent display panel to minimize the EM shielding effect. As seen in FIG. 1 and FIG. 2, a substrate 400 is provided and transparent electrodes 420 are formed on the glass substrate 400. The substrate 400 could be silicon, glass, quartz or the like. The embodiment of the present invention is shown in FIG. 5, it is a cross-sectional view of the field emission device according to the present invention. As seen in FIG. 5, the field emission devices array 4000 includes a transparent substrate 400 and transparent electrodes 420 are formed on the transparent glass substrate 400. The transparent electrodes 420 may be made of indium tin oxide (ITO) and may be used as the emitter electrodes. Stacked gate 410 that cover a portion of the transparent electrodes 420 are formed on the transparent glass substrate 400. Emitters 460 that emit electrons are formed on a portion of the transparent electrode 420. Each stacked gate 410 includes a mask layer 440 that covers a portion of the transparent electrodes, and is formed by UV photolithograph mask. The mask layer 440 is preferably transparent to visible light, but opaque to ultra violet rays and can be made of an amorphous silicon layer. The silicon layer will be transparent when the thickness is thin enough. A stacked gate 410 structure includes first insulating layer/a gate electrode/a second insulating layer/focus gate electrode, sequentially formed over the substrate. The gate insulating layer is preferably a silicon oxide thin film and the gate electrode is made of chrome. The gate electrode is used for extracting an electron beam from the emitter. The focus gate electrode performs as a collector for collecting electrons emitted from emitter so that the electrons can reach a fluorescent film 480 disposed above the emitter 460. If the filed emitting device is used for display, the substrate can be silicon or transparent substrate. Referring to FIG. 5, a front panel (substrate) 450 is disposed upward and above the stacked gate. A variety of visual images are displayed on the front panel 450. A fluorescent film 480 is attached to a bottom surface of the front panel 450 that faces the stacked gate and a direct current voltage is applied to the fluorescent film 480 to emit color for display. The fluorescent substance may emit color light by mixing the emitted light if the thin film with R, G, B fluorescent substances when the fluorescent film 480 is hit by the electron emitted from the emitter. Preferably, the fluorescent substances emit red, green, and blue visible light when excited by the electron beam is evenly distributed on the fluorescent film 480. Any color including white color can be mixed by the R, G, B fluorescent substances. White color is provided by white fluorescent substances. The spacer separating the front panel 450 from the stacked gate is a black matrix layer and is not shown for convenience. Due to the thin film display if formed with thinner thick and the power consumption is lower than LCD, the present invention may provide smaller size, lighter weight device. The life time of battery may last longer. The field emission device does not require complicated, power-consuming back lights and filters which are necessary for LCD. Moreover, the device does not require large arrays of thin film transistors, and thus, a major source of high cost and yield problems for active matrix LCDs is eliminated. The video image resolution of the display and the local brightness can be improved by using a focus grid to collimate electrons drawn from the microtips. Preferably, the emitter includes a carbon nanotube emitter to further reducing the device size. The conductive carbon with nano-scale may reduce the width of the conductive electrode, thereby reducing the scale of electrode and increasing the resolution without down grade the performance. The CNT and the conductive polymer have better conductivity than prior art bulk silicon even minimizing the size of the structure. It may provide the local illumination and local brightness over the prior art. The CNT and the conductive polymer have better conductivity than prior art bulk silicon even minimizing the size of the structure. It may improve the electronic transmitting rate with transparent characteristic when it is formed with thinner thickness. The carbon nanotube emitter has smaller and sharper tip, the electronics may concentrate the tips by the corona discharge effect, thereby improving the electronic emitting performance. If a charged object has a sharp point, the air around that point will be at a much higher gradient than elsewhere. Air near the electrode can become ionized (partially conductive). When the air near the point becomes conductive, it has the effect of increasing the apparent size of the conductor. Further, the display may omit the liquid crystal material. Further, the field emission display does not require the S/D regions which are required by TFT for LCD. If LCD is used, the above field emission devices with CNTs may be employed to emit illumination to act as back light for the LCD needs. No matter the display is FED display or LCD display, the carbon nanotube (CNT) field emitter may improve video images for display and is operated with locally controllable luminance and local dimming, local brightening. As known in the art, the LC (liquid crystals) module includes a display unit having a first (rear) polarizer, a first transparent (such as glass) substrate and a first transparent electrode. A transistor array is formed over the first transparent electrode. LC (liquid crystals) is formed over the transistor. A second (front) transparent electrode is formed over the LC and a second (front) transparent substrate and color filter are subsequently formed over the LC. A protection glass and second (front) polarizer are formed over the color filter. The transistor array is formed over the substrate and the gate of the transistor is patterned and isolation layer is formed over the gate.
In another embodiment, the display is shown in FIG. 6. The display includes a transparent electrode 510 on a transparent substrate 500. A fluorescent film or power 520 is attached to an upper surface of the lower transparent electrode 510. Preferably, the fluorescent substance emits color light. The present invention includes three such devices that separately display image in red components, green components, and blue component. Each irradiates single color light. Different powder will emit different color. An upper transparent electrode 530 is formed on the fluorescent film or power 520. A second transparent substrate 540 is formed on the transparent electrode 540. A bias is applied on the electrodes to inject hole and electron, thereby exciting the fluorescent substances by the combination of the electron and hole to emit red, green, or blue visible light depending on the compound of the fluorescent substances. The elements may refer to ELP.
In another embodiment, the wireless data transferring module 220 includes dual mode module. Please refer to FIG. 7, in one case, the wireless data transferring module 220 includes a first and second wireless module 600 a and 600 b for wireless transmission. The dual modules 600 a and 600 b are coupled to a management unit 600 to manage the dual modules according to the policy set in a policy engine 610. For example, the policy in the policy engine 610 includes at least the transmission priority policy to determine which module will be the default module to receive/transmit data. It also includes the switching condition for switching there between. For example, the signal strength is one of the facts for switch condition. It also allows the user to set or alter the condition via user interface. The first and second wireless module maybe one of the following module: blue-tooth, 802.11x, WiFi, WiMAX, 3G standard or their higher (update) version. Preferably, the first wireless module is WiFi and the second wireless module is WiMax. The present invention may yield the benefits of both. For example, the access range of WiFi is shorter than WiMax, but it consumes lower power. If within the office area, the AP for WiFi may be employed to prevent others outside the office from accessing the server of the office. In another aspect, if the user would like to access or remote control a terminal device located at several miles away, the WiMax is chosen. The WiFi benefits security, low power consumption while WiMax yields long range and high bandwidth. The module architecture refers to dual wireless module (DWM). The DWM has the benefits of the both type of module. The first wireless module is compatible to a first communication protocol, while the second one is compatible to a second communication protocol. The manufacture may increase the performance by incorporating the two kind of wireless module memory with an optimized configuration. The protocol maybe adapted to wireless local area network or wireless mediate area network.
From above, the thick and complicated LCD panel is removed, thereby reducing the thickness of the portable device, and a lot of elements such as color filter, LC material, back light module, are also skipped from the present invention. Furthermore, due to the substrate 400, 450 could be formed by glass, quartz or the like, therefore, the present invention may offer unexpected and funny visual effect. Under the sleep mode or off state of the device, the panel is substantial transparent, while the device is not operation or standby, or at the sleep mode, the panel may act as digital photo album due to the panel is transparent. Further, the user may alter the color, image pattern displayed on the panel when the device is in the sleep mode or off-state. The user may determine the pattern and image for the panel cover. Furthermore, a transparent antenna may be attached on the transparent panel to provide better signal transmission due to EM shield effect of the antenna will be minimized while the antenna is not set within the device. In this case, the antenna is composed by a material includes oxide containing metal or alloy, wherein the metal is preferable to select one or more metals from Au, Zn, Ag, Pd, Pt, Rh, Ru, Cu, Fe, Ni, Co, Sn, Ti, In, Al, Ta, Ga, Ge and Sb. Some of the transparent material includes oxide containing Zn with Al2O3 doped therein.
Further, referring to FIG. 8, the wireless transferring module 220 and hybrid memory maybe employed by a digital camera or digital video camera. Preferably, the device includes a main body having a control IC 802; a display 804 formed on the main body and coupled to the control IC 802; an image capture element 806 formed within the main body and coupled to the control IC 802; the hybrid memory 808 is coupled to the processor; a lens mechanism 810 is formed on the main body, coupled to the control IC 802 and corresponding to the image capture element 806; the wireless transferring module is coupled to the processor for data transferring with external device.
If the present invention is employed for medium player such as MP3 player, MP4 player, the player includes an analog/digital (A/D) converter for converting analog audio signals into digital audio signals. The analog audio signals can come from an audio source coupled to player. A digital signal processor (DSP) or an audio and/or video driving module, for instance MP3, MP4 codec, are coupled to A/D converter to receive the digital audio signals. In one embodiment, MP3 or MP4 codec executes a firmware that includes a MPEG audio layer (e.g., MP3, MP2, or both) codec or video codec (e.g., MP4), and DSP executes a firmware that includes a different type of audio codec (e.g., WMA, ACC, or both). In one embodiment, the firmware for DSP also includes a video codec for encoding and decoding videos (e.g., MPEG-4 V1/V2/V3, DivX 3.11/4.0/5.0, Xvid, AVI/ASF, or any combination thereof). MP3 (or MP4) codec and DSP are coupled to a nonvolatile memory that stores the compressed audio data. The user can select an audio file from nonvolatile memory. DSP are coupled to an audio processor, which processes the digital audio signals according to default settings or user instructions. Audio processor is coupled to a digital/analog (D/A) converter, which converts the digital audio signals into analog audio signals for the user.
The present invention also provides a user control module to control the cursor without mouse or touchpad. A computing device comprises a display and a detecting device for detecting motion of a user. A movement information generating device is in responsive to the detection to generate an output signal, thereby generating movement information. A cursor control module is in responsive to the movement information to drive a cursor on the display corresponding to the movement information. Referring now to the drawings 1-2 and 9, there is shown in schematic form the basic components of the control module 185 incorporating the eye or face control module according to a preferred embodiment of the invention. The present invention includes a step of detecting the motion of a user. Preferably, the portion for detection could be eye, face or the like. The eye detection will be introduced as one of the examples to illustrate the features of present invention. The subject's face or eye is positioned relative to a sensor so that initially the subject's gaze is aligned along center line toward a pupil stimulus and fixation target. The eye control module 185 includes sensor and IC to detect eye motion and generate a control signal. The face motion could be used to practice the present invention. A detecting source 18505 is provided, the pupil of the eye(s) is (are) illuminated by the light source 18505, for example, an infrared ray (IR) or light emitting diode (LED). Preferably, dual source LED is used to project two spatially separated spots at the subject's pupil. The dual source LED is constructed by placing two LED side by side on the panel 400 a of the portable device. Back light from the subject's eye is detected by a sensor 18510 directly or via other optical mirror or lens. Another method is to detect the user face motion or image by the sensor. The sensor 18510 could be optical sensor such as CMOS sensor or CCD. The outputs from the sensor 18510 are input to a processor or control integrated circuits 18515 to generate a control signal to a cursor control module 18520 for controlling a cursor on the display or panel. Eye detection method may refer to U.S. Pat. Nos. 7,130,447 and 5,943,754, both are assigned to The Boeing Company (Chicago, Ill.); U.S. Pat. No. 5,670,613, assigned to Pulse Medical Instruments, Inc. (Rockville, Md.). U.S. Pat. No. 5,422,690 discloses eye recognition and blink detection system. Preferably, the detecting source or the like scans the position of the pupil of eye(s). In this process, the pupil is illuminated by a light source, so that the geometric form of the pupil can be portrayed clearly on the sensor. Alternatively, the image (face) change of the user could be detected by the present invention. By means of image processing, the pupil position information is evaluated and to determine where the eye in the display is looking. The control signal may drive the cursor to the position where the eyes are looking through cursor control module 18520. A buttons-image (or button-icons) may be generated along with the cursor by an image generator 18525. In one case, the image generator 18525 maybe a touch screen module which may generate touch screen image via well-known touch screen technology, in the manner, the user may “click on” the virtual bottom to input a command by means of “clicking” the touch screen. Alternatively, the click signal may be input from input interface 18540 such as (the right and left buttons of) the keypad, vocal control module through microphone, eye motion through the sensor 18510. In the case of vocal control module, another software/hardware maybe necessary to process the steps of object selection through voice recognition hardware and/or software. For example, the action of close left eye refers to click left button while the action of close right eye refers to click right button. If both eyes close, it may refer to select one item from a list. The above default function may be practiced by a program and software. It should be understood by persons skilled in the art, the foregoing preferred embodiment of the present invention is illustrative of the present invention rather than limiting the present invention. Modification will now suggest itself to those skilled in the art. Under the method disclosed by the present invention, the user may move the cursor automatically without the mouse. Similarly, the control signal may be used to drive the scroll bar moving upwardly or downwardly without clicking the bar while reading document displayed on the screen, as shown in FIG. 11. Thus, the control signal generated by IC will be fed into the scroll bar control module 18550 to drive the scroll bar 18555 on the display moving upwardly or downwardly without the mouse or keypad. An eye controllable screen pointer is provided. The eye tracking signals are performed in a calculation by a processing means residing in a processor or integrated circuits to produce a cursor on the screen. Alternatively, the control signal generated by the IC 18515 will be fed into an application software 18560 to drive a function module 18570 (such as microphone, camera, mini projection module) on the display without the mouse or keypad, as shown in FIG. 12.
The sensor is electrically coupled to the controller (IC) 18515 via line. In a preferred embodiment, input controller 18515 comprises a semiconductor integrated circuit or chip configured to receive, interpret and process electrical signals, and to provide output electrical signals. Output signals from IC 18515 comprise signals indicative of movement of eye in a direction corresponding to the direction of actual cursor movement on the display intended by the user. The present embodiment takes into account a possible “dragging” situation that the user may be faced with. On occasion, some users have a need to “drag” an icon or other object from one area of the screen to another. On some computers, to accomplish this, the user must hold down the left click button and control the pointing device at the same time. If a touchpad is being used as the pointing device, and the object must a dragged a long distance across the screen, sometimes the user's finger may reach the edge of the touchpad. This situation is easily handled by the present invention. In such a situation, the controller may send the command (e.g. “click left mouse button”, while dragging) repeatedly until the user's finger leaves a keyboard key (stops pressing a key). This permits dragging to be performed even after the user's finger leaves the touchpad. U.S. Pat. No. 7,165,225, assigned to Microsoft Corporation (Redmond, Wash.) disclosed “Methods and systems for cursor tracking in a multilevel GUI hierarchy”. U.S. Pat. No. 7,095,447, assigned to Samsung Electronics Co., Ltd. (Kyonggi-do, KR) disclosed “OSD (on screen display) cursor display method and cursor image display apparatus”. U.S. Pat. No. 7,137,068, assigned to Microsoft Corporation (Redmond, Wash.) disclosed “Apparatus and method for automatically positioning a cursor on a control”. U.S. Pat. No. 6,774,886, assigned to Matsushita Electric Industrial Co., Ltd. (Osaka, JP) disclosed “Display system, cursor position indication method, and recording medium”.
