Accompanying drawing explanation
Fig. 1 is a kind of electrical block diagram protecting order panel computer according to a first embodiment of the present invention;
Fig. 2 is a kind of electrical block diagram protecting order panel computer according to a second embodiment of the present invention.
Embodiment
First refer to Fig. 1, Fig. 1 is a kind of electrical block diagram protecting order panel computer according to a first embodiment of the present invention.As shown in Fig. 1, one is according to a first embodiment of the present invention protected order panel computer and is comprised: control chip 101, and for obtaining ambient light compensation trigger pip, and environmentally light compensates trigger pip generation control signal; Ambient light compensation module 102, luminous under control of the control signal, to compensate panel computer screen (not illustrating) surround lighting around.Wherein, control chip 101 can be preferably the baseband processing chip in mobile phone, but, also can choose the respective chip with controlling functions according to actual needs.
Panel computer comprises backlight module 103 further, backlight module 103 is arranged at the below of panel computer screen, to provide backlight to panel computer screen, control chip 101 is after acquisition ambient light compensation trigger pip, turn down the luminosity of backlight module 103 further, the light that panel computer screen is sent and the contrast of surround lighting reduce further.
Please continue see Fig. 1, panel computer also comprises button 104, user push button 104 time, this button 104 can produce ambient light compensation trigger pip to control chip 101, control chip 101 environmentally light compensates trigger pip generation control signal, and control signal is sent to ambient light compensation module 102, and ambient light compensation module 102 can be luminous under control of the control signal, to compensate the surround lighting of panel computer screen periphery.
It should be noted that, above-mentioned button 104 can be arranged on the side of panel computer, when user thinks that light more secretly needs to open ambient light compensation, as long as push button 104, button 104 sends ambient light compensation trigger pip to control chip 101 after being pressed, ambient light compensation module 102 is opened by control chip 101, to carry out ambient light compensation.And, except using the mode of button 104, the present invention also can produce ambient light compensation trigger pip by other modes, for example, luminance sensor can be utilized to respond to current environment brightness, and be sent to control chip 101 and analyze, if when control chip 101 determines current environment brightness lower than a specific threshold, then produce ambient light compensation trigger pip, and environmentally light compensation trigger pip checks and accepts control signal further, wherein, above-mentioned threshold value can add up gained by many experiments.
Refer to Fig. 2, Fig. 2 is the electrical block diagram of panel computer according to a second embodiment of the present invention, compared with the first embodiment, has been described in further detail the circuit structure of ambient light compensation module 202 in this enforcement.
As shown in Figure 2, ambient light compensation module 202 comprises: multiple light emitting diode 205, 206, 207, 208 and controlled switch 209, wherein, multiple light emitting diode 205, 206, 207, 208 are arranged in parallel, and its positive pole is connected with panel computer power supply 210, first end 2091 and multiple light emitting diode 205 of controlled switch 209, 206, 207, the negative pole of 208 connects, second end 2092 is connected with control chip, with reception control signal, 3rd end 2093 ground connection, first end 2091 and the 3rd end 2093 conducting under control of the control signal.
It should be noted that for convenience of explanation, in Fig. 2, only show 4 light emitting diodes, but in actual applications, its concrete quantity also does concrete restriction, but chooses according to actual needs.
In a preferred embodiment of the invention, ambient light compensation module 202 can comprise multiple current-limiting resistance 211,212,213,214 further, current-limiting resistance is arranged in series with light emitting diode respectively, to limit the size of current flowing through light emitting diode respectively, thus ensure light emitting diode normal luminous.
And in other embodiments of the present invention, also power supply can be provided to by the VBAT port of control chip 201 positive pole that multiple light emitting diodes 205,206,207,208 are provided.In addition, the positive pole of multiple light emitting diode 205,206,207,208 also can directly be connected with the cathode output end of panel computer battery or the power output end of power management chip, and the present invention does not do concrete restriction to it.And multiple light emitting diode 205,206,207,208 is preferably disposed on the back side of panel computer, the light sent to avoid it as far as possible shines directly into the eyes of user, and damages the glasses of user.
In a preferred embodiment of the invention, controlled switch 209 can be preferably NMOS pipe, PMOS certainly also can be adopted according to actual needs to manage or relay realization.
When controlled switch 209 is NMOS tube, control chip 201 inputs to the grid of NMOS tube using high level as Continuity signal, make source electrode and the drain electrode conducting of NMOS tube, multiple light emitting diode 205,206,207,208 is luminous, thus carries out ambient brightness compensation.And when not needing to carry out luminance compensation, control chip 201 input low level, to the grid of NMOS pipe, makes the source electrode of NMOS tube and drain electrode disconnect, multiple light emitting diode 205,206,207,208 stops luminous.
In addition, the port that control chip 201 is connected with the grid of NMOS pipe preferably adopts universal input and output port (GPIO, General Purpose Input Output), if universal input and output port is not the drop-down port of acquiescence, then need to arrange a pull down resistor (as shown in Figure 2) between the source electrode and grid of NMOS tube, remain on low level input state to make the grid of universal input and output port NMOS pipe when output low level.
Therefore; by above technical scheme, disclosed one is protected order panel computer and is provided surround lighting by ambient light compensation module, thus the light that panel computer screen is sent can not be too concentrated; the brightness of local can not be too high, the eyes of people served to the effect of protection.
These are only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize instructions of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
