Compared with the conventional image tube TV, it has the advantage of miniaturization, and it stands for the high-tech image. However, due to the power-saving regulations, the boot process of the LCD TV can be divided into two types: cold boot and hot boot. When the LCD TV is turned off by an infrared remote control, most of the components of the LCD TV are powered off. At this time, only a few components are powered, and the microprocessor with the infrared receiving device is powered. When the user turns on the LCD TV, the micro-wrap device with the infrared receiving device can immediately process the booting command, and transmits a power-on management device to the power-on management device to activate the LCD TV. . This boot process is a hot boot mode. When Putian users use an AC power switch to turn off the LCD TV, the liquid = all components on the TV are powered off. When the user presses the power switch again to turn on the liquid crystal television, the microprocessor performs initial initialization and then performs initialization on the peripheral components, and α turns on the liquid crystal television. This 幵' machine process is a cold boot mode. Fig. 1 is a conventional liquid crystal television starting flow 5 1330038. In step S1I0, the AC power switch is pressed to power the liquid crystal. In step S120, a microprocessor of the liquid crystal television is first initialized: In step S13(), the microprocessor executes the program and performs initialization on the peripheral 70 pieces. In step S140, the microprocessor executes a program 5 to turn on the light-emitting diode (LED) e on the LCD TV work panel in step S150, which enters a standby state...m〇de). In step S160, the 3H microprocessor checks whether the command from the infrared remote control machine or the button from the LCD TV work panel, if any, will open the display panel of the LCD TV. The power source 1〇 (step S17〇). If not, the process returns to step S160. However, it takes a lot of time to perform initialization on the peripheral components in step 513. Since the LED representing the power source is not π after the peripheral components are initialized, the user often mistakes the LCD TV for malfunction.

The right to enable the operation of the ❹(4) wire when the television is turned on. 6 1330038 Another object of the present invention is to provide a The method of quickly turning on the TV, avoiding the problem that the LCD TV's AC power switch and related parts are easily damaged. According to a feature of the present invention, a method for quickly turning on a television set is provided, which comprises the steps of: (A) turning on an AC power source to provide power to the television set; and (B) initializing a micro-processing of the television set. , which initializes and sets the working mode of the microprocessor; (c) tests one of the memories used by the microprocessor; (D) turns on a light emitting diode (LED); enters a standby mode; F) It is judged whether there is an input of the power-on command, and if it is determined that there is no input of the power-on command, the process proceeds to step (F). [Embodiment] The method for quickly starting up the television of the present invention is used to quickly illuminate a light-emitting body (LED) representing a power source on a TV work panel when the television is turned on, while avoiding the user repeatedly. Pressing an AC power switch of the TV causes the AC power switch and related parts to be easily damaged. 2 is a flow chart of a method for quickly turning on the television of the present invention. First, first, in step %10, press an AC power switch to turn on the LCD TV. In step S220, a microprocessor of the liquid crystal television is first initialized. Therefore, in step S220, not only the microprocessor but also the internal memory of the microprocessor is set. The external memory used by the microprocessor is also tested. 7 1330038 In step S230, the microprocessor executes a program to illuminate a light emitting diode (LED) on the television work panel. At this time, since the LED representing the power source has been illuminated, the user does not mistakenly think that the LCD TV is malfunctioning. Therefore, the problem that the AC power switch and related components are easily damaged due to the user repeatedly pressing the AC power switch can be avoided. In step S240, the television enters a standby-by mode to save power. Step S210 to step S230 is a cold booting step. In step S250, the microprocessor checks whether the power-on command from an infrared remote controller or the power-on command from the button on the television work panel, if any, proceeds to step S260, if not, Then it returns to step S250. In step S260, the microprocessor executes the program and performs initialization and setting on the peripheral components. The microprocessor performs initialization of a scaler (Scalar), a video decoder, a sound decoder, and a television tuner on the television through a sequence of busses. The sequence bus can be an I2C bus or a 15 RS232 bus. As the size of the TV becomes larger and the functions increase, the register of the peripheral components of the TV also increases relatively, which increases the initialization and setting time. Therefore, the present invention moves the initialization and setting of the peripheral components to the power-on command of receiving the infrared remote controller or the power-on command of the button on the work panel, so that the television can quickly receive the user's instruction after being turned on, and 20 is free to use. The person feels impatient. Steps S260 through S280 are so-called hot start steps. In step S270, is there a signal source detected? If yes, step 280 is performed, and if not, step S270 is returned. In step S270, the power of the display panel of the liquid crystal television is turned on to display an image of the signal source. 8 1330038 • Fig. 3 Schematic diagram of the boot time of the TV set, and the boot time diagram of the fast boot method of the invention. As shown in Figures 3 and 4, at time T. When the AC power switch is pressed to activate the television set, the present invention illuminates the __light emitting diode 5 (LED) on the television work panel at time T] (less than ice). The conventional television set lights up on the TV at time T2 (about 9 seconds), the light-emitting diode (LED) on the board. & The television of the present invention can illuminate the light-emitting diode and quickly receive the user's command after pressing the AC power source less than ice, and the conventional television set presses the AC power source After that, it takes about 9 seconds to illuminate the LED and receive the user's 10 commands. In summary, the present invention changes the booting process of a conventional television set, and upon illumination of a microprocessor of the television, rapidly illuminates a light-emitting diode (LED) representing the power source on the television work panel. After less than 丨 seconds, the π light-emitting diode can be clicked and the user's command can be quickly received, which can prevent 15 users from repeatedly pressing an AC power switch of the TV, thereby causing the AC power switch and related parts to be easily damaged.
