Description of the invention: [Technical field to which the invention pertains] and particularly related to the invention The invention relates to a display method for a liquid crystal television. [Prior Art] 近年来 In recent years, the optoelectronic technology and the semi-correction of the brain have become more and more flat. Among them, the LCD TV is based on the advantages of μ electric weight and small volume, and has gradually replaced the (10) Yin Pai tube TV and became the mainstream of TV products in recent years. When a conventional LCD TV does not receive an RF-free signal or the peripheral audio-visual equipment has no signal input, it will display a snow-like face or blue screen to let the user know that there is no signal status. At this time, the backlight provided by the backlight module of the LCD TV still maintains the original brightness and consumes the power, thereby causing unnecessary energy waste of Q. In addition, when the signal input by the peripheral audio-visual device is fixed, for example, when the user presses the pause button, the backlight provided by the backlight module also maintains the original brightness and wastes energy. With the gradual rise of environmental awareness and the increasing demand for energy-saving products, some traditional LCD TVs will directly turn off the backlight module and LCD panel of the LCD TV to save energy when the signal input or input signal is fixed for a period of time. . However, this method will make it impossible for the user to understand that the LCD TV is turned off because no signal input or input signal is fixed, which causes the user to have inconvenience when using the liquid crystal television. 201044361 w ^ - I, Ιχ γ * [Invention] The present invention provides a display method of a liquid crystal television, which can achieve an energy saving effect without reducing the convenience of use of the liquid crystal television. A display method of a liquid crystal television of the present invention includes the following few steps. First, a backlight module of the LCD TV is turned on to provide a factory backlight with a second/brightness, and a liquid crystal panel of the liquid crystal television is turned on to continuously display an input signal provided by a signal source. Then, when the input signal provided by the signal source remains unchanged or the signal source stops providing the input signal for more than a predetermined period of time, the brightness of the backlight provided by the backlight module is lowered from the first brightness and the liquid crystal is continuously turned on. panel. Then, when the input signal provided by the signal source starts to change again or the signal source resumes providing the input signal, the brightness of the backlight provided by the backlight module is restored to the first brightness. In an embodiment of the display method of the liquid crystal television of the present invention, the step of reducing the brightness of the backlight source includes gradually reducing the brightness of the backlight. In an embodiment of the display method of the liquid crystal television of the present invention, the step of reducing the brightness of the backlight source includes turning off the backlight module. In an embodiment of the display method of the liquid crystal television of the present invention, the step of reducing the brightness of the backlight includes reducing the magnitude of the driving current of the backlight module. In an embodiment of the display method of the liquid crystal television of the present invention, The method further includes setting a preset period by a user. Based on the above, the display method of the liquid crystal television of the present invention can achieve the energy-saving purpose by utilizing the degree of freedom of the backlight, and can increase the liquid crystal television by allowing the user to open the liquid crystal panel to understand the current state of use: 201044361 7 v,...doc/n Convenience [Embodiment] = A diagram showing a display method of a liquid crystal television according to the present invention.

LCD panel use _=Day sneak peek includes 钤π啼π哚, ", the board is used to display the source, computer or other signal source provided by the source. ^. The source is for example DVD The player and the wired/wireless TV light module are used to provide the liquid crystal panel. === For example, using a cold cathode fluorescent tube and a two-parameter, 'Fig. 1' first turn on the backlight module of the LCD TV to provide -- The brightness of the back wire, the LCD panel of the same phase LCD TV to continue to display the input signal provided by the signal source, as in step sl〇. Specifically, the first brightness of the f-light source provided by the step S1G towel backlight module is based on the principle that the liquid crystal television can be normally displayed. Generally, the first brightness referred to herein allows the user to adjust to his or her preference. Then, in step S20, when the input signal provided by the signal source remains uninterrupted for more than a predetermined period of time, or when the signal source stops providing the input signal for more than the preset period, the backlight provided by the backlight module is provided. The brightness of the source begins to decrease from the first brightness and continues to open the liquid crystal panel. For example, when the LCD TV is turned on, the status of the input signal provided by the signal source is continuously detected. When the input signal provided by the signal source remains unchanged (for example, w/n 201044361 user presses the pause button of the DVD player) and remains unchanged for more than the preset period, the brightness of the backlight is changed from the first brightness. Start to lower. Alternatively, the source of the three §fl sources no longer provides an input signal (for example, the television signal is disconnected or the program is finished), and the time when the signal is not turned on exceeds the preset period, and the brightness of the backlight is also lowered from the first brightness. Among them, the brightness of the backlight can be gradually reduced or directly reduced to a preset brightness. Finally, you can choose to fully turn off the backlight or maintain the brightness of the backlight at a lower level than the first brightness, while continuously turning on the LCD panel' to allow the user to clearly see that the current LCD TV is in an abnormal display state. In addition, the aforementioned preset period may be set by the manufacturer of the LCD TV before the factory, but it may also be provided to the user according to the requirements, and the method for reducing the brightness of the backlight is, for example, reducing the backlight module. The size of the drive current.
