Problems solved by technology

However, using the reset chip faces the following disadvantages: 1. The operation voltage specification of the reset chip needs to be carefully selected
If the operating voltage of the reset chip is too small, it will not be able to supply the voltage required for the gate drive chip to be turned on, and if the reset chip whose operating voltage is close to the input voltage (Vin) of the LCD panel is selected, the input voltage will suffer from noise. When it is affected, it may also cause the reset chip to make a wrong judgment and cause a malfunction
2. A reset chip with the function of turning on all gate drive chips at the same time must be used
3. Using the reset chip will increase the cost

Embodiment Construction

[0031] First, please refer to figure 1 The timing controller block diagram of a preferred embodiment of the present invention, the timing controller 1 receives multiple external signals, such as: DE (Data Enable), Vin, etc., and controls multiple data drivers 2 and multiple scan drivers 3 The working clock is used to transmit a plurality of picture display data to a liquid crystal display panel (not shown in the figure) via the data driver 2 and the scan driver 3, so that the liquid crystal display panel can display pictures.

[0032] As shown in the figure, the timing controller 1 includes: a data receiving unit 11 , a data detecting unit 12 , a low-drive screen display data generating unit 13 , a data output unit 14 , a processing unit 15 and a data transmitting unit 16 .

[0033] The data detection unit 12 is electrically connected to the data receiving unit 11, the data output unit 14 and the low-drive screen display data generating unit 13 are both electrically connected ...

Abstract

The invention relates to a time schedule controller and a display signal processing control method thereof, which detects the input external signals to judge whether the time schedule controller is stopped so as to send low driving scene display data to a liquid-crystal display panel in advance when the time schedule controller is stopped, cause the power discharge rates of a liquid-crystal capacitor and a storage capacitor of the liquid-crystal display panel to be increased and shorten the power discharge rate of residual electric charge, thus lowering the occurrence possibility of tides.

Description

technical field [0001] The invention relates to a timing controller and a display signal processing control method thereof, especially to a timing controller suitable for a liquid crystal display panel and a display signal processing control method thereof. Background technique [0002] The display principle of the liquid crystal display panel (LCD) is to control the driving voltage of the panel to control the electric field between the liquid crystal capacitor and the storage capacitor in the panel, so that the liquid crystal interposed therein flips according to the electric field and controls the output of the display light source. Taking a normally white type LCD panel (NormallyWhite Type LCD) as an example, when the backlight is turned on and no driving voltage is given to keep the liquid crystal in a non-inverted state, it presents a white screen, and when a predetermined driving voltage is given, the liquid crystal When flipped, the screen will show light and dark cha...
