Embodiment 1
[0045] figure 1 is a schematic diagram of the structure of the array substrate in the first embodiment of the present application, see figure 1 As shown, the thin film transistor liquid crystal display (ie: TFT-LCD) includes: a display panel, and the display panel includes: an array substrate 100, an opposite substrate arranged in a cell with the array substrate 100, and a substrate sandwiched between the array substrate 100 and the opposite substrate LCD between. Liquid crystal is a capacitive material, and the liquid crystal capacitor 112 is the equivalent capacitor of liquid crystal. The size of the equivalent liquid crystal capacitor 112 is about 0.1pF. This capacitor cannot maintain the voltage until the next time the screen data is updated, so it is necessary to add another one. The storage capacitor 113 is used to keep the charged voltage until the next screen update.
[0046] The array substrate 100 includes a plurality of sub-pixels 110, the sub-pixels 110 include a...
Embodiment 2
[0059] Figure 5 is the input and output waveform diagram of the shaping unit in the second embodiment of the present application, see Figure 5 As shown, the difference between the second embodiment and the first embodiment is that the third clock signal CLK3 is a square wave signal.
[0060] It should be noted that, the third clock signal CLK3 may be a square wave signal, but is not limited thereto, and the third clock signal CLK3 may also be a sine wave signal, etc., depending on the situation.
[0061] The first clock signal CLK1 is deformed into a second clock signal CLK2 when it passes through the driving trace 300. The second clock signal CLK2 is not a square wave and has a certain delay in waveform relative to the first clock signal CLK1. The shaping unit 500 transforms the second clock signal CLK2. Shaping into a square wave signal, that is to say, through shaping, the influence of the resistance and capacitance on the driving trace 300 on the first clock signal CLK1...
Embodiment 3
[0080] The difference between the third embodiment and the second embodiment is that the upper threshold voltage VTH and the lower threshold voltage VTL of the Schmitt trigger in the third embodiment can be adjusted.
[0081] Figure 7 is the schematic circuit diagram of the Schmitt trigger in the third embodiment of the present application, Figure 8 is the input and output waveform diagram of the shaping unit in the third embodiment of the present application, see Figure 7 and Figure 8 As shown, the Schmitt trigger further includes a third resistor R3, a fourth resistor R4 and a selector, the third resistor R3 and the fourth resistor R4 are connected through a second node, and both the first node and the second node are selected through The selector is connected to the non-inverting input terminal of the operational amplifier 510, the selector selects the first node or the second node to be connected to the non-inverting input terminal of the operational amplifier 510, a...
