MATRIX SUBSTRATE AND LIQUID CRYSTAL PANEL Russian patent published in 2017 - IPC G02F1/1368 

FIELD: physics.

SUBSTANCE: matrix substrate includes the first scan lines, data lines, pixels and a common electrode. Each pixel corresponds to one first scan line and one data line, and includes a first electrode, a second electrode, a first switch, a second switch, a third switch, a first capacitor and a voltage compensation circuit. In this case, the first scan line of the current pixel is connected to the first switch and the second switch. The corresponding data line of the current pixel is respectively connected to the first pixel electrode and the second pixel electrode via the first switch and the second switch. The third switch is connected to the corresponding first scanning line of the next pixel, the current pixel and the next pixel are located in the scanning direction, and the next pixel is located next to the current pixel. The second pixel electrode is connected to one terminal of the first capacitor through the third switch, the other terminal of the first capacitor is connected to the common electrode. The voltage compensation circuit is connected to the corresponding second electrode of the current pixel and connected to the corresponding first scan line of another further located pixel and the next pixel is located between the current pixel and the further located pixel in the scanning direction. The first scan lines are scanned in the scanning direction in turn, and the scanning signals are led to the corresponding first scan line of the next pixel to turn on the third switch of the current pixel. The voltage of the second electrode of the current pixel is changed by the first capacitor, whose capacity, when reversed, is greater than the capacitance of the first capacitor when reversed in negative polarity. When the scanning signals are input to the corresponding first scan line of the further located pixel, the current pixel voltage compensation circuit acts on the second electrode of the current pixel so that the ratio of the voltage difference between the second pixel electrode and the common electrode to the voltage difference between the first pixel electrode and the common electrode when reversed polarity is the same as the ratio when reversed polarity is reversed.

EFFECT: enhance the effect of small colour changes with a large viewing angle, reduce the effect of burning out pixels.
