MATRIX SUBSTRIPTION AND LCD PANEL Russian patent published in 2017 - IPC G02F1/1362 

FIELD: physics.

SUBSTANCE: matrix substrate includes first scan lines (FSL), second scan lines (SSL), third scan lines (TSL), data lines (DL), pixels and common electrode (CE). In this case, each pixel corresponds to the FSL, SSL, TSL and DL. Each pixel includes a first pixel electrode (E1), a second pixel electrode (E2), a third pixel electrode (E3) and a first switch (S1), a second switch (S2) and a third switch (S3), which respectively affect the pixel E1, pixel E2 and pixel E3. Each pixel further includes a first control circuit (CC1) and a second control circuit (CC2). The DL corresponding to the pixel is connected via S1, S2 and S3 to E1 of the pixel, E2 of the pixel and E3 of the pixel, respectively, for feeding the data signal. S1, S2 and S3 are conductive when the FSL corresponding to a given pixel supplies the first scanning signal. CC1 is connected to the CE, with CC1 acting on the E1 of the pixel when the SSL corresponding to the given pixel supplies the second scan signal, so that the zero voltage difference between the pixel E1 and the OE translates the pixel E1 into a state corresponding to the black image display. The CC2 is connected to the CE, and the CC2 acts on the pixel E2 when the TSL corresponding to the given pixel supplies a third scanning signal to change the pixel voltage E2. In 2D mode, E1 of the pixel, E2 of the pixel and the E3 of the pixel are in a state corresponding to display 2D images under the influence of a FSL and DL, corresponding to a given pixel. CC1 is in a state corresponding to display 2D images when the fourth scan signal is lead by the SSL. Then, the TSL adds a third scan signal to ensure the action of the CC2 on the E2 of the second pixel. In this case, the pixel voltage E2 changes under the action of the CC2, so that the E2 of the pixel has a corresponding non-zero voltage difference from the E1 of the pixel and the E3 of the pixel. In the 3D display mode, the SSL provides a second scan signal to ensure the action of the CC1 on the E1 of the pixel. E2 of the pixel and E3 of this pixel are in the state corresponding to the 3D image display under the action of the FSL and DL. E1 of the pixel is in the state corresponding to the display of the black image under the action of CC1. Then, the TSL adds a third scan signal to ensure the action of the CC2 on the E2 of the second pixel. In this case, the pixel voltage E2 changes under the action of the CC2, so that the E2 of the pixel has a corresponding non-zero voltage difference from the E3 of the pixel.

EFFECT: reducing the colour difference at a wide viewing angle, increases the window format in 2D mode, reduces crosstalk between signals in 3D mode and reduces the number of data line drivers.
