FIELD: physics.
SUBSTANCE: matrix substrate includes first scan lines (SL1), second scan lines (SL2), third scan lines (SL3), data lines (DL), pixels and common electrode (CE). SL2 are electrically connected in the peripheral region of the matrix substrate. 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 and pixel E3. Each pixel further includes a first control circuit (CC1) and a second control circuit (CC2). The LEDs are respectively connected to the pixel E1, the pixel E2 and the pixel E3 through S1, S2 and S3 to provide a data signal. S1, S2 and S3 are switched on, when SL1 brings the first scanning signal. CC1 is connected to the CE. CC1 adjusts the voltage difference between the pixel E1 and the CE so that it is zero when the SL2 feeds the second scan signal, so that the pixel E1 is in the display state of the image corresponding to the black screen. CC2 affects the pixel's E2 and the pixel's E3 when the SL3 supplies a third scan signal that changes the voltage difference between the pixel's E2 and the pixel's E3. In 2D mode, the E1 pixel, pixel E2, and pixel E3 are in the image display state corresponding to the 2D image, under the influence of SL1 and DL. CC1 translates pixel E1 status display an image, the corresponding 2D image when the SL2 brings fourth signal scan, and then brings the third scan signal SL3 for CC2 management to influence the second pixel and the pixel E3. The voltage difference between the pixel's E2 and the pixel's E3 varies under the influence of CC2, so that there are voltage differences that are not equal to zero between pixel E1, pixel E2 and pixel E3. In 3D mode, the SL2 feeds the second scan signal to control the CC1 to affect the pixel E1. E2 of the pixel and E3 of the pixel are in the state of displaying the image corresponding to 3D, under the influence of SL1 and DL corresponding to this pixel. E1 of the pixel is in the display state of the image corresponding to the black screen under the influence of CC1, and then the SL3 feeds the third scanning signal to control the CC2 to affect the pixel E2 and the pixel E3. The voltage difference between the pixel's E2 and the pixel's E3 changes under the influence of CC2, so that there is a voltage difference that is not zero between the pixel's E2 and the pixel's E3.
EFFECT: reduces the difference in colour at a wide viewing angle, improves the window format in 2D mode and reduces crosstalk signals for two eyes in 3D mode, and reduces the number of data drivers.
