AI Technical Summary

Technical Problem

When curved display panels are bent, the color filter and pixel area become misaligned, causing crosstalk problems. Existing solutions, such as widening the black matrix, reduce the aperture ratio and increase power consumption.

Method used

By adjusting the spacing, width, and arrangement of the pixel electrodes and signal lines, the alignment between the color filter and the pixel electrodes is ensured. An overlapping and non-overlapping signal line design is adopted, combined with the setting of light-shielding strips in the black matrix, to reduce crosstalk and maintain a high aperture ratio.

Benefits of technology

It effectively reduces the relative positions of the color filter and multiple pixel electrodes at the edge of the curved display panel, thereby reducing crosstalk while maintaining a high aperture ratio and low power consumption.
