AI Technical Summary

Technical Problem

In conventional display devices, each pixel contains four sub-pixels, resulting in a large pixel area that is difficult to shrink further, affecting the transparency of the display device and the user's visibility.

Method used

In a display device, a method of arrangement is used in which three sub-pixels are set in one pixel, and sub-pixels of other colors are set in adjacent pixels to replace colors that cannot be displayed. For example, a pixel includes sub-pixels of three colors: red, green, and blue, and white sub-pixels are set in adjacent pixels to replace colors that cannot be displayed.

Benefits of technology

By reducing the number of subpixels per pixel, the area of ​​the transmissive region is increased, thereby improving the transparency of the display device while maintaining or improving the user's visibility.
