AI Technical Summary

Technical Problem

When existing display devices reduce the proportion of harmful blue light, they can easily cause yellowing when displaying white pictures, affecting the true color display of the image source.

Method used

By introducing purple sub-pixels and sky-blue sub-pixels into the color film layer of the display panel, and controlling the brightness of these sub-pixels using the corresponding pixel driving structure, the avoidance of harmful blue light bands is achieved, and the purpose of mixing light is achieved.

Benefits of technology

It effectively alleviates the display of harmful blue light, avoids the appearance of harmful blue light bands, and maintains the accuracy of the display color, without affecting the true color display of the image.

Abstract

The invention discloses a display panel, a display device and electronic equipment, and the display panel comprises an array substrate and a color film substrate which are laminated; the color film substrate comprises a color film layer; the color film layer is divided into a plurality of pixel units which are periodically and repeatedly arranged, and each pixel unit comprises a red sub-pixel, a green sub-pixel, a purple sub-pixel and a sky blue sub-pixel; a first pixel driving structure corresponding to the sky-blue sub-pixel and a second pixel driving structure corresponding to the purple sub-pixel are arranged in the array substrate, and the first pixel driving structure is used for controlling the brightness of the sky-blue sub-pixel penetrating through the first target wave band light. The first pixel driving structure is used for controlling the brightness of the purple sub-pixel penetrating through the second target wave band light; harmful blue light display can be effectively relieved, and the accuracy of the display color is not affected.
