AI Technical Summary

Technical Problem

Existing display devices struggle to achieve efficient image display in areas where electronic components are located, especially in the transmission area of ​​the component area, which limits the expansion of the display area.

Method used

By introducing an auxiliary pixel circuit and a bottom metal layer in the display device, the initialization voltage transmission of the auxiliary pixel circuit is realized, and a transmission area is set in the component area to allow the transmission of light and sound, while maintaining the image display function. The auxiliary pixel circuit includes an auxiliary driving thin film transistor and an initialization thin film transistor to support the initialization of the display element.

Benefits of technology

It enables efficient image display within areas containing electronic components, expands the functionality of the display area, improves the product reliability and light transmittance of display devices, and reduces damage to pixel circuits caused by electrostatic discharge.
