AI Technical Summary

Technical Problem

The prior art is difficult to achieve good touch display of large-size folding screen notebooks, mainly due to the large size and lack of mature technical solutions.

Method used

A display device is designed, including a display panel, a data driving unit, a touch driving unit and a bendable circuit board. The display panel has first and second display areas and is bent at the first bend area. When the display device is in a bent state, the bendable circuit board can transmit data signals and touch signals, thereby realizing independent touch display of the first and second display areas.

Benefits of technology

Through this design, a large-size folding display device can achieve good touch display, solving the problem that traditional technology cannot be applied to large-size folding screen notebooks.
