Display Device Signal Routing for Under-Panel Camera Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When integrating a camera module under a display panel, the connection of pixels between the general display region and the region with the camera module can result in incorrect voltage for the pixels, affecting display quality.
Innovation Solution
The display device is designed with a substrate having first and second signal lines that extend in different directions within a third region between the first and second regions, allowing for correct transmission of gate signals and reducing the impact of diffraction on the camera module.

1Area of stationary object
If the camera module is arranged under the display panel, then the frame size is reduced or the display region is increased, but the pixels may receive wrong voltage or the wire design may affect display quality
Solution Approach 1:
The display panel is divided into a first display region and a second display region with different wiring configurations. The third region serves as a transition zone where signal lines are routed separately, allowing independent voltage control for pixels in each region, thus ensuring correct voltage delivery while accommodating the camera module underneath.
Solution Approach 2:
A third region is introduced as an intermediary zone between the first and second display regions. This intermediate region contains dedicated signal lines that mediate the connection between pixels in different regions, ensuring proper voltage transmission to pixels in the second region without interference from the camera module placement.
2Device complexity
If signal lines are routed directly between regions, then the wiring is simplified, but diffraction effects may occur and display quality may be affected
Solution Approach 1:
Signal lines in the third region are configured to extend in multiple directions rather than following a single straight path. This multi-directional routing in the intermediate zone allows signal lines to bypass areas that would cause diffraction effects while still connecting pixels in different regions, thereby reducing diffraction without significantly increasing wiring complexity.

AI summary
An electronic device having a first region, a second region, and a third region set between the first region and the second region is provided. The electronic device includes a substrate, a first signal line disposed on the substrate, and a second signal line disposed on the substrate. The first signal line has two portions disposed in the third region and the two portions of the first signal line extends along two directions respectively. The second signal line has two portions disposed in the third region, the two portions of the second signal line extends along two directions respectively, and at least one of the first signal line and the second signal line is configured to transmit a gate signal. In the third region, the first signal line crosses the second signal line.
