Backlight Module Light Guide for Bright In-Plane Camera Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current backlight modules with in-plane holes in liquid crystal displays lack a light source to provide brightness, limiting their ability to achieve full-screen display.
Innovation Solution
Incorporating a light source device with a light guide at the wall of the in-plane hole to provide light to the area under predetermined conditions, such as when the camera is off, ensuring the hole is illuminated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an in-plane hole structure is used for camera placement, then the camera can be integrated into the display, but the hole area cannot provide display brightness
Solution Approach 1:
A light guide component is introduced as an intermediary element within the in-plane hole to transfer light from the main backlight area to the hole region. The light guide receives light from surrounding areas and redirects it to illuminate the hole, enabling the hole area to display images while maintaining camera integration functionality
2Ease of operation
If the hole area is used for camera light transmission, then ambient light can pass through, but no additional light source can be added
Solution Approach 1:
The in-plane hole structure is designed to serve multiple functions: it transmits ambient light to the camera when needed, and can also contain a light guide component to provide display brightness when the camera is not in use. This multi-functional design allows the same structure to adapt to different operational modes without adding excessive complexity

AI summary
The present invention provides a backlight module and a display device, wherein the backlight module includes an in-plane hole, and further includes a first light source and a second light source each independently driven and controlled; the light guide is disposed at a wall of the in-plane hole corresponding to the first light source, and is configured to provide light emitted by the first light source to an area of the in-plane hole under a predetermined condition. Compared with the prior art where the in-plane hole is only used as a channel for receiving and transmitting ambient light from the camera below the opening without light source to provide brightness, the embodiments of the present invention solve the problem in the prior art that in-plane holes in a backlight module of a liquid crystal display device have no light source to provide brightness, thereby realizing the in-plane hole of the backlight module with brightness under a predetermined condition, and providing more scene applications of the area of the in-plane hole.
