Display Module Support Column Placement for Optical Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in achieving a full-screen electronic device is the space occupied by driving mechanisms for components like cameras, which affects the screen-to-body ratio and optical performance due to weak support at light-transmissive holes, leading to recesses and reduced performance.
Innovation Solution
A display module with a light-transmissive hole and support columns positioned outside the hole, where at least part of the support column is located in a region other than the photosensitive area, enhancing support force without affecting light transmittance, and optionally using an annular light-shielding component to prevent stray light, ensuring better optical performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If no support column is disposed in the light-transmissive hole to maintain light transmittance, then light transmittance is preserved, but support force at the light-transmissive hole becomes weak causing recesses and affecting optical performance
Solution Approach 1:
The patent applies local quality by differentiating the support column arrangement in different regions: the light-transmissive hole region has no support columns to maintain light transmittance, while surrounding regions have support columns for structural support. This spatial differentiation resolves the contradiction between light transmittance and support force.
2Adaptability or versatility
If a driving mechanism is disposed in the housing to enable camera entry and exit, then camera functions are achieved, but large internal space is occupied reducing screen-to-body ratio
Solution Approach 1:
The patent extracts the camera module from the traditional driving mechanism structure and integrates it directly with the display module. The camera is positioned at the light-transmissive hole of the display module, eliminating the need for separate driving mechanisms and reducing internal space occupation.
3Area of stationary object
If support columns are distributed outside the light-transmissive hole region, then less space is occupied and screen-to-body ratio increases, but support force at the light-transmissive hole becomes insufficient
Solution Approach 1:
The patent implements local quality by creating a differentiated support structure where support columns are strategically positioned in non-light-transmissive regions to provide maximum support force without interfering with light transmittance. This allows the light-transmissive hole to maintain optical performance while the surrounding areas receive adequate structural support.

AI summary
A display module and an electronic device are provided. The display module includes: a light-transmissive cover plate, a first substrate (100), a second substrate (200), and a first support column (300). The second substrate (200) has a first region (B) and a second region (C). The second region (C) is a region, corresponding to a field-of-view range of an optical component, on the second substrate (200). The first region (B) is located in the second region (C), and the first region (B) is a region, corresponding to a photosensitive region of the optical component, on the second substrate (200). The first support column (300) is disposed between the first substrate (100) and the second substrate (200). At least a part of the first support column (300) is located in a third region, which is a region other than the first region (B) in the second region (C).
