Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in achieving a full screen display on smartphones while maintaining the functionality of a front camera is that existing solutions either compromise on display quality or user experience, as integrating a camera beneath the liquid crystal display requires a hole that obstructs the display or involves costly and complex hardware modifications.
Innovation Solution
A liquid crystal display design featuring a backlight layer with a first light transmitting hole, a backlight member, and a lower pixel density in the corresponding region, allowing for improved light transmittance and simultaneous full screen display and camera image acquisition by optimizing the optical path and using a backlight member to provide light for the camera lens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hole is opened in the liquid crystal display to integrate a camera beneath the screen, then the image acquisition function is enabled, but the display quality and full screen effect are compromised
Solution Approach 1:
The liquid crystal display is divided into two functional regions: a first region with a lower pixel density that serves as the light transmitting hole for the camera, and a second region with a higher pixel density for normal display. This segmentation allows the camera function to be integrated without significantly impacting the overall display quality, as the first region occupies only a small portion of the total display area.
Solution Approach 2:
Different regions of the liquid crystal display are assigned different pixel densities according to their functional requirements. The first region corresponding to the camera position has a lower pixel density to facilitate light transmission, while the second region maintains a higher pixel density for optimal display performance. This local differentiation resolves the contradiction between camera functionality and display quality.
2Illumination intensity
If the pixel density in the camera region is reduced to improve light transmittance, then the image acquisition function is enhanced, but the display resolution in that region is compromised
Solution Approach 1:
Instead of uniformly reducing pixel density across the entire display, the invention applies partial action by reducing pixel density only in the specific first region where the camera is located. The rest of the display maintains its original high pixel density, thus achieving sufficient light transmittance for the camera while preserving display resolution in the majority of the display area.
3Adaptability or versatility
If a traditional camera integration method is used, then the camera function is achieved, but hardware complexity and manufacturing cost increase
Solution Approach 1:
The camera integration is achieved by merging the camera light path with the liquid crystal display structure. The first region of the liquid crystal display serves dual purposes: it acts as both a display area (with reduced pixel density) and a light transmitting hole for the camera. This merging eliminates the need for separate camera holes or complex hardware modifications, thereby reducing overall device complexity.

AI summary
The present disclosure provides a liquid crystal display, a display method, and a terminal, and belongs to the field of terminal technology. The liquid crystal display includes a backlight layer (1) and a backlight member (7). The backlight layer (1) is formed with a first light transmitting hole (11). The backlight member (7) is disposed at the first light transmitting hole (11), and the backlight member (7) emits light and the light is projected on a region of the liquid crystal display corresponding to the first light transmitting hole (11). A display pixel of the region of the liquid crystal display corresponding to the first light transmitting hole (11) is lower than that of a region of the liquid crystal display outside the first light transmitting hole (11). In the region corresponding to the first light transmitting hole (11), a transparent region exists between adjacent pixels.
