Liquid Crystal Display With Light Transmission Hole
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies face challenges in achieving full-screen displays on smartphones while maintaining camera functionality, as solutions often require hardware modifications or sacrifices in cost, production processes, or user experience.
Innovation Solution
A liquid crystal display (LCD) design that incorporates a first light-transmission hole and a colorless region, allowing light to pass through for image acquisition and enabling full-screen display by using a backlight to illuminate the colorless region, while the lens is positioned to receive light through the hole, ensuring both functions are realized.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hole or notch is formed in the display panel to accommodate the front camera, then camera functionality is maintained, but the full-screen display effect is compromised
Solution Approach 1:
The patent merges the camera opening region with the display region by placing a light source in the opening and using a light guide plate to distribute light across the entire display area, making the camera region part of the display rather than a separate functional element
Solution Approach 2:
The opening in the display panel serves multiple functions: it accommodates the front camera while also housing a light source that contributes to the overall display illumination, making the same structural feature serve both camera and display purposes
2Adaptability or versatility
If an ejectable component is provided to maintain camera functionality, then camera access is ensured, but device complexity and user experience are degraded
Solution Approach 1:
The patent extracts the light source from the traditional backlight assembly and places it directly in the camera opening, eliminating the need for complex mechanical ejection mechanisms while maintaining camera functionality
Solution Approach 2:
The backlight system is segmented into multiple light sources positioned at different locations (including the camera opening), with each segment contributing to different portions of the display area through the light guide plate
3Adaptability or versatility
If a light guide plate with holes is used to accommodate camera openings, then camera functionality is maintained, but display uniformity and light distribution are affected
Solution Approach 1:
The patent applies local quality by positioning specific light sources at strategic locations (including the camera opening) and using a light guide plate with varying optical properties in different regions to achieve uniform overall light distribution despite localized light sources
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for a true full-screen display and image acquisition function without compromising on camera functionality, improving user experience and display quality by maintaining high light-transmittance and coherence.
Implementation Method 1
a backlight layer 1, an inner polarizing layer 2, an array substrate 3, a liquid crystal layer 4, a filter layer 5, an outer polarizing layer 6 and a protective layer which are sequentially disposed. When the liquid crystal display is in operation, the backlight layer 1 emits light
Implementation Method 2
the backlight layer 1 emits light to provide a light source to the liquid crystal display, and the backlight layer 1 usually emits white light
Implementation Method 3
a first light-transmission hole 11 is formed on the backlight layer 1... both the first light-transmission hole and the colorless region in the liquid crystal display have light-transmittance

AI summary
The present disclosure relates to a display panel, a terminal and a terminal control method, and belongs to terminal technologies. The liquid crystal display includes a backlight layer, a colorless region and a backlight. The backlight layer is provided in which a first light-transmission hole is formed. The colorless region is provided between a liquid crystal layer and an outer polarizing layer and corresponding to the first light-transmission hole. The backlight is disposed at the first light-transmission hole and its light is projected on liquid crystal display and corresponds to the colorless region.
