Liquid Crystal Panel Camera Integration for Narrower Display Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with both a display portion and a camera on the same surface face challenges in reducing the outer frame width while maintaining space for the camera, and there is a desire for capturing sharp pictures.
Innovation Solution
A display device configuration that includes a liquid crystal panel with first and second regions overlaid on the camera, controlled to transmit different amounts of light through these regions, using polarizers and a controller to adjust light transmission modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the camera is provided outside the display portion, then the camera can be installed with sufficient space, but the outer frame width of the display portion increases
Solution Approach 1:
The camera and display portion are merged into a single integrated structure where the camera is positioned behind the display portion at a specific distance, allowing both functions to coexist within the same spatial envelope without increasing the outer frame width
Solution Approach 2:
The camera is positioned in the depth dimension (distance from display surface) rather than the lateral dimensions, allowing camera installation space to be created along the Z-axis without increasing the X-Y plane dimensions of the display
2Illumination intensity
If a color filter is provided in the display portion, then color display is achieved, but the color filter absorbs part of the light incident on the camera
Solution Approach 1:
The display portion is segmented into a display region with color filters for color display and a camera region without color filters for optimal light transmission, allowing both color display and adequate camera illumination to coexist
Solution Approach 2:
Different regions of the display portion have different optical properties: the display region contains color filters for color reproduction while the camera region excludes color filters to maximize light transmission to the camera sensor
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
This configuration allows for reduced frame width by integrating the camera into the display portion, minimizing color filter influence, and adjusts light quantity based on ambient conditions for sharp imaging.
Implementation Method 1
a liquid crystal panel located between the first polarizer and the second polarizer
Implementation Method 2

AI summary
According to one embodiment, an electronic apparatus includes a camera, a first polarizer, a second polarizer, a liquid crystal panel, and a controller controlling the liquid crystal panel. The liquid crystal panel includes a first region and a second region. The controller controls a first opening mode of transmitting light through the first region and the second region, and a second opening mode of making a quantity of light transmitted through the first region smaller than a quantity of light transmitted through the second region.
