Hybrid LCD Window Area for External Image Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display devices (LCDs) cannot display external images and are limited to showing video data only, lacking the capability to combine or mix video images with external images.
Innovation Solution
A hybrid type liquid crystal display device is designed with a window area within the display area, utilizing a first and second polarization film, a light guide panel, a reflection sheet, and a cover bottom with aperture areas to allow external images to be shown through the LCD panel, while maintaining the ability to display video data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional LCD panel is used to display video data, then video data can be represented on the display area, but external images cannot be shown through the LCD panel
Solution Approach 1:
The display area is segmented into a main display area for video data and a window area for external images. The polarization film is also segmented with a first polarization area covering the main display area and a second polarization area covering the window area, allowing different optical properties in different regions.
Solution Approach 2:
Different regions of the LCD panel are assigned different optical properties. The first polarization area has polarization axes oriented to display video data, while the second polarization area has polarization axes oriented to transmit external images. This local differentiation enables both video data display and external image transmission simultaneously.
2Adaptability or versatility
If polarization films are added to enable external image transmission, then display versatility is improved, but device complexity increases
Solution Approach 1:
The first and second polarization films are merged into a single integrated polarization film structure that covers both the main display area and the window area. This unified structure simplifies the device compared to having separate polarization films, while still enabling both video data display and external image transmission functions.
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
Enables the simultaneous representation of video data on the main display area and external images through the window area, creating complex images by combining video data with external images, enhancing the display capabilities of LCDs.
Implementation Method 1
a first polarization film disposed at front surface of the liquid crystal display panel with a first polarization axis
Implementation Method 2
a second polarization film disposed behind the liquid crystal display panel for polarizing the back light to a second polarization axis perpendicular to the first polarization axis
