Liquid Crystal Panel with Segmented Transparent and Color Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transparent displays often suffer from visual interference where dynamic messages overlap with products behind them, especially when messages and products have similar colors, affecting the exhibition effect.
Innovation Solution
A liquid crystal panel is partitioned into a transparent section for viewing products and a color section for displaying dynamic messages, with larger first subpixels in the transparent section and smaller second subpixels in the color section, each equipped with red, green, and blue photoresists, and a backlight module behind the color section for illumination.

1Productivity
If a transparent display is used to show messages in shop windows, then product information can be displayed dynamically, but the messages interfere with the view of products behind when viewed from different heights or angles
Solution Approach 1:
The liquid crystal panel is divided into two distinct sections: a transparent section for displaying product information and a color section for showing dynamic messages. This segmentation allows the display to simultaneously maintain transparency for product visibility while providing dynamic message display, thereby resolving the visual interference problem.
Solution Approach 2:
Different regions of the display panel are assigned different optical properties. The transparent section maintains high light transmittance for product visibility, while the color section provides full-color dynamic message display. This local differentiation of functional properties enables both transparency and dynamic display without mutual interference.
2Measurement precision
If the transparent section has larger subpixels for better product visibility, then viewing clarity improves, but the color display capability is reduced
Solution Approach 1:
The display panel is segmented into transparent and color sections, each optimized for its specific function. The transparent section uses larger subpixels for clear product visibility, while the color section uses smaller subpixels with full color capability for dynamic messages.
Solution Approach 2:
Different subpixel configurations are applied to different regions: larger subpixels in the transparent section for optimal viewing clarity, and smaller color-capable subpixels in the color section for versatile message display.

AI summary
A liquid crystal panel and a liquid crystal display are disclosed. The panel includes an array substrate, a filter substrate, and a liquid crystal layer. The filter substrate includes a filter sheet. The liquid crystal panel is partitioned into a transparent section and a color section, and the filter sheet includes a transparent photoresist corresponding to the transparent section, and a color photoresist corresponding to the color section. An exhibition device for showcasing products is also disclosed. The exhibition device includes a showcase, a lamp inside the showcase, and at least an above-described liquid crystal display and panel framed in one of the showcase's side wall. The lamp provides illumination to the transparent section and the showcased products may be viewed through the transparent section. The transparent section may also show static messages describing the showcased products. The color section presents dynamic messages demonstrating the showcased products.
