Liquid Crystal Display Pitch Layout for Viewpoint-Shifted Brightness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices experience display quality degradation due to viewpoint positional displacement, leading to insufficient brightness at displaced viewpoints.
Innovation Solution
A display device with a liquid crystal display panel and light source configuration where the pitch between light emission points is 1:4n or 1:6n times the pixel pitch, and pixels are controlled to form a light-transmitting region twice as wide as the pixel width, allowing for improved image output to multiple viewpoints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional image separation band is provided in correspondence with the position of a viewpoint expected in advance, then individual image output to multiple viewpoints is achieved, but display quality degradation occurs at displaced viewpoints
Solution Approach 1:
The patent applies dynamics by making the light-transmitting region width variable rather than fixed. The width is set to twice the pixel width, which dynamically adapts to accommodate viewpoint displacement while maintaining proper light separation. This dynamic dimension allows the system to handle multiple viewpoints effectively without quality degradation.
Solution Approach 2:
The patent changes the parameter of light-transmitting region width to twice the pixel width. This parameter change ensures that the light separation function remains effective even when the viewpoint position shifts, thereby maintaining display quality across different viewing positions while still enabling individual image output to multiple viewpoints.
2Manufacturing precision
If the pitch between light emission points is set to 1:4n or 1:6n times the pixel pitch, then optimal light separation is achieved, but device complexity increases
Solution Approach 1:
The patent specifies precise parameter values for the pitch ratio between light emission points and pixels (1:4n or 1:6n). This parameter change optimizes the light separation function by ensuring proper spatial relationship between light sources and pixel elements, achieving high manufacturing precision in light separation while managing device complexity through standardized ratio configurations.

AI summary
A display device includes a liquid crystal display panel with pixels and a light source with light emission points. A ratio of a pitch between the pixels arranged in a first direction to a pitch between the light emission points arranged in the first direction is 1:4n or 1:6n. Each pixel includes sub pixels arranged in the first direction. A first pixel and one or more of the sub pixels included in a second pixel are controlled to form a light-transmitting region, the first pixel is positioned on a ray line of light between a user's viewpoint and one of the light emission points and controlled to transmit light, and the one or more of the sub pixels are arranged adjacent to the first pixel in the first direction and controlled to transmit light. A width of the transmission region in the first direction is twice that of each pixel.
