A display device with a pixel region featuring uniform-sized pixels and low-resolution areas where adjacent pixels display the same gray level, reducing the effective resolution and data requirements, and incorporating a driving unit that connects multiple lines to a single terminal to reduce pixel count and improve charging efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the pitch of pixels in peripheral parts is increased compared with the center part, then the total number of pixels is reduced and data amount is decreased, but the pixel electrode size and line pitch become non-uniform, complicating manufacturing control
Solution Approach 1:
The patent applies local quality by creating a low-resolution area in the peripheral parts of the display screen where m pixels display an identical gray level, while maintaining normal pixel resolution in the center part. This allows the total number of pixels to be reduced and data amount to be decreased without affecting the center display quality, while avoiding the manufacturing complexity of non-uniform pixel electrode sizes and line pitches.
2Quantity of substance
If the density of pixels in peripheral parts is set smaller than the center part, then the total number of pixels is reduced and data transfer rate is decreased, but the line pitch becomes non-uniform, reducing manufacturing efficiency
Solution Approach 1:
The patent implements local quality by designating a low-resolution area in the peripheral parts where m pixels (adjacent in at least one direction) display an identical gray level. This configuration reduces the effective pixel count and data transfer requirements while maintaining uniform line pitch and pixel electrode size across the entire display screen, thereby preserving manufacturing efficiency and productivity.
3Loss of information
If the resolution in peripheral parts is decreased compared with the center part, then the amount of data is reduced and computation load is decreased, but the pixel electrode size and line pitch become non-uniform, increasing process complexity
Solution Approach 1:
The patent applies local quality by creating a low-resolution area in the peripheral parts where m pixels display an identical gray level, reducing the amount of data and computation load. This approach maintains uniform pixel electrode size and line pitch across the entire display screen, avoiding the need to control complex non-uniform process conditions while still achieving the goal of reducing data and computation requirements.

AI summary
A display device includes: a pixel region that includes a plurality of pixels arranged in matrix; a plurality of lines connected to the pixels, the lines including a plurality of gate lines that extend in a first direction and a plurality of source lines that extend in a second direction; and a driving unit that includes a gate driver that drives the gate lines, and a source driver that drives the source lines. In this display device, the pixels have a uniform size, and the pixel region has a low-resolution area in which m pixels (m is a natural number equal to or more than 2) adjacent in at least one of the first direction and the second direction display an identical gray level at all times.
