Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In liquid crystal display devices using the field sequential method, the high frequency of image signal input required to achieve high frame rates poses a challenge due to the need for high-speed response from transistors, which is difficult to improve without compromising the transistor's characteristics.
Innovation Solution
The liquid crystal display device is divided into multiple regions, allowing simultaneous selection of multiple scan lines and signal lines, enabling increased image signal input frequency without altering the response speed of transistors, thereby tripling the image signal input frequency.

1Productivity
If the image signal input frequency is increased to achieve high frame rates in field sequential method, then the display performance is improved, but the transistor response speed requirement becomes too high to be practically achievable
Solution Approach 1:
The pixel array is divided into multiple regions (first region, second region, third region) that are driven by different scan line groups. This segmentation allows the display to process multiple regions simultaneously with different image signals, effectively increasing the overall image signal input frequency without requiring individual transistors to respond faster than currently achievable.
2Productivity
If multiple scan lines are selected simultaneously to increase image signal input frequency, then the productivity is improved, but the device complexity increases
Solution Approach 1:
Scan lines are divided into multiple groups (first scan lines, second scan lines, third scan lines) that can be independently controlled. Each group can be selected and driven separately, allowing simultaneous processing of multiple regions while maintaining manageable control complexity through systematic grouping.
Solution Approach 2:
The invention provides a specific selection sequence for scan lines that is predetermined and systematic. By establishing this preliminary selection order, the control complexity is managed through a predefined pattern rather than requiring complex real-time decision-making logic.

AI summary
To increase the frequency of input of image signals, a pixel portion of a liquid crystal display device is divided into a plurality of regions, and input of image signals is controlled in each of the plurality of regions. As a result, a plurality of scan lines can be selected at the same time in the liquid crystal display device. That is, in the liquid crystal display device, image signals can be simultaneously supplied to pixels placed in a plurality of rows, among pixels arranged in matrix. Thus, the frequency of input of an image signal to each pixel can be increased without change in response speed of a transistor or the like included in the liquid crystal display device.
