Engineering Contradiction Analysis
1Reliability
If the number of pixels in the overlapping region is decreased to prevent deterioration in electronic module performance, then the electronic module performance is improved, but the display quality deteriorates
Solution Approach 1:
The patent applies different processing algorithms to different regions of the display panel. Specifically, it distinguishes between a first region (with normal pixel density) and a second region (overlapping the electronic module with reduced pixel density). For the second region, the patent uses a dedicated compensation algorithm that references pixel values from the first region to generate appropriate display data, thereby maintaining display quality despite the reduced pixel count in the overlapping area.
2Adaptability or versatility
If the pixel density is reduced in the overlapping region, then the electronic module can function properly, but the image representation quality deteriorates
Solution Approach 1:
The patent introduces an intermediary processing mechanism where the drive controller acts as a mediator between the image signal and the display panel. For pixels in the second region (overlapping area), the controller generates display data by referencing not only local pixel values but also pixel values from the first region. This intermediary processing step compensates for the reduced pixel density and maintains image representation quality while allowing the electronic module to function properly in the overlapping region.

AI summary
A display device includes a display panel and a drive controller. The drive controller classifies an input image signal into a first image signal and a second image signal. The drive controller generates a data histogram by classifying the second image signal based on a plurality of gray levels and selects a first algorithm or a second algorithm based on a number of second image signals included in a part of the plurality of gray levels of the data histogram. The second algorithm calculates a second result value based on a first result value obtained based on the second image signal and a preset kernel matrix, and the drive controller outputs a first data signal corresponding to the second pixel unit in the second display region based on the second result value when the second algorithm is selected.
