Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display devices with organic electro luminescence (EL) pixels arranged in a two-dimensional matrix have a complex configuration due to the need to transmit image signals to every pair of pixel rows, complicating the display device setup.
Innovation Solution
A display device with a simplified configuration, where pixels are divided into first and second pixel groups, with image signals transmitted in common for each column via separate data lines, allowing for a more streamlined arrangement and efficient signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image signals are transmitted to every pair of pixel rows using separate data lines, then image quality and response speed are improved, but device complexity increases
Solution Approach 1:
The pixel array is divided into two separate pixel groups (first pixel group and second pixel group), each with its own dedicated data lines. This segmentation allows independent signal transmission to each group, improving image quality and response speed while managing complexity through organized separation rather than complete individual addressing of all pixels.
Solution Approach 2:
The patent introduces a new dimension of organization by dividing pixels into two distinct groups that are driven by separate data line sets. This dimensional change in the addressing architecture allows for higher quality display while maintaining manageable system complexity through structured grouping.
2Speed
If separate data lines are provided for first and second pixel groups, then signal transmission speed is improved, but number of data lines increases
Solution Approach 1:
By segmenting the pixel array into two groups with dedicated data lines, the patent achieves faster signal transmission to each group while limiting the total number of data lines needed. Each group receives signals through its own set of data lines, avoiding the need for individual addressing of every pixel.
Solution Approach 2:
The patent applies partial action by providing separate data lines for only two pixel groups rather than for every individual pixel or every single row. This partial separation achieves the speed benefit where needed while avoiding the excessive complexity of complete individual pixel addressing.
3Device complexity
If pixels in adjacent rows are driven as single pixels, then configuration is simplified, but high-gradation display capability is reduced
Solution Approach 1:
The patent segments the pixel array into two distinct pixel groups that can be independently controlled. This segmentation enables high-gradation display by allowing individual pixel addressing within each group while maintaining configuration simplicity through the organized two-group structure with dedicated data lines.
Solution Approach 2:
By introducing a two-dimensional grouping structure (first pixel group and second pixel group with separate data lines), the patent achieves both high-gradation display capability and configuration simplicity. The dimensional organization allows for independent control of each group while maintaining an overall simplified architecture.

AI summary
The pixel array unit (10) is configured by a plurality of pixels including light emitting elements and pixel circuits that cause the light emitting elements to emit light and arranged in a two-dimensional matrix. Data lines (70) are arranged for each of columns in the pixel array unit (10) and transmit image signals of the pixels. A first pixel group (121) is configured by pixels arranged in a plurality of adjacent rows. A second pixel group (122) is configured by pixels arranged in a plurality of adjacent rows and is arranged adjacent to the first pixel group (122). In the pixels of the first pixel group (121), the image signals are transmitted in common for each of the columns via the data lines (70) and, in the pixels (122) of the second pixel group, the image signals are transmitted in common for each of the columns via a data line different from the data line that transmits the image signals to the first pixel group (121).
