AMOLED Panel Data Line Sharing for Bezel Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current AMOLED display panels with a 'Pentile' pixel arrangement require two data lines per pixel, increasing the quantity of fan-out wires and the height of the fan-out area, which is not optimal for minimizing the lower bezel size.
Innovation Solution
The AMOLED display panel design alternately disposes first and second pixel units along horizontal and vertical directions, allowing sub-pixels to share data lines, reducing the overall number of data lines and fan-out wires, and incorporates a 7T1C pixel circuit with specific transistor and capacitor configurations to enhance efficiency and reduce bezel size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a 'Pentile' pixel arrangement is used with two data lines per pixel, then the pixel structure can be formed, but the quantity of fan-out wires increases and the height of the fan-out area increases
Solution Approach 1:
The patent merges the data line requirements by implementing a shared data line architecture where adjacent pixel units share common data lines. Specifically, first and second pixel units share a first data line, and first and third pixel units share a second data line, reducing the total number of data lines from two per pixel to one shared line serving multiple pixels.
Solution Approach 2:
The data lines are designed to serve multiple functions and multiple pixel units simultaneously. The first data line serves both the first and second pixel units, while the second data line serves both the first and third pixel units, making each data line universal rather than dedicated to a single pixel.

AI summary
The present disclosure provides an active-matrix organic light-emitting diode (AMOLED) display panel and a display device. The AMOLED display panel includes a plurality of first pixel units and a plurality of second pixel units. The first pixel unit includes a first sub-pixel and a second sub-pixel. The present disclosure is achieved by the first sub-pixel and the second sub-pixel in the first pixel unit to share one of the data lines, and by another first sub-pixel and a third sub-pixel in the second pixel unit to share one of the data lines, such that a quantity of data lines and a quantity of fan-out wires are reduced, so as to reduce a size of a lower bezel.
