Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current OLED touch control display devices face challenges in manufacturing due to the use of flexible polymer antiglare layers, leading to increased thickness and reduced productivity, as well as potential damage to the organic material layer during the assembly of separate OLED and touch control panels.
Innovation Solution
The integration of a touch control panel between a transparent substrate and a glass cover plate, with a thin film package layer protecting the OLED thin film element and locating the antiglare layer on the cover plate to facilitate easier manufacturing, involves a glass substrate, a glass cover plate, reflective anode and transparent cathode metal layers, and inorganic passivation layers to construct a sealed OLED touch control display device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the OLED display device and touch control panel are separately manufactured and then assembled, then the touch control function can be provided, but the device thickness increases and manufacturing complexity increases
Solution Approach 1:
The patent merges the OLED display device and touch control panel into a single integrated structure. The touch control panel is positioned between the substrate and package cover plate of the OLED display device, eliminating the need for separate assembly and reducing overall device thickness while maintaining both display and touch control functions.
2Adaptability or versatility
If the touch control panel is assembled separately with the OLED display device, then the touch control function can be provided, but the manufacturing process becomes more complex and productivity decreases
Solution Approach 1:
The touch control panel is integrated into the OLED display device structure during the manufacturing process itself, rather than being assembled separately afterward. This allows both components to be produced in a single manufacturing cycle, improving productivity and reducing manufacturing complexity.
3Adaptability or versatility
If the touch control panel is assembled separately with the OLED display device, then the touch control function can be provided, but the risk of damaging the organic material layer increases
Solution Approach 1:
The touch control panel is positioned and secured between the substrate and package cover plate before the OLED display device is fully assembled. This preliminary positioning prevents subsequent handling and assembly operations from damaging the delicate organic material layer of the OLED display device.
4Illumination intensity
If the antiglare layer is made of flexible polymer material, then the display quality can be improved, but the manufacturing difficulty increases and productivity decreases
Solution Approach 1:
The patent replaces the flexible polymer antiglare layer with a rigid glass cover plate that has antiglare properties. This substitution simplifies the manufacturing process and increases productivity while maintaining the necessary display quality, as the glass cover plate is more stable and easier to manufacture than flexible polymer materials.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach reduces the thickness of the OLED touch control display device, prevents damage to the organic material layer, and simplifies the manufacturing process, thereby enhancing productivity by integrating the touch control panel directly between the substrate and cover plate and loading the antiglare layer on the cover plate.
Implementation Method 1
As the OLED display device works, the Hole and the Electron are injected to the emitting layer, these electrons and the holes are combined to generate excited electron-hole pairs, and the excited electron-hole pairs are converted from the excited state to the ground state for achieving illumination.
Implementation Method 2
a thin film package layer located on the OLED thin film element and completely covering the OLED thin film element
