Solution Overview
Problem
The impedance values of polarizers and backplates in OLED display modules are high, leading to issues with static electricity accumulation and affecting overall photoelectric performance.
Innovation Solution
Incorporating an antistatic agent into the polarizing and backplate layers of the display module, particularly in adhesive layers adjacent to the display panel, to reduce impedance and enhance conductivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If polarizers and backplates are disposed on both sides of the display panel, then display effects are improved and protecting effects are provided, but impedance values of these layers become large causing static electricity accumulation
Solution Approach 1:
The patent changes the electrical parameter (impedance) of the polarizer and backplate layers by incorporating antistatic agents. This modifies the material composition to reduce impedance values while maintaining the protective and display functions of these layers.
Solution Approach 2:
The patent creates composite material structures by combining polarizing materials and backplate materials with antistatic agents. This results in multi-functional layers that simultaneously provide protection, display enhancement, and static electricity dissipation.
2Object-affected harmful factors
If antistatic agent is added to polarizing layer or backplate layer, then impedance value is reduced and antistatic effect is improved, but manufacturing process becomes more complex
Solution Approach 1:
The patent merges the antistatic function with the existing polarizing or backplate layers by incorporating antistatic agents during the layer formation process. This combines multiple functions (protection, display enhancement, and static dissipation) into single integrated layers, simplifying the overall manufacturing process.
Solution Approach 2:
The patent makes the polarizing and backplate layers multi-functional by adding antistatic properties to them. These layers simultaneously serve as protective barriers, display enhancement elements, and static electricity dissipation paths, reducing the need for separate components.

AI summary
A display module and a mobile terminal are disclosed. The display module includes a display panel, a polarizing layer disposed on a first side of the display panel, and a backplate layer disposed on a second side of the display panel, and the polarizing layer or/and the backplate layer includes an antistatic agent. By adding the antistatic agent into the polarizing layer or/and the backplate layer, the present disclosure reduces an impedance value of the polarizing layer or/and the backplate layer, improves an antistatic effect, thereby improving overall photoelectric performances of the display module.
