Transflective Display Panel Resolving Mode Interference

Solution Overview

Problem

Existing transflective display apparatuses face interference between self-display and reflective display modes, leading to inefficient energy use and suboptimal display quality due to mutual interference, as they fail to complement each other effectively under varying ambient light conditions.

Innovation Solution

A display panel comprising reflective and self-display pixels, arranged in a matrix with independent control, where reflective pixels function as a display region under strong ambient light and self-display pixels as a black matrix, and vice versa under weak ambient light, to prevent mutual interference and enhance display effectiveness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If self-display pixels are used in transflective display apparatus, then image display can be achieved using transmitted light or self-emitted light, but energy is wasted and reflective display effect is affected when ambient light is strong

Engineering Contradiction:

Improvedisplay brightnessVSAvoidenergy waste

Core Design Contradiction:

Illumination intensityVSLoss of energy

Solution Approach 1:

The display panel is divided into two independent types of pixels: self-display pixels and reflective pixels. Each pixel type is dedicated to a specific display mode, allowing the system to select the appropriate pixel type based on ambient light conditions without mutual interference

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The display system dynamically switches between self-display pixels and reflective pixels based on ambient light detection. When ambient light is strong, reflective pixels are activated; when ambient light is weak, self-display pixels are activated, optimizing energy consumption and display quality in real-time

Inventive Principle:
