Solution Overview
Problem
Conventional display devices face challenges in improving user convenience, particularly in achieving high definition image quality while maintaining low power consumption and adaptability to varying ambient light conditions.
Innovation Solution
The implementation of a display device with two types of display panels, one using light emitting elements for high definition image display and another using light control elements for reflective image display, which are controlled to optimize image quality and power usage based on the orientation and ambient light, allowing for multiple display modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If light emitting elements are used for display, then high definition image quality is achieved, but power consumption increases
Solution Approach 1:
The display device is divided into two separate display panels: a first display panel with light emitting elements for high definition images, and a second display panel with light control elements for standard definition images. This segmentation allows the system to use only the high power-consuming first panel when high definition quality is needed, while using the low power-consuming second panel for standard definition content, thus resolving the contradiction between image quality and power consumption.
Solution Approach 2:
The system dynamically switches between the first display panel (light emitting elements) and the second display panel (light control elements) based on the required image quality and power consumption conditions. The control unit determines which panel to activate, enabling the display device to adapt its power consumption and image quality characteristics to match the current usage scenario.
2Adaptability or versatility
If a single display panel is used, then device complexity is reduced, but adaptability to different display modes decreases
Solution Approach 1:
Each display panel is designed to be multi-functional: the first display panel can display both high definition and standard definition images, while the second display panel can display standard definition images. This universality allows the system to support multiple display modes (high definition only, standard definition only, or combined) without requiring entirely separate hardware configurations for each mode.
Solution Approach 2:
By segmenting the display system into two independent panels with different capabilities, the device achieves versatility in display modes. The first panel handles high definition requirements when needed, while the second panel provides standard definition display, allowing the system to adapt to various usage scenarios without increasing overall complexity significantly.
3Ease of operation
If transparent display mode is used, then user convenience is improved, but image quality may deteriorate
Solution Approach 1:
The system segments the display functionality by using the first display panel (with light emitting elements) for transparent display modes where high definition quality is not critical, and the second display panel (with light control elements) for standard definition transparent displays. This allows the system to provide transparent display functionality that improves user convenience while managing image quality expectations appropriately for each panel type.
