Solution Overview
Problem
Existing display devices face challenges in achieving high visibility and low power consumption, particularly in varying lighting conditions, and are limited to displaying images on a single flat surface.
Innovation Solution
A display device with separate regions for reflective and light-emitting elements, utilizing a polarizing plate and oxide semiconductors, allows for flexible display surfaces and reduces power consumption by selectively activating display regions based on ambient light conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a backlight is used in transmissive liquid crystal display devices, then visibility is improved, but power consumption increases
Solution Approach 1:
The display device is divided into multiple display regions, with some regions using reflective elements and others using light-emitting elements. This segmentation allows different parts of the display to operate in different modes, combining the low power consumption advantage of reflective displays with the high visibility advantage of light-emitting displays.
Solution Approach 2:
Different display regions are assigned different functional qualities: reflective display elements are used in regions where low power consumption is prioritized, while light-emitting elements are used in regions where high visibility is prioritized. This local differentiation allows optimization of both power consumption and visibility across the display.
2Use of energy by moving object
If reflective liquid crystal display devices are used, then power consumption is reduced, but visibility in low light conditions deteriorates
Solution Approach 1:
The invention merges reflective display elements and light-emitting display elements into a single display device. The reflective elements provide low power consumption operation, while the light-emitting elements compensate for visibility issues in low light conditions. Both types of elements work together to achieve both low power consumption and good visibility.
3Ease of manufacture
If display devices are limited to flat surfaces, then manufacturing is simplified, but display versatility deteriorates
Solution Approach 1:
The display device uses flexible display elements that can be formed on both flat and curved surfaces. The display regions are constructed using thin-film technologies that allow bending and shaping, enabling the display to adapt to various surface geometries while maintaining manufacturing feasibility through established flexible display fabrication techniques.

AI summary
A display device includes a first region and a second region adjacent to the first region. A display element included in the first region has a function of reflecting visible light and a function of emitting visible light. A display element included in the second region has a function of emitting visible light. In an electronic device including the display device, the first region is located on a first surface (e.g., top surface) on which a main image is displayed, and the second region is located on a second surface (e.g., side surface) on which an auxiliary image is displayed.
