Description

technical field [0001] The invention relates to a display device, in particular to a reflective display device and a front light source module thereof. Background technique [0002] With the 5th Generation Mobile Networks (5th Generation Mobile Networks), that is, the development and promotion of 5G communication technology, ultra-high-speed communication has opened the door to imaginative applications for massive wireless data transmission, and the corresponding information receiving and display devices will also be Enter the era of technical demands for ultra-high resolution and low power consumption. The expected convenience of information transmission will greatly increase the time of using the display device. In order to take into account both low power consumption and improved eye protection for long-term viewing, the technical development of new-generation reflective display panel-related components has become an important topic. [0003] Different from traditional ...

AI Technical Summary

Problems solved by technology

[0003] Different from traditional direct-light display panels (such as LCD, OLED, MicroLED, etc.), reflective display panels are similar to the light reflection characteristics of paper, and have the characteristics of high visibility under sunlight, power saving, and thinness. Self-illuminating reflective panels, in the absence of external light sources, the visibility of the panel will be greatly reduced, so how to provide reflective panels with a stable source of illumination without affecting the display screen will determine future reflective panel products Can the key elements of popularization be applied
