Low-power-consumption display device for mobile terminal and control method of low-power-consumption display device

Abstract

The invention discloses a low-power-consumption display device for a mobile terminal and a control method of the low-power-consumption display device. The low-power-consumption display device comprises a transparent display layer and a reflecting type display layer. The transparent display layer is arranged above the reflecting type display layer and has a self-luminous function after being powered on. The display device conducts display through the self-luminous function of the transparent display layer or an environment light reflecting function of the reflecting type display layer. Through the technical scheme, display can be achieved by reflecting environment light when the environment light is sufficient, and the power consumption can be easily lowered; display can be achieved through the self-luminous function when the environment light is not sufficient. The display effect of a strong light environment and the display effect of a weak light environment are both achieved, the power consumption is low, and the runtime of a battery of the mobile terminal can be easily prolonged.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to a display device with low power consumption for a mobile terminal and a control method thereof. Background technique [0002] Display screens currently widely used in consumer mobile terminals include: TFT-LCD, Amoled, Pmoled, STN-LCD, Eink electronic paper, PLCD, Memory-LCD, and Mirasol. When the existing display screens use self-illumination or backlight to achieve display, the display effect is better in weak light environments, but the display effect is poor in strong light environments and consumes a lot of power; on the other hand, the existing display screens use external light reflection When displaying, the display effect is displayed in a strong light environment, but the display color performance is not good in a low light environment; in order to take into account the display effect in a strong light environment and a low light environment, a display screen wi...

Problems solved by technology

When the existing display screens use self-illumination or backlight to achieve display, the display effect is better in low light environments, but the display effect is poor in strong light environments and consumes a lot of power; on the other hand, the existing display screens use external light reflection When displaying, the display effect is displayed in a strong light environment, but the display color performance is not good in a low light environment; in order to take into account the display effect in a strong light environment and a low light environment, a display screen with a semi-transparent and semi-reflective process principle appears. However, the display effect of this kind of display screen is not ideal at present, and the power consumption is high.

[0003] Consumer electronics are very sensitive to battery life, especially wearable products, due to their small size, the space left for batteries is very limited, battery life has become a bottleneck in the industry, and the display screen is the most important component of power consumption in this type of electronic products. Therefore, the power consumption of the display screen of wearable smart terminals is a problem that needs to be improved urgently.
