Abstract

The invention discloses a display device, and the display device comprises a liquid crystal display panel and a backlight, wherein the liquid crystal display panel comprises a liquid crystal cell, a first polarizer arranged on one liquid crystal cell side adjacent to the backlight and a second polarizer arranged on the other liquid crystal cell side far away from the backlight, and at least one of the first polarizer and the second polarizer is of the moveable polarizer. In the display device, the polarizer in a display unit is configured into a movable structure, under adverse conditions, in particular for dark environment, the brightness of the display device can be improved by adjusting the polarizer position to achieve the illumination function, so that an user can send out a distress signal to save himself through lights emitted by the display device.

Description

technical field [0001] The present invention relates to the display field, in particular to a display device. Background technique [0002] In recent years, wearable devices have gradually become popular among users because they are easy to wear and convenient for users to use at any time. At this stage, there are different forms of electronic devices such as glasses, hat brims, and watches. Smart devices, through which users can view and record real-time data such as time, exercise, and sleep in daily life, and can also synchronize these data with other electronic devices, greatly improving the quality of people's lives. [0003] However, the functions of current smart watches are mainly aimed at people's entertainment activities, and when people face difficulties, especially in dark environments, the smart watches they carry are far from being able to realize people's self-help. Contents of the invention [0004] (1) Technical problems to be solved [0005] The technic...
