Problems solved by technology

[0003] When switching between the shared state and the anti-peeping state, there will be a brightness change that can be discerned by the human eye. Therefore, the human eye can recognize the switching process between the shared state and the anti-peeping state, resulting in easy fatigue of the human eye

Abstract

The invention provides a display device, a backlight source and an automobile. The display device comprises a visual angle control box. In the sharing mode stage, the first electrode and the second electrode are provided with the same voltage; in the privacy mode stage, a first voltage is provided for the first electrode, an alternating voltage signal is provided for the second electrode, the high voltage of the alternating voltage signal is larger than the first voltage, and the low voltage of the alternating voltage signal is smaller than the first voltage; in the transition stage, a first voltage is provided for the first electrode, and a voltage signal with a gradually changing duty ratio is provided for the second electrode; wherein the transition stage is located between the sharing mode stage and the privacy mode stage, and the duty ratio is the ratio of the time occupied by the pulse to the total time in a period of continuous working time. The invention provides a display device, a backlight source and an automobile so as to gradually change the brightness under each visual angle and avoid abrupt change of the display brightness of the display device during switching between a sharing mode stage and a privacy mode stage, thereby improving eye fatigue.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device, a backlight source and an automobile. Background technique [0002] At present, people have different requirements for display product viewing angles in different occasions. For example, when multiple people can see the content of the display screen from different angles, it is required that the display product has a wide viewing angle, that is, a shared state; voyeurism. [0003] When switching between the shared state and the anti-peeping state, there will be a brightness change that can be discerned by the human eye. Therefore, the human eye can recognize the switching process between the shared state and the anti-peeping state, which will cause human eyes to be easily fatigued. Contents of the invention [0004] The present invention provides a display device, a backlight source and a car, which can gradually change the brightness at various viewing ang...
