Problems solved by technology

However, when the driving current becomes too small, it is not easy to drive the display element, and flickering phenomenon will appear when the display device is activated to display at a lower gray scale value.

Abstract

A display method of a display device comprises the following steps: detecting a start signal of the display device; outputting a first control signal to the display device if the start signal is detected and a display gray scale record of the display device is a gray scale value of a second value; responding to the first control signal via the display device, and starting at the gray scale value of a first value; outputting a second control signal to the display device after the first control signal is outputted; responding to the second control signal via the display device, and displaying atthe gray scale value of the second value. The display device and the display method are provided; when the display device is started from a closed state and to display with a low gray scale value, the method outputs a control signal of another gray scale value greater than said low gray scale value, and outputs another control signal corresponding to the low gray scale value, thus driving the display device, and enabling the display device to eliminate the scintillation phenomenon in a replay display state process without increasing extra hardware cost.

Description

【Technical field】 [0001] The present invention relates to display technology, in particular to a display device and a display method thereof. 【Background technique】 [0002] Generally speaking, the display grayscale of the display device can be set according to the application environment, user needs, etc., so that the display device can display with different brightness. At present, when a display device displays with a high display gray scale, its maximum display brightness can reach more than 1000 nits, and when it displays with a low display gray scale, its minimum display brightness can reach 2.6 nits. [0003] With the development of the times, users have more and more stringent demands on the display brightness of the display device. For example, users of military police units and intelligence units need to be able to operate the display device when fighting at night, and do not expose their location due to the high display brightness of the display device. Therefore...
