Problems solved by technology

However, due to the non-linear relationship between the magnitude of the current of the LED and the control voltage transmitted by the driving circuit of the LED, it is difficult to adjust the voltage through the control voltage signal.
If the miniaturized light source corresponding to each sub-pixel is increased, the complexity of the overall circuit will increase with the number of micro-LEDs
Therefore, when a display device uses miniaturized light-emitting diodes as light sources for display pixels, it is difficult to increase the resolution of the display device due to the above-mentioned problems.

Abstract

The present invention relates to a display device and its driving method. The display device includes a backlight module and a plurality of shutter groups on the backlight module, and each shutter group includes a plurality of sub-pixels. The backlight module includes a plurality of light-emitting arrays, and the light-emitting array includes a plurality of light-emitting areas arranged along the first direction. The position of each light-emitting array corresponds to the position of one of the shutter groups, and the sub-pixels of the shutter group are arranged along the second direction, and the first direction is not parallel to the second direction. When the light emitting regions in the light emitting array irradiate light beams, the illuminating light beams provided by each light emitting region can illuminate multiple sub-pixels.

Description

technical field [0001] The present invention relates to a display device and a driving method thereof, in particular to a display device with a direct backlight and a driving method thereof. Background technique [0002] Among the existing display technologies, technologies related to light emitting diodes (Light Emitting Diode, LED) have become one of the main characters. The technologies that occupy a major position in the light-emitting diode market include liquid crystal display (Liquid Crystal Display, LCD) technology with light-emitting diodes as backlight and organic light-emitting diode (Organic Light Emitting Diode, OLED) display technology. Improve these display technologies in terms of image quality and brightness. [0003] For example, when the backlight module uses light-emitting diodes as surface light sources, liquid crystal display technology will affect the appearance of black due to light leakage and other phenomena, and even affect the overall contrast of...
