Abstract

The invention provides a display device and a control method thereof. The display device includes a display panel including a plurality of display partitions, and a control unit which is electrically coupled with a display module and is configured to determine a target display partition in the plurality of display partitions, conduct smoothing treatment on gray-scale values of the plurality of pixel points of the target display partition to obtain updated gray-scale values of the plurality of pixel points of the target display partition, and drive the target display partition of the display panel based on the updated gray scale values of the plurality of pixel points of the target display partition.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a display device and a control method thereof. Background technique [0002] Today, with the continuous development of information and display technology, people's pursuit of display technology effects is getting higher and higher. The traditional liquid crystal display (LCD) has gradually been unable to meet people's pursuit of high contrast and high color gamut. In the related art, a plurality of light-emitting units in the backlight module are independently controlled as a group, that is, regional control is realized, and local partial area dimming can be realized, which has higher brightness and contrast than traditional backlights. However, there is a halo problem in this control method, that is, the border between the bright area and the dark area cannot be clearly demarcated, thus forming a halo phenomenon. Contents of the invention [0003] The disclosur...
