Embodiment 2

[0118] The method for local dimming of a display device in this embodiment includes:

[0119] S500. Form the file directory name, and store the local dimming configuration parameters in the file where the file directory name is located;

[0120] In this embodiment, the screen attribute and the local dimming configuration parameter are stored separately, so as to facilitate the screen attribute to find the local dimming configuration parameter of the TV. A file directory name that is easy to find should be set in the second storage partition, and local dimming configuration parameters are stored in the file where the file directory name is located. For example, the file directory name can be the directory name including the machine core information of the display screen 104, the model information of the display screen 104, and the serial number of the screen parameters in the first embodiment, and can also be the machine core information of the display screen 104, The model in...

Abstract

The invention discloses a display device local dimming method, a display device and a storage medium. The display device comprises a first storage subarea and a second storage subarea which are located in different storage areas; and the method comprises the following steps: reading screen attributes of the display device from the first storage subarea; searching a local dimming configuration parameter corresponding to the screen attribute from the second storage partition according to a preset rule; controlling partition backlight brightness of the display device according to the local dimming configuration parameters; and when the display device carries out system software upgrading, upgrading the first storage partition or the second storage partition independently. The invention aims to solve the problem that system software of a television mainboard cannot be universally used due to different parameters such as local dimming subarea, subarea brightness precision, driving current and the like used on existing televisions with different models and different sizes.

Description

technical field [0001] The present invention relates to the field of display devices, in particular to a local dimming method for a display device, a display device and a storage medium. Background technique [0002] At present, LCD TVs are used more and more widely. From the perspective of technological development trends, how to reduce the power consumption of the backlight source has attracted the most attention. Because the backlight is the largest energy consumer, reducing the power consumption of the backlight greatly reduces the power consumption of the whole machine. The technologies include improving the driving circuit of the backlight source, improving the luminous efficiency of LEDs, and developing new types of LEDs. At present, Local Dimming (that is, local dimming) is the easiest to implement and the most effective technology among these technologies. In particular, the direct-lit LED backlight with local dimming technology can greatly reduce power consumption...
