Embodiment 1

[0036] Please refer to figure 1 , figure 1 This is a flowchart of Embodiment 1 of the method for controlling a partitioned backlight provided by the present invention. The method includes:

[0037] S100. Detect the current value of each partition of the backlight.

[0038] Specifically, the brightness of the screen backlight is adjusted according to the brightness data of the image displayed on the screen, and the brightness adjustment of the backlight is controlled by current, that is, the current of the screen backlight reflects the brightness of the screen backlight, and the screen backlight The brighter it is, the more heat is generated. In this embodiment, the current value of each partition of the detected backlight can reflect the brightness of the screen backlight, thereby reflecting the heating degree of the screen backlight.

[0039] In this embodiment, the screen is displayed by using Local Dimming (regional dimming) technology, that is, the backlight of the scr...

Embodiment 2

[0079] Based on the above embodiments, the present invention also provides a terminal, the principle block diagram of which can be as follows image 3 shown. The terminal includes a processor, a memory, a network interface, a display screen, and a temperature sensor connected through a system bus. Among them, the processor of the terminal is used to provide computing and control capabilities. The memory of the terminal includes a non-volatile storage medium and an internal memory. The nonvolatile storage medium stores an operating system and a computer program. The internal memory provides an environment for the execution of the operating system and computer programs in the non-volatile storage medium. The network interface of the terminal is used to communicate with external terminals through a network connection. The computer program, when executed by the processor, implements a method for controlling a partitioned backlight. The display screen of the terminal may be a ...

Embodiment 3

[0103] The present invention also provides a storage medium, the storage medium stores one or more programs, and the one or more programs can be executed by one or more processors, so as to realize the partitioned backlight control described in the above embodiments steps of the method.

Abstract

The invention discloses a partition backlight control method, a terminal and a storage medium. The partition backlight control method includes: detecting the current value of each partition of the backlight; judging whether the sum of the currents of the partitions is Exceeding a preset threshold value; when the sum of the currents exceeds the preset threshold value, reducing the current of the partition to a preset safe threshold current within a subsequent second time period. The present invention determines the target current of the sub-area in the subsequent second time-length according to the current sum of the backlight sub-area in the first time-length, and then controls the luminous brightness of the screen backlight, and can adjust the backlight in time when the temperature rise of the backlight is too high. The actual brightness prevents the safety risk of the backlight due to overheating, and improves the safety of the screen backlight.

Description

technical field [0001] The present invention relates to the technical field of backlight, and in particular, to a method, terminal and storage medium for controlling a partitioned backlight. Background technique [0002] Local Dimming refers to a technology in which the backlight of the display screen can be adjusted in different regions. When using this technology to realize the screen display, the contrast of the display screen can be improved. However, when viewing high-contrast high-definition pictures for a long time, some areas of the backlight will maintain high brightness for a long time and continue to heat up, causing some areas of the backlight to overheat, posing a potential safety hazard. [0003] Therefore, the existing technology still needs to be improved and improved. SUMMARY OF THE INVENTION [0004] The technical problem to be solved by the present invention is to provide a partitioned backlight control method, terminal and storage medium in view of the...
