Embodiment 1

[0046] figure 1 It is a flow chart of a multi-zone backlight control method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of multi-zone backlight control. The method can be implemented by a terminal, specifically through software and / or hardware in the terminal. implement. see figure 1 , the multi-zone backlight control method includes the following steps:

[0047] S110. Acquire configuration data of the display screen, and acquire frame image data.

[0048] The display terminal based on local backlight (Local Dimming) adjustment can complete multi-zone backlight control. The backlight partition matrix can contain multiple LED backlight lamp beads, and multi-zone backlight control can be realized by adjusting the brightness of the LED backlight lamp beads in each backlight partition.

[0049] In this embodiment, the display terminal capable of multi-zone backlight control is usually a display terminal that adjusts the bac...

Embodiment 2

[0070] In this embodiment, on the basis of the foregoing embodiments, the multi-zone backlight control method is optimized. The specific optimization method is: when the system is started, start the constant current control module; when the constant current control module is started, check whether the communication with the constant current control module is normal; when the communication is normal, initialize the constant current control module. This embodiment has the same inventive concept as the above-mentioned embodiment, and explanations of terms that are the same as or corresponding to those of the above-mentioned embodiment will not be repeated in this embodiment.

[0071] figure 2 It is a flowchart of a multi-zone backlight control method provided by Embodiment 2 of the present invention. see figure 2 , the method includes the following steps:

[0072] S210, when the system is started, start the constant current control module;

[0073] S220. When the constant ...

Embodiment 3

[0085] image 3 It is a schematic structural diagram of a multi-zone backlight control device provided in Embodiment 3 of the present invention, and this embodiment is applicable to multi-zone backlight control.

[0086] see image 3 , the multi-zone backlight control device in this embodiment includes:

[0087] A data acquisition module 310, configured to acquire configuration data of the display screen, and acquire frame image data;

[0088] The target backlight data determination module 320 is used to determine the target backlight data of the frame image data in each partition of the display screen according to the configuration data;

[0089] The backlight brightness adjustment module 330 is used to control the constant current control module to adjust the backlight brightness of each partition of the display screen according to the configuration data and the target backlight data when the flag bit of the backlight control is in the control state.

[0090] Optionally, ...

Abstract

The embodiment of the invention discloses a multi-zone backlight control method and device, a terminal and a storage medium, and the method comprises the steps: obtaining the configuration data of a display screen, and obtaining the frame image data; determining target backlight data of the frame image data in each partition of the display screen according to the configuration data; and when the flag bit of backlight control is in a control state, controlling a constant current control module to adjust the backlight brightness of each partition of the display screen according to the configuration data and the target backlight data. According to the multi-zone backlight control method and device, the terminal and the storage medium provided by the embodiment of the invention, multi-zone backlight control is completed through the system chip and the constant-current control chip, so that the cost can be effectively saved.

Description

technical field [0001] Embodiments of the present invention relate to display screen technology, and in particular to a multi-zone backlight control method, device, terminal and storage medium. Background technique [0002] With the continuous development of display technology, display terminals (such as TVs or computers) can automatically adjust the backlight brightness corresponding to the bright and dark parts of the display screen, so that the bright parts of the screen are brighter and the dark parts reflect more details, that is, to improve image dynamic contrast while reducing backlight power consumption. [0003] In the prior art, the commonly used multi-zone backlight control method is that the system chip (System on Chip, SOC) collects image signals and sends them to the power control chip; the power control chip processes the image signals to obtain the backlight brightness of different matrix areas, and Control the constant current control chip to adjust the cur...
