example 1
[0057] Example 1: If Figure 4 As shown, the specific steps of the display control method of the display device are as follows:
[0058] S401. The sound recognition unit collects audio;
[0059] If the voice recognition unit collects the audio, then execute step S402 and step S403; if the voice recognition unit does not collect the audio, then execute step S404 and step S405;
[0060] S402. The voice recognition unit sends a first control signal to the control backlight unit;
[0061] S403. Control the brightness of the display device to remain unchanged when the backlight unit receives the first control signal sent by the voice recognition unit;
[0062] S404. The voice recognition unit sends a second control signal to the control backlight unit;
[0063] S405. Control the backlight unit to adjust the brightness of the display device when receiving the second control signal sent by the voice recognition unit.
[0064] So far, through the above steps provided in Example 1,...
example 2
[0065] Example 2: If Figure 5 As shown, the specific steps of the display control method of the display device are as follows:
[0066] S501. The voice recognition unit collects audio; if the voice recognition unit collects audio, execute steps S502 and S503; if the voice recognition unit does not collect audio, execute step S504;
[0067] S502. The voice recognition unit sends a first control signal to the control backlight unit;
[0068] S503. Control the brightness of the display device to remain unchanged when the backlight unit receives the first control signal sent by the voice recognition unit;
[0069] S504. The voice recognition unit sends a third control signal to the screen detection unit to detect whether the screen dwell time of the display device meets the set threshold; if the screen dwell time is greater than or equal to the set threshold, then execute steps S505 and S506; if If the screen dwell time is less than the set threshold, then step S507 and step S5...

Abstract
The invention discloses a display device and a regulating system for regulating brightness of the display device. The regulating system comprises a sound recognition unit and a backlight control unit; the sound recognition unit is used for acquiring audio according to a set acquiring strategy, and sending a first control signal to the backlight control unit if the audio is acquired, and sending a second control signal to the backlight control unit if the audio is not acquired; the backlight control unit is used for controlling the unchanged brightness of the display device while receiving the first control signal sent by the sound recognition unit, and regulating the brightness of the display device while receiving the second control signal sent by the sound recognition unit. The regulating system provided by the embodiment of the invention can realize intelligent light-dimming through non-manual operation so as to automatically regulate the backlight brightness.
Description
technical field [0001] The invention relates to the field of display technology, in particular to an adjustment system and a display device for adjusting the brightness of a display device. Background technique [0002] At present, with the rapid development of technology display, large-size transparent splicing screens bring immersive visual experience to users, and the interactive combination of screens and exhibition objects brings shocking display effects, which are welcomed by the market. [0003] Such as figure 1 As shown, the splicing screen includes a cabinet 01, a backlight module 02 and a plurality of display modules 03 ( figure 1 3*3 display modules are shown in ); wherein, the cabinet 01 is located on the periphery of multiple display modules 03, and is used to fix multiple display modules 03, and the exhibition objects are placed on the bottom of the cabinet 01; the backlight module 02 can be located on the four side walls of the box body 01 to provide light f...
