Embodiment 1

[0029] figure 1 The implementation process of the brightness control method provided by the first embodiment of the present invention is shown. For the convenience of description, only the parts related to the embodiment of the present invention are shown, and the details are as follows:

[0030] In step S101, brightness control information, a cycle count value, and the number of data refresh display cycles are generated according to the setting of the user terminal.

[0031] Wherein, the brightness control information includes single or multiple fixed brightness control data, or single or multiple brightness change control data, or single or multiple fixed brightness control data and single or multiple brightness change control data. The fixed brightness control data is used to control the light emitting device to display a fixed brightness, and the brightness change control data is used to control the light emitting device to display a brightness change.

[0032] Wherein, t...

Abstract

The invention provides a method and a device for controlling brightness, which belongs to the field of brightness control. In the invention, needed brightness control data are generated according to the brightness variation parameter of a lighting device set at user sides; and the brightness control data are sent according to the data sending sequence set at the user sides to conduct brightness control of the lighting device at time division, so s to realize rapid brightness control and good brightness variation display effect of the lighting device. The method and the device provided by the invention solves the problems of large output data quantity, much redundant data and wastes of resources of a main control system in the brightness control method in the prior art.

Description

technical field [0001] The invention belongs to the field of brightness control, in particular to a brightness control method and device. Background technique [0002] At present, LED and other light-emitting devices have been widely used in digital display, home lighting, industrial searchlight and other fields, and in the process of using LED and other light-emitting devices, it is often necessary to adjust the display effect of LED and other light-emitting devices, for example, to make more One of the LED lights gradually lights up or fades out, and the other LED lights keep the original display state. This requires driving the LED light according to the preset lighting time and working current to achieve a specific display effect. [0003] In the existing brightness control technology, the method of digital dimming is usually adopted, and the brightness control data is sent once in each data display refresh cycle to control the display of the light emitting device. How...
