Embodiment 1

[0023] An embodiment of the present invention provides a brightness adjustment method, such as figure 1 shown, including:

[0024] 11. Obtain real-time ambient light brightness signal parameters.

[0025] 12. Analyzing and processing the brightness signal parameters.

[0026] 13. Control the brightness of the display screen according to the analysis and processing results.

[0027] Wherein, in the brightness adjustment method, obtaining the external light brightness signal parameter is obtaining the external light intensity.

[0028] Wherein, when the real-time external brightness is greater than the brightness of the display screen, the brightness of the display screen is increased; when the real-time external brightness is smaller than the brightness of the display screen, the brightness of the display screen is decreased.

[0029] A brightness adjustment method provided by an embodiment of the present invention obtains real-time external light brightness signal parameter...

Embodiment 2

[0031] An embodiment of the present invention provides a brightness adjustment device, such as figure 2 shown, including:

[0032] The acquiring unit 21 is configured to acquire parameters of the ambient light brightness signal.

[0033] The processing unit 22 is configured to analyze and process the brightness signal parameters.

[0034] The control unit 23 is configured to control the brightness of the display screen according to the analysis and processing results.

[0035] A brightness adjustment device provided by an embodiment of the present invention obtains real-time external light brightness signal parameters; analyzes and processes the light brightness signal parameters; Compared with that, the present invention can effectively and comprehensively track the change of ambient light brightness, and eliminate the visual discomfort caused by the inconsistency between display parameters and ambient light through joint adjustment of brightness and contrast.
