Embodiment Construction

[0038] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] refer to figure 1 , figure 1 It is a schematic flowchart of an embodiment of a method for adjusting the brightness of a display terminal backlight according to the present invention. In this embodiment, the method for adjusting the brightness of the display terminal backlight includes:

[0040] Step S10, using the spectrum sensor to detect and identify the type of ambient light source where the display terminal is currently located;

[0041] In this embodiment, different ambient light sources correspond to different spectra, such as Figure 2-5 See the schematic diagram of the spectral curve of the indoor ambient light source shown. Therefore, a spectrum sensor may be provided on the display terminal to detect and identify the type of ambient light source where the display terminal is currently located, suc...

Abstract

The invention discloses a method for adjusting the backlight brightness of a display terminal. The method includes the steps of detecting and identifying the ambient light source type of the place where the display terminal is currently located through a spectrum sensor, correspondingly selecting light perception output compensation coefficient according to the identified environment light source type to conducting light perception compensation for the optical sensor, obtaining the corresponding light perception characteristic curve after light perception compensation has been done to the spectrum sensor, and adjusting the backlight brightness of the display terminal according to the light perception characteristic curve and corresponding preset backlight brightness adjusting experimental value. The invention further discloses an apparatus for adjusting the backlight brightness of a display terminal and a television set. The backlight brightness of a display terminal can be adjusted according to different environmental light sources, so that the display terminal allows a user to watch more comfortable under different environmental light sources, excessively high or low backlight brightness of the display terminal due to different ambient light sources can be prevented, and the user experience for watching is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for adjusting the brightness of a backlight of a display terminal and a television. Background technique [0002] With the continuous tightening of energy-saving and environmental protection laws and regulations in various countries, TVs and other display products are being promoted to continuously introduce various energy-saving technologies, such as automatically adjusting the backlight of TVs according to changes in ambient light, that is, to meet the needs of users to watch TV. At the same time, it also meets the needs of reducing energy consumption, so as to achieve the purpose of energy saving and emission reduction. However, the existing technical solutions for adjusting the brightness of the display terminal backlight are only designed for a specific typical ambient light source, such as a fluorescent light source, and if the fluorescent light s...
