Backlight adjusting method, device, system and computer program product

Abstract

The invention discloses a backlight adjusting method, device and system and a computer program product. The backlight adjusting method, device and system are applied to a backlight brightness adjuster of an ink screen system, and the ink screen system comprises an ink screen, light sensors, a local backlight brightness adjuster and a backlight brightness adjuster, wherein the light sensors are used for respectively sensing light rays irradiated on different areas of the ink screen; the light sensors are arranged below the ink screen; the local backlight brightness regulator is electrically connected with the backlight brightness regulator and the signal output end of each light sensor. The backlight adjusting method comprises the following steps: determining ambient light indexes corresponding to different areas; and if it is determined that illumination of the ink screen is not uniform according to the ambient light indexes corresponding to the different areas, performing backlight adjustment on at least one area in the different areas based on at least one ambient light index. According to the invention, the accuracy of ink screen backlight adjustment is improved, and the eye protection effect of the ink screen is further improved.

Description

technical field [0001] The present invention relates to the technical field of ink screens, in particular to a backlight adjustment method, device, system and computer program product. Background technique [0002] With the rapid development of science and technology, the scope of use of electronic equipment is becoming wider and wider. However, the luminescent screen of the electronic device will cause damage to the user's eyes, therefore, the display screen of the electronic device can use an ink screen to protect the user's eyes. [0003] At present, the ink screen backlight system can indeed achieve the brightness adjustment effect. However, the light sensor in the ink screen backlight system only receives the vertically projected ambient light. In actual use scenarios, the ambient light source is not all direct, and a considerable part of the light source is blocked when people are reading. Based on this, the screen brightness on the ink screen will show a partial shad...

[0003] At present, the ink screen backlight system can indeed achieve the brightness adjustment effect, however, the light sensor in the ink screen backlight system only receives the vertically projected ambient light

In actual use scenarios, the ambient light source is not all direct, and a considerable part of the light source is blocked when people are reading. Based on this, the screen brightness on the ink screen will show a partial shadow block, while the traditional ink screen only configures One light sensor, then the ambient light index calculated by the light sensor can only represent a part of the light perception on the ink screen, but cannot represent the overall light perception of the ink screen, that is, the calculated ambient light index is not completely consistent with the various positions of the ink screen. Same light perception

For example, when the light sensor can receive the light emitted by the light source, the ambient light in the shaded part of the ink screen is smaller than the ambient light index calculated by the light sensor. Adjusting the backlight will lead to inaccurate adjustment of the backlight of the ink screen, thereby reducing the eye protection effect of the ink screen
