Problems solved by technology

[0002] With the development of technology, all kinds of display screens are widely used in communication industry, household appliances industry, automobile industry and other fields, and the screen size is also becoming larger and larger. However, no specific definition is given for the screen brightness of the display screen. The brightness of the screen is too bright or too dark will cause damage to human eyes
The existing screen brightness display system has at least the following problems: 1. The screen brightness cannot be customized; 2. When the screen brightness is set to "automatic", it cannot automatically adapt to the brightness needs of different users; 3. The screen brightness is set to "automatic". ", it is highly dependent on the acquisition precision and accuracy of the illuminance acquisition module
The invention patent with the application number "200710028181.9" and the invention title "Method for Dynamically Adjusting Screen Brightness" discloses a method for dynamically adjusting the screen, which can learn the ambient luminosity and automatically match the brightness, but the luminosity and brightness are very smooth curves , the light intensity changes by 1lux, the brightness may be adjusted accordingly, which may cause the screen to flicker continuously due to light intensity changes
Moreover, this solution does not allow users to automatically define the screen brightness, but only presets some screen brightness, but everyone has different needs for screen brightness, and each person's eyes have different comfort levels for brightness.
Unified settings cannot meet modern people's requirements for personalization of electronic screens

Embodiment 1

[0055] The adaptive screen brightness adjustment method of the present invention, such as figure 1 shown, including:

[0056]S101: The user defines different screen brightness values ​​under different light intensities, and correspondingly saves the different light intensity values ​​and the different customized screen brightness values;

[0057] Choose the three most common light intensity environments, namely daytime, cloudy and night. According to daily experience, the stronger the light intensity, the brighter the screen brightness needs to be set, otherwise it will be impossible to see due to reflections. Clear the screen. Therefore, for the aforementioned environments such as daytime, cloudy day, and nighttime, the user sets a satisfactory screen brightness value respectively. In the specific implementation, the light intensity value at any time in the three environments of daytime, cloudy and night can be collected respectively through the light intensity acquisition ...

Embodiment 2

[0070] Such as figure 2 As shown, the difference between the technical solution of Embodiment 2 of the present invention and Embodiment 1 is that after the screen brightness value is calculated according to the formula, the screen brightness is not directly adjusted according to the value, but the following steps are further carried out: Judgment steps:

[0071] S205: Determine whether the value calculated according to the formula is greater than the maximum value of the screen brightness or smaller than the minimum value of the screen brightness, if so, proceed to step S206, otherwise proceed to step S207;

[0072] Comparing the screen brightness value calculated according to the formula B=B1(L / L1), B=B2(L / L2) or B=B3(L / L3) with the maximum or minimum value of the screen brightness, It is judged whether the calculated screen brightness value is greater than the maximum value or smaller than the minimum value. The maximum or minimum brightness of the screen here is the defa...

Abstract

The invention provides an adaptive screen brightness adjusting method and a system. The method comprises steps that screen brightness values are respectively customized by a user under different luminous intensities, and different luminous intensity values and the different customized screen brightness values are stored correspondingly; common luminous intensity standard definition values are divided into multiple intervals; a standard definition luminous intensity interval value of the luminous intensity of the present environment is determined; a brightness value of a present screen is calculated according to the interval value of the luminous intensity value of the present environment and the stored screen brightness values; the screen brightness is adjusted according to the brightness value of the present screen. According to the method, customized setting demands of users can be satisfied, change of the surrounding environment luminous intensity is made to satisfy a certain scope through setting sensitive intervals, adaptive brightness adjustment on the display screen is realized, and screen splash is avoided.

Description

technical field [0001] The invention relates to screen display technology, in particular to an adaptive screen brightness adjustment method and system. Background technique [0002] With the development of technology, all kinds of display screens are widely used in communication industry, household appliances industry, automobile industry and other fields, and the screen size is also becoming larger and larger. However, no specific definition is given for the screen brightness of the display screen. And the brightness of the screen is too bright or too dark will cause damage to human eyes. The existing screen brightness display system has at least the following problems: 1. The screen brightness cannot be customized; 2. When the screen brightness is set to "automatic", it cannot automatically adapt to the brightness needs of different users; 3. The screen brightness is set to "automatic". ", it is highly dependent on the acquisition precision and accuracy of the illuminance...
