Problems solved by technology
However, outdoor display screens are easily affected by the external environment, especially the external brightness.
For example, when the intensity of sunlight is high, if the brightness of the display screen is not enough, the display content of the display screen will not be clear.
When the brightness of the sun is low or at night, if the brightness of the display is high, it will dazzle the audience and waste power

Embodiment Construction
[0023] The display screen system of the present invention will be further described below with reference to the figures.
[0024] See figure 1 , the display screen system 100 of the embodiment of the present invention includes a display screen 110 , a solar panel 120 , a voltage reader 130 , a central processing unit 140 and a brightness controller 150 .
[0025] The display screen 110 is a liquid crystal display screen or an LED display screen. The display screen 110 is used to display various information, such as weather, real-time traffic conditions, maps and the like.
[0026] The solar panel 120 generates a DC voltage according to the intensity of external sunlight.
[0027] The voltage reader 130 is connected to the solar panel 120 . The voltage reader 130 is used for receiving the DC voltage of the solar panel 120 . In this embodiment, the voltage reader 130 converts the DC voltage value of the solar panel 120 into a DC voltage value represented by a digital signal ...

A display screen system comprises a display screen for displaying information, a solar panel for generating a direct-current voltage according to the illumination intensity of sunlight, a voltage reader which is connected with the solar panel and used for receiving the direct-current voltage output by the solar panel, a central processing unit connected with the voltage reader and used for receiving the voltage value of the voltage reader and generating control signals according to the voltage value output by the voltage reader and a brightness controller connected with the central processing unit and used for receiving the control signals and controlling the brightness of the display screen according to the control signals. The display system can control the brightness of the display screen automatically according to the output voltage of the solar panel so as to achieve energy-saving and carbon-reducing effects. The invention further provides a method for controlling the brightness of the display screen.
Description
technical field [0001] The invention relates to a display screen system, in particular to a display screen system capable of automatically controlling the brightness of the display screen and a method for controlling the brightness of the display screen. Background technique [0002] With the application of display screens becoming more and more extensive, various display screens have been applied to application fields such as outdoor billboards and advertisements to display various information. However, outdoor display screens are easily affected by the external environment, especially the external brightness. For example, when the intensity of sunlight is high, if the brightness of the display screen is not enough, the displayed content of the display screen will not be clear. When the brightness of the sun is low or at night, if the brightness of the display screen is high, it will dazzle the viewers and waste electric energy at the same time. Contents of the invention...
