Problems solved by technology

[0003] The application scenarios of LED display screens are very diverse. When it is applied to an environment with strong light, the picture will appear dim and cannot be seen clearly; when it is applied to an environment with low light, the picture will appear excessive. Thereby forming a strong stimulus to the viewer's vision and causing discomfort

Embodiment Construction

[0016] refer to figure 1 , a light intensity self-adaptive LED display screen proposed by the present invention, comprising: a light intensity sensor, a brightness control module, a chromaticity control module, a video data processing module, a drive module and an LED dot matrix.

[0017] The light intensity sensor is used to detect the ambient light intensity in real time.

[0018] The brightness control module is connected with the light intensity sensor, which can make the LED display screen adapt to the target brightness of the ambient light intensity according to the light intensity detected by the light intensity sensor, and generate a brightness control signal.

[0019] The chromaticity control module is connected with the luminance control module, which adjusts the preset chromaticity according to the target luminance to generate a target chromaticity suitable for the target luminance. When the brightness value is large and the saturation of the chroma is low, the col...

Abstract

The invention provides a light intensity self-adaptive type LED display screen. The light intensity self-adaptive type LED display screen comprises a light intensity sensor, a brightness control module, a color control module, a video data processing module, a driving module and an LED dot matrix, wherein the brightness control module is connected with the light intensity sensor, the color control module is connected with the brightness control module, the video data processing module is connected with the color control module, and the driving module is connected with the brightness control module, the video data processing module and the LED dot matrix. According to the light intensity self-adaptive type LED display screen, due to the facts that the light intensity of the environment is detected in real time, and the brightness of the display screen is adjusted according to the light intensity, the problem that the display screen is excessive bright or excessive dark can be solved; due to the fact that the color is adjusted to adapt to the brightness, the problem that the brightness and the color of the display screen are not matched can be solved.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to a light intensity self-adaptive LED display screen. Background technique [0002] The LED display screen is composed of small LED module panels. The LED display screen can be used to display various information such as text, images, videos, and video signals. As a visual information display device, LED display has the characteristics of variable information, rich colors, wide adjustable range of brightness, low ICBC, high reliability, and long life. It has played an increasingly important role in the field of modern display technology. role. [0003] The application scenarios of LED display screens are very diverse. When it is applied to an environment with strong light, the picture will appear dim and cannot be seen clearly; when it is applied to an environment with low light, the picture will appear excessive. Thereby forming a strong stimulus to the viewer's visi...
