Problems solved by technology

[0002] At present, the display requires the user to manually turn off, turn on, sleep and wake up, which is inconvenient. Therefore, many people leave the display in a short time and within a short distance, that is, they do not turn off the display or put it in a sleep state, which wastes power; and the existing display The brightness needs to be adjusted manually. The manually adjusted brightness is not necessarily the healthiest brightness for the human body, and may be harmful to the user's eyes.

Embodiment Construction

[0007] refer to figure 1 , an energy-saving display, including a microcontroller, characterized in that: the input end of the microcontroller is connected to a sensing module, and the output end is connected to a display backlight and a Scaler, and the display backlight and the Scaler are output to the display module.

[0008] The sensing module includes an infrared sensor and a light sensor.

[0009] The above infrared sensor senses the distance between the human body and the display by receiving the infrared emitted by the built-in infrared emitting diode of the display and reflected back by the human body and generates an infrared sensing signal. The above microcontroller receives the infrared sensing signal and generates a corresponding display command , the display backlight and the Scaler execute corresponding display instructions, and the display module turns on or off the display.

[0010] The light sensing module senses the brightness of white light in the surroundin...

Abstract

The invention relates to an energy-saving display, which comprises a microcontroller, and is characterized in that: the input end of the microcontroller is connected with a sensor module, while the output end is connected with a display backlight and a Scaler which output to a display module. The display can be automatically turned on or turned off according to a distance between a human body and the display, and is convenient and energy-saving; and the brightness of the display can be automatically adjusted according to the white light brightness in the ambient environment, so the energy consumption of the display is reduced and the eyes of a user are protected.

Description

technical field [0001] The invention relates to an energy-saving display, which is suitable for the field of liquid crystal displays. Background technique [0002] At present, the display requires the user to manually turn off, turn on, sleep and wake up, which is inconvenient. Therefore, many people leave the display in a short time and within a short distance, that is, they do not turn off the display or put it in a sleep state, which wastes power; and the existing display The brightness needs to be adjusted manually. The manually adjusted brightness is not necessarily the healthiest brightness for the human body, and may be harmful to the user's eyes. Contents of the invention [0003] The object of the present invention is to provide a display with human body sensing function, which can turn on and off the display according to the distance between the human body and the display, automatically adjust the brightness of the display according to the brightness of white lig...
