Optical display unit has plasma display, electric moistening display, electrochromic display device (ECD), electrophoretic display device (EPD), Organic Light Emitting Diode
Display etc..OLED display does not need backlight module, principle of luminosity and common inorganic compared to traditional liquid crystal display
The principle of luminosity of light emitting diode (LED) device is similar, i.e., deposits very thin organic material between two electrodes, have to this
Machine luminescent material, which passes to direct current, makes it shine.Since OLED display eliminates backlight module, OLED display
Can be made lighter, thinner, visible angle is bigger, and can save significantly on electric energy, therefore OLED display gradually at
For the mainstream of display field.
One important performance characteristic of display is display brightness.Display when in use, locating for external environment
In generally can all have the influence of environment light (such as illumination light), mirror-reflection phenomenon can occur for display screen, in addition to display itself
Brightness outside, also have the eyes that a large amount of reflection light enters user, affect user's viewing experience.In general, in room
When intraoral illumination, generally between 100~500lux, picture quality is slightly deteriorated illumination, but the reflection of display panel compared with
It is obvious.Only under dim indoor light, i.e. for illumination between 0~100lux, display can just show preferable face
Color, contrast, gray scale etc..Therefore, in order to improve the viewing experience of user, need to carry out the adjusting of display brightness, while
Improve display brightness while, improve the temperature of display, further improve the energy consumption of display, thus it is proposed that
A method of it reducing display energy consumption and promotes its brightness.

Brightness be adjusted；
S4: while according to the personnel location information of acquisition, it determines in the reflection light through indicator screen reflection in illumination light
The pixel position of indicator screen where being able to enter the reflection light of human eye, and using the pixel position determined as need
The compensation position for carrying out luminance compensation, it is right according to the current brightness value of collected illumination light and the corresponding relationship of compensation rate
The brightness for the pixel in compensation position determined compensates；
S5: the display interior temperature detected according to S1 determines if beyond given threshold, beyond carrying out after threshold value to it
Cooling and heat dissipation.
Preferably, it is detected in the step S1 by environment monitoring module, environment monitoring module includes illumination sensing
Device, temperature sensor and two infrared sensors, the optical sensor and infrared sensor are respectively positioned on the outer wall of display screen,
Temperature sensor is located at the inside of display screen.
Preferably, the eye position of human body is estimated by the human height that two infrared sensors detect, and is calculated
Position of human eye information out.
Preferably, the current collected position of human eye information of the basis is determined in illumination light through display screen reflection
The pixel position of display screen where being able to enter the reflection light of human eye in reflection light.
Preferably, the inside of the display is equipped with the light emitting source of multiple rectangular arrays arrangement, for indicator screen
On pixel compensate.
Preferably, the heat dissipation in the step S5, by changing heat dissipation hole number and extraneous sky on display casing
Flow of air radiates.
Preferably, pass through the size of current of indicator screen backlight in the step S3 to realize to indicator screen
The adjusting of brightness.
The present invention light intensity extraneous by detection, is in real time adjusted brightness of display screen, so that human eye is being watched
It is more comfortable when indicator screen, while preventing in display when care intensity is big, brightness is excessively high, and energy consumption is high；
Simultaneously can human eye watch when, in extraneous illumination light through display screen reflection reflection light in be able to enter human eye
The brightness of the pixel of display screen compensates where reflection light, improves the display effect that display shows image；
While improving brightness, the calorific value of light emitting source is increased, by being adjusted to display interior temperature, reduces temperature
Spending height causes the energy consumption of display screen internal component to increase.
