(Signal output power,dBm).Pr refer to signal energy that antenna receives (Signal receiving power,
dBm).F is the frequency (MHz) of signal transmission.
Fig. 3 is refer to, it illustrates the graph of a relation of the brightness using RSSI estimated distances Yu display 110.By the song of curve
Knowable to rate change, the distance between lighting source 120 of display 110 and first parameter and the brightness settings parameter of display 110
It is negatively correlated.When the distance between lighting source 120 of display 110 and first increases, parameter adjustment controls 130 can be according to looking into
Table method or built-in data bank correspondingly adjust the brightness of the backlight of display 110, to improve the display effect of display 110.
In addition, refer to Fig. 4, it illustrates the graph of a relation of the brightness of the first lighting source 120 and the brightness of display 110.By curve
Curvature varying understands that the brightness of the first lighting source 120 is proportionate with the brightness settings parameter of display 110.When the first photograph
The rising angle in Mingguang City source 120 is fixed or illumination direction is fixed, and the distance between lighting source 120 of display 110 and first
In the case of unchanged, when only changing the brightness of the first lighting source 120, parameter adjustment controls 130 can be according to look-up table or interior
The data bank built correspondingly adjusts the brightness of the backlight of display 110, to improve the display effect of display 110.
The disclosed regulating system and method applied to display of the above embodiment of the present invention, using WiFi,
The convenient wireless distance finding method of the Wireless LANs such as Bluetooth or ZigBee offer, estimation display and surrounding environment
The distance between lighting source parameter and the display setting for adjusting display, therefore display need not add extra OPTICAL SENSORS
