Detailed Description

The following further explains the specific embodiments of the present invention with reference to the drawings:

the resolution of the display in this embodiment is preferably 1920x1080, and the preferred model is 9990DNBL 320H-01.

The controller of the main control module in this embodiment is preferably model RK 3288K.

In this embodiment, the LED lighting module preferably uses SMD5050 packaged lamp beads, and preferably adopts a cascade mode of 3 parallel 12 strings.

In the embodiment, the illumination sensing module preferably adopts a sensor with the model number of ALS-PDIC15-21C as the acquisition of the ambient light brightness.

As shown in fig. 1, a total reflection type display device includes a display 100, an LED lighting module 200, a main control module 300, an illumination sensing module 400, a signal access module 500 and a power module 600, where the main control module 300 includes a display output interface 301 and an LED driving interface 302, the display output interface 301 is connected to the display 100, the LED driving interface 302 is connected to the LED lighting module 200, the LED driving interface 302 is used to control the brightness of the LED lighting module 200, the illumination sensing module 400 is used to sense the brightness of ambient light, the signal access module 500 is used to connect a signal source 700, and send data in the signal source 700 to the main control module 500, and the power module 600 is used to connect an external power supply 800 for supplying power to various parts of the device. The main controller 300 obtains a signal of an external signal source 700 through the signal input interface 500, is connected to the display 100 through the display output interface 301 after internal processing, analyzes the input signal and displays the analyzed input signal to the display 100, and meanwhile, the main controller 300 obtains the intensity of ambient light through the illumination sensing module 400, and controls the brightness of the LED lighting module 200 through the LED driving interface 302 after internal conversion.

When the device is placed in a bright environment, the value of the ambient brightness returned by the illumination sensing module 400 is large, and after the large brightness value is returned to the main control module 300, the main control module 300 sends an instruction to the LED driving interface 302 to turn off the LED lighting module 200, and under the specified action, the LED lighting module 200 is turned off. Under the irradiation of the ambient light with bright surroundings, under the characteristic action that the display 100 reflects all incident visible light, the content transmitted to the display 100 through the display output interface 301 is illuminated by the reflected light, and thus viewed by the observer; in this case, since the display has no backlight unit and the LED lighting module 200 is in the off state, the power consumption of the entire device at this time is the sum of the power consumptions of the main control module 300 and the display 100, and the power consumption of the entire device does not exceed 3W in the case where the device normally operates.

When the device is placed in a dark ambient environment, the ambient brightness value returned by the illumination sensing module 400 is relatively small, and after the relatively small brightness value is returned to the main control module 300, the main control module 300 sends an instruction for turning on the LED lighting module 200 to the LED driving interface 302, and under the specified action, the LED lighting module 200 is turned on, and the smaller the ambient brightness is, the larger the brightness sent by the LED lighting module 200 is, and the LED lamps of the LED lighting module 200 are designed to uniformly emit light toward the surface of the display 100; under the illumination of the light of the LED illumination module 200, the content transmitted to the display 100 through the display output interface 301 is illuminated by the reflected light under the characteristic that the display 100 reflects all incident visible light, so that the viewer sees the content. In this case, since the display has no backlight unit, the LED lighting module 200 is in an on state, the power consumption of the entire device at this time is the sum of the power consumptions of the main control module 300, the display 100, and the LED lighting module 200, and the power consumption of the entire device does not exceed 6W when the LED lighting module 200 is brightest.

The utility model relates to a total reflection-type display device is different from prior art: by utilizing the light reflecting characteristic of the total reflection screen and the characteristic that a backlight unit is not needed and utilizing ambient light and an active light source to provide illumination required by display for the display, the purpose of normally displaying the required displayed content under the condition of low power consumption is realized, and the energy consumption is reduced.
