[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1.

When a finger or other touch operation contacts the adjustable transmittance glass, there is pressure on the lower side, and the upper infrared light strip and the lower infrared light strip as well as the left infrared light strip and the right infrared light strip face each other are blocked. The touch position is identified by the built-in controller, or the touch is completed by the infrared emission and receiving functions of the infrared sensor. When the touch operation covers a sensor so that it receives the reflected infrared light, the touch is triggered, and the touch position is known by the built-in controller. Through these two touch methods, large-size LED display screens can realize interactive touch, which is suitable for scenes with more interactive needs such as teaching and family.

[0025] 2. Compared with the traditional method of adjusting the brightness which may cause color distortion due to loss of grayscale of the LED display, the invention uses the setting of adjustable transmittance glass to change the transmittance of the adjustable transmittance glass by controlling the capacitor to change the voltage through the controller. The transmittance adjusts the overall display brightness to achieve a soft picture effect, which is more suitable for long-term viewing, thereby making the invention suitable for application in scenarios such as home and teaching.

[0026] 3. The invention arranges the focusing point and the focusing cavity on the infrared lamp cover, so that the infrared light emitted by the lower infrared lamp bead, the left infrared lamp bead, the right infrared lamp bead and the upper infrared lamp bead are more concentrated. When the user touches the screen, the blocking position of the shooting point can be determined more accurately and the touch is more sensitive. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] Example 1

[0037] See also Figure 1-5 An embodiment of the present invention is as follows: an interactive, writable, touch-sensitive, eye-protecting glass mirror LED display device, comprising a lamp board 3 and a controller 12, the model of the controller 12 is KY101-1, and an adjustable transmittance glass 7 is installed on the front end surface of the lamp board 3. The adjustable transmittance glass 7 appeared in the 2010s, and it has been more than five years. During this period, this technology has matured. This glass product is composed of a film covered with fine light particles sandwiched in the middle of the glass. When no electrical load passes through the film, these particles will disperse and absorb light, making the glass darker. When the electrical load is loaded, these particles will be arranged in rows to let light pass through. However, this technology is rarely used in display devices. It is basically achieved by adjusting the brightness of electronic equipment, but the grayscale of the LED display may be lost to cause color distortion. The controller 12 controls the capacitor 13 to change the voltage, so that the transmittance of the adjustable transmittance glass 7 changes.

[0038] Furthermore, the upper end, one side, the other side and the lower end of the light board 3 are respectively installed with an upper infrared light bar 2, a right infrared light bar 4, a left infrared light bar 5 and a lower infrared light bar 6. The upper infrared light bar 2 and the lower infrared light bar 6 are opposite to each other, and the left infrared light bar 5 and the right infrared light bar 4 are opposite to each other. The upper infrared light bar 2, the right infrared light bar 4, the left infrared light bar 5 and the lower infrared light bar 6 are fixed to the light board 3 by a fixing part 601.

[0039] Further, the input end of the controller 12 is connected to the output ends of the lower infrared lamp bead 604, the left infrared lamp bead 8, the right infrared lamp bead 9 and the upper infrared lamp bead 10, the input end of the controller 12 is also connected to the output end of the brightness sensor 11 (model APDS-9005-020), and the output end of the controller 12 is connected to the input end of the capacitor 13;

[0040] The controller 12 is used to receive signals from the lower infrared lamp bead 604, the left infrared lamp bead 8, the right infrared lamp bead 9 and the upper infrared lamp bead 10 to determine the coordinates of the touch point. When the user touches the screen, pressing down at the touch point will block the upper infrared light bar 2 and the lower infrared light bar 6 and the left infrared light bar 5 and the right infrared light bar 4. The controller 12 identifies the X and Y coordinates of the touch position.

[0041] The brightness sensor 11 is used to provide the controller 12 with light information of the external environment. The brightness sensor 11 can sense the external brightness. When the external environment is too bright, the information is fed back to the controller 12. The controller 12 controls the voltage through the capacitor 13.

[0042] The capacitor 13 is used to receive control information from the controller 12 to adjust the voltage;

[0043] The lower infrared lamp bead 604 is used to emit infrared light to achieve infrared light reflection with the upper infrared lamp bead 10;

[0044] The left infrared lamp bead 8 is used to emit infrared light to achieve infrared light reflection with the right infrared lamp bead 9;

[0045] The right infrared lamp bead 9 is used to emit infrared light to achieve infrared light reflection with the left infrared lamp bead 8;

[0046] The upper infrared lamp bead 10 is used to emit infrared light to achieve infrared light reflection with the lower infrared lamp bead 604 .

[0047] Furthermore, the lower infrared light bar 6 includes an infrared lamp cover 603 and a focusing cavity 605. The infrared lamp cover 603 is located at the upper end of the focusing cavity 605. The infrared lamp cover 603 includes a focusing point 6031, and the focusing point 6031 and the center line of the focusing cavity 605 are located on the same vertical line. The focusing point 6031 and the focusing cavity 605 make the infrared light emitted by the upper infrared light bar 2, the right infrared light bar 4, the left infrared light bar 5 and the lower infrared light bar 6 more concentrated. When the user touches the screen, the determination of the blocking position of the shooting point is more accurate, and the touch is more sensitive. The focusing cavity 605 is set to a trapezoid, which is conducive to the concentration of light.

[0048] Furthermore, the lower infrared light strip 6 also includes an infrared base plate 602 and lower infrared lamp beads 604. A plurality of lower infrared lamp beads 604 are provided, and the plurality of lower infrared lamp beads 604 are arranged in a groove at the upper end of the infrared base plate 602. The infrared base plate 602 and the infrared lamp cover 603 are fixed by base plate buckles 6022 and lamp cover buckles 6032. The infrared base plate 602 also includes a light baffle 6021. The light baffle 6021 has the function of reflecting light, concentrating the diffused infrared light again, and reducing the impact on the light on both sides.

[0049] Furthermore, a back plate 1 is installed at the rear end of the lamp board 3 . The lamp board 3 includes an LED electric substrate 301 and LED lamp beads 302 . The LED lamp beads 302 are connected to the LED electric substrate 301 by soldering.

[0050] Example 2

[0051] See also Figure 6-7 An embodiment of the present invention is as follows: an interactive, writable, touch-sensitive, eye-protecting glass mirror LED display device, comprising a lamp board 3 and a controller 12, the model of the controller 12 is KY101-1, and an adjustable transmittance glass 7 is installed on the front end surface of the lamp board 3. The adjustable transmittance glass 7 appeared in the 2010s, and it has been more than five years. During this period, this technology has matured. This glass product is composed of a film covered with fine light particles sandwiched in the middle of the glass. When no electrical load passes through the film, these particles will disperse and absorb light, making the glass darker. When the electrical load is loaded, these particles will be arranged in rows to let light pass through. However, this technology is rarely used in display devices. It is basically achieved by adjusting the brightness of electronic equipment, but the grayscale of the LED display may be lost to cause color distortion. The controller 12 controls the capacitor 13 to change the voltage, so that the transmittance of the adjustable transmittance glass 7 changes.

[0052] Further, the controller 12 is bidirectionally connected to the infrared sensor 14 (module TCRT5000), the input end of the controller 12 is also connected to the output end of the brightness sensor 11 (model APDS-9005-020), and the output end of the controller 12 is connected to the input end of the capacitor 13;

[0053] The controller 12 is used to receive the touch signal of the infrared sensor 14 to determine the coordinates of the touch point. When the touch operation covers a certain infrared sensor 14 so that it receives the reflected infrared light, the touch is triggered, and the touch position is known through the built-in controller 12.

[0054] The brightness sensor 11 is used to provide the controller 12 with light information of the external environment. The brightness sensor 11 can sense the external brightness. When the external environment is too bright, the information is fed back to the controller 12. The controller 12 controls the voltage through the capacitor 13.

[0055] The capacitor 13 is used to receive control information from the controller 12 to adjust the voltage;

[0056] The infrared sensor 14 is used to emit and receive infrared light.

[0057] Furthermore, a back plate 1 is installed at the rear end of the lamp board 3 . The lamp board 3 includes an LED electric substrate 301 and LED lamp beads 302 . The LED lamp beads 302 are connected to the LED electric substrate 301 by soldering.

[0058] Working principle: When in use, when the user touches the adjustable transmittance glass 7 with his hand, there is a certain pressure on the bottom, because the upper infrared light bar 2 and the lower infrared light bar 6 are opposite to each other, and the left infrared light bar 5 and the right infrared light bar 4 are opposite to each other (due to the setting of the focusing point 6031 on the infrared lamp cover 603 and the focusing cavity 605, when the user touches the screen, the determination of the blocking position of the opposite shooting point is more accurate, and the touch control is more sensitive). Pressing down at the touched part will block the opposite shooting between the upper infrared light bar 2 and the lower infrared light bar 6 and the left infrared light bar 5 and the right infrared light bar 4, and the X, Y coordinates of the touched position are identified by the built-in controller 12; or the touch control is completed by the infrared emission and receiving functions of the infrared sensor 14. When the touch operation covers a certain infrared sensor 14 so that it receives the reflected infrared light, the touch control is triggered, and the touch position is known by the built-in controller 12; the touch operation is completed in these two ways, so that the large-size LED display screen can realize interactive touch control. When the user is watching the screen, the brightness sensor 11 can sense the external brightness. When the external environment is too bright, the information is fed back to the controller 12. The controller 12 controls the voltage through the capacitor 13. When the electrical load is loaded, the fine light particles are arranged in rows, and light passes through them normally, thereby improving the display brightness (purely adjusting the brightness may lose the grayscale of the LED display and cause color distortion). When the external environment is darker, the fine light particles disperse and absorb light, darkening the glass and making the picture soft.

[0059] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
