I.e., first side 441 may be the entrance port through which the target light is directed toward item card 400. The first side 441 may be any one of a plurality of sides in the material deck 400. For example, when the material tablet 400 is a rectangular parallelepiped, the first side 441 may be any one of a lower side, an upper side, a left side, and a right side. In some embodiments, the first side 441 may be the lower side when the material tablet 400 is positioned on the upper side of the display screen 200. I.e., the light emitting unit 600 may be located at the lower side of the material tablet 400. At this time, the light emitting unit 600 may be positioned between the material tablet 400 and the display screen 200.

The sides of the side 440 of the material card 400 other than the first side 441 are other sides 442. The other side 442 may be connected to the first side 441. The other side surfaces 442 may be covered with a light-shielding ink to prevent the target light emitted from the light-emitting unit 600 from being emitted through the other side surfaces 442, so as to prevent the target light from damaging the eyes of the user.

The light emitting unit 600 may be installed inside the case 100. Specifically, the light emitting unit 600 may be installed in the receiving cavity 140 formed by the first case 110 and the second case 120. The light emitting unit 600 may be located at any side of the material tablet 400. In some embodiments, the light emitting unit 400 may be located on a side of the material tablet 400 near the display screen 200. I.e., the light emitting unit 600 may be located between the material tablet 400 and the display screen 200. In some embodiments, light emitting unit 600 may also be located on other sides of material tablet 400, such as, for example, the top, left, right, etc. The light emitting unit 600 may include a light emitter 620. In some embodiments, the light emitting unit 600 may further include a light diffusion plate 640.

Light 620 may operate to direct different colored target lights toward material cards 400 to illuminate material cards 400. As previously mentioned, the material tablet 400 may be a transparent material. When light 620 emits target light of different colors, the target light is directed to material cards 400 and causes material cards 400 to appear in a color consistent with the color of the target light.

In some embodiments, the light 620 may include at least one RGB lamp 622 and a driving circuit 624. The RGB lamp 622 is an LED lamp that images by the intersection of the three primary colors of the R lamp 622-1, the G lamp 622-2, and the B lamp 622-3, and the ratio of each component of the R lamp 622-1, the G lamp 622-2, and the B lamp 622-3 is adjusted by controlling the brightness of each component of the R lamp 622-1, the G lamp 622-2, and the B lamp 622-3, so that the RGB lamp 622 represents different colors. As previously described, light 620 may be located on one side of material tablet 400. The number of RGB lamps 622 may be one or more. When the number of the RGB lamps 622 is plural, the plural RGB lamps 622 may be distributed along the extending direction of the first side 441 of the material tablet 400. For example, when the first side 441 is the lower side of the material tablet 400, the plurality of RGB lamps 622 may be linearly distributed along the extending direction of the first side 441 of the material tablet 400, for example, linearly distributed along the width direction. Of course, when the thickness of the material tablet 400 is relatively thick, the plurality of RGB lamps 622 may be arranged in a rectangular pattern along the first side 441 of the material tablet 400. The number of RGB lights 622 may be determined according to the width of the material cards 400 (i.e., the extension length of the first side 441), the viewing angle of each RGB light 622, and the distance between the RGB lights 622 and the material cards 400, so as to ensure that the target light emitted by at least one RGB light 622 can cover all the identification information on the material cards 400. The wider the width of the material tablet 400 (i.e., the extended length of the first side 441), the greater the number of RGB lights 622. Specifically, the wider the identification information on the material tablet 400, the greater the number of RGB lights 622. The smaller the viewing angle of each RGB lamp 622, the greater the number of RGB lamps 622. The farther the RGB lights 622 are from the material deck 400, the greater the number of RGB lights 622. The distance between the RGB lights 622 and the material tablet 400 may be determined according to the viewing angle of each RGB light 622.

The driver circuit 624 may be communicatively coupled with the at least one RGB lamp 622 and the control device 800. Specifically, the driving circuit 624 may be electrically connected with the at least one RGB lamp 622 and the control device 800. The control device 800 may be a circuit board. In some embodiments, the driver circuitry 624 may be circuitry disposed on the circuit board 800. In some embodiments, the driving circuit 624 and the control device 800 may be two circuit boards arranged separately. In some embodiments, the at least one RGB lamp 622 may be soldered on a circuit board on which the driving circuit 624 is located, and electrically connected to the driving circuit 624. The driving circuit 624 may drive the at least one RGB lamp 622 to emit the target light under the control of the control device 800, and the control device 800 may control the light emitting brightness and color of the target light of the at least one RGB lamp 622.

In some embodiments, at least one RGB lamp 622 may be replaced with an LED display panel. The driving circuit 624 may be electrically connected to the LED display panel and drive the LED display panel to display a corresponding target image. The colors of different target images are different. When the LED display panel displays the target images of different colors, the LED display panel may emit target light in accordance with the colors of the target images.

In some embodiments, the light emitting unit 600 may further include a light diffusion plate 640. A light diffusion plate 640 may be positioned between the material brand 400 and the light emitter 620 to diffuse the target light. The light diffusion plate 640 may have optical patterns thereon for strong light diffusion. The target light emitted from the light emitter 620 is optically diffused by the light diffusion plate 640 and then transmitted to the material cards 400 to be uniformly illuminated, so that the material cards 400 are uniformly illuminated.

In some embodiments, the display apparatus 001 may further include a control device 800. The control device 800 may store data or instructions for performing the color control method for the material cards described herein and may execute or be used to execute the data and/or instructions. The control device 800 may be mounted inside the housing 100. Specifically, the control device 800 may be installed in the accommodating cavity 140 formed by the first housing 110 and the second housing 120. Control device 800 may be communicatively coupled to display screen 200 and light 620. The communication connection may be an electrical connection. The control device 800 may acquire the display image of the display screen 200, and control the color of the target light emitted by the light 620 based on the color of the display image, so that the color of the target light is consistent with the color of the display image, thereby causing the material tablet 400 to display the color consistent with the display image. When the display screen 200 plays pictures, advertisements or videos, the material board 400 may emit light effects corresponding to the background color of the display image to form an interactive effect. When the display images of the display screen 200 are switched, the light colors of the material cards 400 are simultaneously switched to correspond. When the display images are switched quickly, the material tablet 400 can show a horse race light effect along with the switching direction of the display images.

The control device 800 may include a hardware device having a data information processing function and necessary programs necessary for driving the hardware device to operate. Of course, the control device 800 may be only a hardware device having a data processing capability, or only a program running on a hardware device. In some embodiments, the control apparatus 800 may include a mobile device, a tablet computer, a laptop computer, an in-built device of a motor vehicle, or the like, or any combination thereof. In some embodiments, the control apparatus 800 may be a device having a positioning technology for positioning the position of the display device 001. As shown in fig. 5, the control apparatus 800 may include at least one processor 820 and at least one storage medium 830.

The storage medium 830 may include a data storage device. The data storage device may be a non-transitory storage medium or a transitory storage medium.

The instructions are computer program code that may include programs, routines, objects, components, data structures, processes, modules, etc. that perform the color control methods for the tiles provided in this specification.

The at least one processor 820 may be communicatively coupled to the at least one storage medium 830, the display screen 200, and the drive circuitry 624. The communication connection may be an electrical connection. The at least one processor 820 is configured to execute the at least one instruction set. When the control device 800 is operated, the at least one processor 820 reads the at least one instruction set and executes the color control method of the material cards provided in the present specification according to the instruction of the at least one instruction set. The processor 820 may perform all the steps involved in the color control method of the material cards. Processor 820 may be in the form of one or more processors, and in some embodiments, processor 820 may include one or more hardware processors, such as microcontrollers, microprocessors, reduced Instruction Set Computers (RISC), application Specific Integrated Circuits (ASICs), application specific instruction set processors (ASIPs), central Processing Units (CPUs), graphics Processing Units (GPUs), physical Processing Units (PPUs), microcontroller units, digital Signal Processors (DSPs), field Programmable Gate Arrays (FPGAs), advanced RISC Machines (ARM), programmable Logic Devices (PLDs), any circuit or processor capable of executing one or more functions, or the like, or any combination thereof. For illustrative purposes only, only one processor 820 is depicted in the present description in control device 800. It should be noted, however, that the control device 800 may also include multiple processors 820, and thus, the operations and/or method steps disclosed in this specification may be performed by one processor as described in this specification, or may be performed by a combination of multiple processors. For example, if in this specification the processor 820 of the control device 800 performs steps a and B, it should be understood that steps a and B may also be performed by two different processors 820, either jointly or separately (e.g., the first processor performs step a, the second processor performs step B, or both the first and second processors perform steps a and B).

Fig. 6 shows a flowchart of a method P100 for controlling the color of a material card provided according to an embodiment of the present description. As described above, the control device 800 may perform the color control method P100 for the material cards described in this specification. Specifically, the processor 820 may read a set of instructions stored in its local storage medium and then execute the method P100 for controlling the color of a material card described herein according to the specification of the set of instructions. As shown in fig. 6, the method P100 may include:

s120: a display image of the display screen 200 is acquired.

The control device 800 may acquire the display image from the display screen 200 based on the electrical connection with the display screen 200. The control device 800 may acquire the display image in real time, or may acquire the display image when detecting that the display image changes.

S140: the color of the target light emitted by the light emitter 620 is controlled based on the color of the display image so that the color of the target light coincides with the color of the display image.

In some embodiments, the display image may be larger. The colors of the reality may be different for different regions of the displayed image. In order to make the actual color of the material card 400 consistent with the color displayed on the display screen 200, the control device 800 may make the color of the target light emitted by the light 620 consistent with the color of the target area near the material card 400 in the display image. The target area may be a portion of pixels in the display image near the material tablet 400, such as a row of pixels, for example, 2 rows of pixels, or even more, and so on. The size of the target area is related to the size of the display screen 200. The size of the target area may be a portion of the display screen 200, such as 1/2, 1/3, 1/4, etc.

When the display image displayed on the display screen 200 is switched or the display screen 200 plays a video, the control device 800 may obtain the display image of the display screen 200 at the current moment, and analyze the color distribution of the target area in the current display image using an analysis algorithm. The control device 800 may calculate and analyze the target proportions of the three primary colors of R, G, and B, i.e., the target proportions of red R, green G, and blue B, in the target region in the currently displayed image.

S144: based on the target ratio, the light 620 is controlled to emit the target light in conformity with the target area color.

Specifically, step S144 may include:

s144-2: based on the target ratio, a target luminance of the respective colors R, G, B in each RGB lamp 622 of the at least one RGB lamp 622 is determined.

As previously mentioned, the luminary 620 may comprise at least one RGB lamp 622. The RGB light 622 may include R, G, B three primary color lights, namely R light 622-1, G light 622-2, B light 622-3. The control device 800 may calculate the target brightness of each color of R, G, B in each of the at least one RGB lamp 622 based on the target ratios of the three primary colors of R, G, B analyzed in step S142. The higher the proportion of colors, the greater the brightness.

S144-4: and generating a target control signal corresponding to the target brightness.

The control device 800 may generate corresponding target control signals based on the target luminances of the respective R, G, and B colors, and output the signals to the driving circuit 624.

S144-6: based on the target control signal, the control drive circuit 624 drives the at least one RGB lamp 622 to emit the target light in accordance with the target area color.

The control device 800 outputs the target control signal to the driving circuit 624 to control the driving circuit 624 to drive the R lamp 622-1, the G lamp 622-2, and the B lamp 622-3 in each RGB lamp 622 respectively according to the target brightness of each color of R, G, and B, so as to change the color of the target light emitted by the RGB lamps 622 with the change of the display image, and simultaneously, the color of the material plate 400 can also change according to the color of the target light, so that the color of the material plate 400 is consistent with the color of the display image displayed by the target area of the display screen 200 close to the material plate 400, and the color of the material plate 400 can change synchronously with the display image of the display screen 200.

To sum up, according to the display device 001 and the color control method P100 of the material plate provided in this specification, the material plate is made of a transparent material, and the light-emitting body is disposed on one side of the material plate to emit target lights of different colors to the material plate to illuminate the material plate, so that the material plate displays different colors under the irradiation of the target lights. The control device can control the color of the target light emitted by the light-emitting body according to the color of the display image of the display screen, so that the color of the target light is consistent with the color of the display image, and the material plate can display the color consistent with the display image. When the display screen plays pictures, advertisements or videos, the material board at the top emits light effects corresponding to the background color of the displayed images to form an interactive effect. When the display images of the display screen are switched, the light colors of the material cards correspond with the switching. When the display images are switched rapidly, the material board can show horse race lamp effect along with the switching direction of the images. According to the display device and the color control method of the material board, the material board emits light with the same color as the display image, so that the material board can be clearly displayed under any condition, and the problem that the material board cannot be seen clearly due to the fact that a dark area is formed under the illumination of a display screen is avoided. Meanwhile, the display equipment and the color control method of the material cards provided by the specification can enable the material cards to be more striking and attractive, and increase the technological sense, interestingness and attractiveness while increasing the identification degree of the material cards.
