[0026] In order to make the above-mentioned objects, features and advantages of the present invention more understandable, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from this description, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0027] like Figure 1 , Figure 2 As shown, the present invention discloses a novel multi-level and stereoscopic display device, which comprises: a housing 1, the housing 1 is provided with a mounting groove 10, a partition plate 11 is provided in the mounting groove 10, and a plurality of light-transmitting grooves 110 are formed on the partition plate 11;

[0028] A PCB 2 is installed on one side of the partition plate 11, and the PCB 2 is provided with a functional light source, and the spatial position of the functional light source corresponds to the light-transmitting groove 110;

[0029] A functional film 3, a light guide plate 4 and a surface film 5 are sequentially installed on the other side of the partition plate 11. The functional film 3 and the surface film 5 are both light-transmitting films. A functional pattern composed of multiple gratings and / or printed images is arranged on the functional film 3. A background light source 40 is installed on the side of the light guide plate 4. The background light source 40 performs unilateral / multi-sided side lighting on the light guide plate 4.

[0030] In particular, the first part of the functional pattern is a pattern composed of multiple gratings, and the second part is a printed image, which can be combined to achieve better functional icon display;

[0031] Background display: when the device is in standby and not displaying, the background light source 40 is activated and illuminates the light guide plate 4 sideways;

[0032] Functional display: when the device is in the start-up display state, the functional light source of the PCB2 is started and illuminates the functional film 3 and provides a three-dimensional display function through the multiple gratings.

[0033] It should be noted that the surface film 5 is a fully transparent / semi-transparent film, the functional film 3 is a white or transparent film, and the material of the surface film 5 and the functional film 3 is any one of PET soft film, PC soft film, and PMMA. The front or back of the surface film 5 can be formed with frosted texture, and both sides of the functional film 3 are smooth. The pcb2 is provided with a corresponding main control module, power module, control module, dimming module and communication module. The functional light source is a plurality of independently controllable LED lamp beads arranged on the pcb2, which are anti-cross-light through the light-transmitting groove 110. Furthermore, the background light source 40 can be a plurality of monochromatic lamp beads or RGB light strips, and the RGB light strips are equipped with corresponding control ICs to achieve a running water horse racing effect.

[0034] Specifically, the background light source 40 includes a plurality of independently controllable lamp beads. When the background display is executed, the lamp beads are turned on and off and the colors and brightness are changed according to a preset program.

[0035] Specifically, a background pattern is formed on the surface film 5 , and the background pattern is formed on the surface film 5 by laser engraving or printing. In the background display, the background pattern appears under lighting, and the background pattern may be a starry sky background pattern or other decorative background patterns.

[0036] Specifically, the display device can realize human-computer interaction in a variety of ways. Any one or more of the functional film 3, the surface film 5 and the PCB 2 are provided with a touch circuit, and the touch circuit is used to provide a touch function. The touch circuit is capacitive or resistive. For example: 1. A key assembly is configured, and the key assembly is arranged on the pcb2 or the shell 1, and the key assembly is electrically connected to the pcb2; 2. A touch circuit is printed on one side of the functional film 3, and the touch circuit is electrically connected to the pcb2. The touch circuit is used to provide a touch function, and the touch circuit is capacitive or resistive; 3. The surface film 5 is provided with a first touch area, and a touch circuit is printed in the touch area, and the touch circuit is electrically connected to the pcb2, and the touch circuit is used to provide a touch function, and the touch circuit is capacitive or resistive; 4. The pcb2 is provided with a second touch area, and the second touch area is provided with a touch circuit, and the touch circuit passes through the partition plate 11 and is connected to the functional film 3, and the touch circuit is capacitive or resistive; 5. The pcb2 is provided with a spring touch assembly, and the spring touch assembly is configured with a plug-in lamp bead as a backlight, and the force-bearing end of the spring touch assembly is connected to the functional film 3 or is arranged on the shell 1.

[0037] The touch circuit is a conventional capacitive or resistive touch circuit. The touch forms of the touch circuit include: single-point touch and sliding touch. When the touch circuit is capacitive, it forms a trigger area, which is painted with conductive ink, and the trigger area corresponds to the position of the corresponding key pattern or key text. The electrical connection of the electrical components can be achieved through flexible FPC and wiring terminals.

[0038] When in use, if the user triggers the display device through a button or touch, the background display will be switched to the function display.

[0039] In the functional display, the functional light source of the PCB is started and illuminates the functional film, during which the background light source is in an off or lighting effect control state, wherein the lighting effect control state is: the background light source performs lighting effect feedback according to the user's touch (i.e., the lighting changes according to the color change and change interval time, brightness change and change interval time, on and off and on and off interval time of the preset light group) to provide dynamic lighting feedback effects and enhance the three-dimensional effect, such as: generating a water drop ripple lighting effect centered on the touch point.

[0040] Furthermore, the functional light source illuminates the functional film so that the functional pattern composed of the grating is illuminated, and the three-dimensional dynamic display of the functional pattern is realized by modulating the light using the grating. The modulation can be a running horse-drawn flowing lighting of the LED lights corresponding to the spatial position of the functional pattern. The running horse-drawn flowing lighting is to turn the LED lights on and off in order of position or to control the brightness of the LED lights to change in sequence (decreasing or increasing) or to control the color of the LED lights to change in sequence.

[0041] To sum up, the display device performs an independent background display in standby mode to avoid revealing the specific outline of the internal digital tube or the light-transmitting slot. At the same time, the running and flowing dynamic effect of the background display can be achieved through light control to meet the consumers' requirements for aesthetics and atmosphere; in the startup state, the functional pattern on the functional film is displayed to meet the consumers' usage needs and provide a three-dimensional functional pattern display effect, and the visual effect is further enriched by adjusting the on and off, color and brightness changes of the LED lights.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] The above-described embodiments only express one or more implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
