Description

Technical Field

[0001] This application relates to the field of displays, and more specifically to a novel LED display screen. Background Technology

[0002] As we all know, the color of the pixels in an LED display is formed by the superposition of red, green and blue LED lights. A typical laptop LED display has as many as hundreds of thousands of pixels.

[0003] Under normal circumstances, a few LED lights on an LED display screen may fail due to damage or aging from prolonged use, affecting the user experience. Moreover, if the entire display needs to be replaced due to the failure of a very small number of LED lights, the cost will be high. Summary of the Invention

[0004] This application is made in order to solve at least one of the above problems.

[0005] This application provides a novel LED display screen, which includes a housing, a display substrate, and a plurality of pixel substrates;

[0006] The display substrate is mounted on the housing;

[0007] The pixel substrates are evenly laid flat on the inner surface of the display substrate;

[0008] Each pixel substrate further includes a red LED, a green LED, a blue LED, and a pixel controller, wherein the pixel controller is connected to the red LED, the green LED, and the blue LED respectively, and is used to control their light emission and collect the physical state of each LED;

[0009] The display screen also includes a spotlight assembly;

[0010] The spotlight assembly is connected to each of the pixel controllers and installed inside the housing, and is used to control the emission of a red beam, a green beam, or a blue beam to a designated position on the pixel substrate according to the physical state.

[0011] The above embodiments have the following beneficial effects: When an LED on one of the pixel substrates malfunctions, the controller collects fault information such as the position and color of the malfunctioning LED, and controls the spotlight assembly to emit a red, green, or blue beam to the position of the malfunctioning LED, thus compensating for the missing pixel. Therefore, with this solution, even if an LED is damaged, it does not affect user operation, saving the user the cost of replacing the display.

[0012] In one possible implementation, the spotlight assembly includes a spotlight, an adjustment base, and a control board;

[0013] The adjustment seat is fixedly installed on the inner surface of the housing;

[0014] The spotlight is mounted on the adjustment base;

[0015] The control board is connected to each pixel controller, the spotlight, and the adjustment base respectively, and is used to control the adjustment base to move and control the spotlight to emit a beam of a specified color according to the input signal of the pixel controller.

[0016] The above embodiments have the following beneficial effects: After the controller collects fault information such as the position and color information corresponding to the faulty LED, it can control the adjustment base to adjust the beam emission angle so that the spotlight beam can directly reach the position of the faulty LED. This solution can correspond to several pixels by adjusting the spotlight beam emission angle, so that there is no need to arrange too many spotlights, saving costs and reducing the area occupied by the housing.

[0017] In one embodiment, the spotlight includes a lamp body and a transparent lampshade;

[0018] The lampshade contains a red light-emitting tube, a green light-emitting tube, and a blue light-emitting tube;

[0019] The control board is connected to the red, green, and blue LEDs and controls one of the LEDs to operate.

[0020] In one embodiment, the adjusting seat is a rotating seat, used to drive the spotlight to rotate in place, so as to adjust the emission angle of the spotlight.

[0021] The above embodiments have the following beneficial effects: In use, the rotating base can drive the spotlight to rotate, thus directing the beam to the designated position. This solution eliminates the need for the spotlight to move laterally or longitudinally within the housing space, increasing the design space within the housing and allowing for higher integration of the display.

[0022] In one embodiment, the display substrate is divided into a central region and a peripheral region;

[0023] The display screen also includes a reflective component, which is installed inside the housing and corresponds to the surrounding area, for directing the light beam emitted by the spotlight assembly toward the surrounding area via the reflective component.

[0024] The above embodiments have the following beneficial effects: Since it is difficult for a single or a few spotlights to simultaneously correspond to all pixels, especially the pixels in the surrounding area, the presentation effect of a single spotlight is not ideal due to the excessive emission angle. Therefore, for the pixels in the surrounding area, the light beam can be emitted to the reflective component, and the light beam can be emitted to the designated position in the surrounding area through the emission component, which can improve the presentation effect of the surrounding area.

[0025] In one possible implementation, the reflective assembly further includes a reflector.

[0026] Multiple reflectors are provided and are respectively installed around the periphery of the housing.

[0027] In one embodiment, the spotlight assembly is provided in multiple units, distributed on the inner surface of the housing;

[0028] Accordingly, the display substrate is divided into several sub-regions, and each of the spotlight components corresponds to a sub-region of the display substrate.

[0029] The above embodiments have the following beneficial effects: by setting multiple spotlight components, each spotlight component is responsible for its corresponding sub-area, thereby reducing the workload of each spotlight component.

[0030] In one embodiment, the number of spotlight assemblies is set to 3 to 6.

[0031] In one embodiment, the optimal distance between the spotlight assembly and the display substrate is 20–70 mm.

[0032] The above embodiments have the following beneficial effects: Experiments have shown that if the number of spotlight components is less than 20mm, due to the close distance and the limited illumination range of the spotlight components, a large number of spotlight components need to be arranged, which is very uneconomical and cumbersome to install; if the number of spotlight components is greater than 70mm, due to the greater distance, the intensity of the beam reaching the pixel point becomes weaker, affecting the actual visual experience.

[0033] In one embodiment, a plurality of the pixel substrates are provided with non-transparent baffles between each other.

[0034] The above embodiments have the following beneficial effects: the setting of the non-transparent baffle can reduce interference to other pixel positions when the light beam reaches the designated position. Attached Figure Description

[0048] To fully understand this invention, a detailed structure will be presented in the following description to illustrate the technical solution proposed by this invention. Optional embodiments of the invention are described in detail below; however, in addition to these detailed descriptions, the invention may have other embodiments.

[0049] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0050] like Figure 1 , Figure 2 and Figure 3 As shown, this application provides a novel LED display screen, which includes a housing 1, a display substrate 2, and a plurality of pixel substrates 3;

[0051] The display substrate 2 is mounted on the housing 1;

[0052] Several pixel substrates 3 are evenly laid on the inner surface of the display substrate 2;

[0053] Each pixel substrate 3 also includes a red LED, a green LED, a blue LED, and a pixel controller 31, wherein the pixel controller 31 is connected to the red LED, the green LED, and the blue LED respectively, and is used to control their light emission and collect the physical state of each LED.

[0054] The display screen also includes a spotlight assembly 4;

[0055] The spotlight assembly 4 is connected to each pixel controller 31 and installed inside the housing 1, and is used to control the emission of a red beam, a green beam, or a blue beam to a designated position on the pixel substrate 3 according to the physical state.

[0056] In this embodiment, the display substrate 2 is specifically installed in the receiving cavity of the housing 1; several pixel substrates 3 are laid flat on the inner surface of the display substrate 2 facing the housing 1. Each pixel substrate 3 includes a red LED, a green LED, and a blue LED. Various colors are ultimately presented through the color combination of these three types of LEDs. In addition to the above three types of LEDs, a pixel controller 31 is also included. The pixel controller 31 is specifically a microcontroller. The pixel controller 31 is electrically connected to the above three types of LEDs and is used to control the three types of LEDs to emit light of different intensities. It is also used to collect the physical state of each LED, including light color, brightness intensity, on / off state, and position information.

[0057] The spotlight assembly 4 is specifically installed inside the cavity of the housing 1. The spotlight assembly 4 is electrically connected to all the pixel controllers 31 and can obtain the on / off status and position information collected by all the pixel controllers 31 from the pixels.

[0058] When spotlight assembly 4 detects that a certain LED is off, it obtains the color and position of that LED's light and emits a red, green, or blue beam towards that designated location to compensate for missing pixels. Therefore, this solution ensures that even if an LED is damaged, it does not affect user operation, saving the user the cost of replacing the monitor.

[0059] like Figure 4 As shown, in one possible embodiment, the spotlight assembly 4 includes a spotlight 41, an adjustment base 42, and a control panel (not labeled);

[0060] The adjusting seat 42 is fixedly installed on the inner surface of the housing 1;

[0061] Spotlight 41 is mounted on adjustment base 42;

[0062] The control board is connected to each pixel controller 31, spotlight 41 and adjustment base 42 respectively, and is used to control the adjustment base 42 to move and control the spotlight 41 to emit a beam of a specified color according to the input signal of the pixel controller 31.

[0063] In this embodiment, the adjustment base 42 is specifically located at the center of the inner surface of the housing 1, and the adjustment base 42 has a turning function; the spotlight 41 is mounted on the adjustment base 42, and its emission angle can be adjusted as the adjustment base 42 turns; the control board is specifically a microcontroller, which can be installed at any position in the housing, and is used to receive all physical state information obtained by each pixel controller 31, and determine whether each LED is on or off based on the physical state information. If an LED is off during operation, it can be proven that it is damaged, and the adjustment base 42 is controlled to turn to adjust the emission direction of the spotlight 41 so that the beam of the spotlight 41 can directly reach the position of the faulty LED. This solution can correspond to several pixels by adjusting the emission angle of the spotlight 41, so that there is no need to arrange too many spotlights 41, saving costs, and reducing the area occupied by the housing 1.

[0064] In one embodiment, the spotlight 41 includes a lamp body and a transparent lampshade;

[0065] The lampshade contains red, green, and blue LEDs;

[0066] The control board connects to a red LED, a green LED, and a blue LED, and controls one of the LEDs to operate.

[0067] In this embodiment, a spotlight 41 integrates a red light-emitting tube, a green light-emitting tube, and a blue light-emitting tube. If a beam of light needs to be emitted, the control board can specify one of the emitted beams.

[0068] In one embodiment, the adjusting seat 42 is a rotating seat used to drive the spotlight 41 to rotate in place, so as to adjust the emission angle of the spotlight 41.

[0069] In this embodiment, the rotating base is fixed at the center of the housing 1 and can rotate around itself to drive the spotlight 41 to turn. In use, the rotating base can drive the spotlight 41 to rotate, so that the beam can reach the designated position. This solution eliminates the need for the spotlight 41 to move laterally or longitudinally within the housing 1, increasing the design space within the housing 1 and allowing for higher integration of the display.

[0070] like Figure 4 and Figure 5 As shown, in one possible embodiment, the display substrate 2 is divided into a central region and a peripheral region;

[0071] The display screen also includes a reflector 5, which is installed inside the housing 1 and corresponds to the surrounding area, for directing the light beam emitted by the spotlight assembly 4 to the surrounding area via the reflector 5.

[0072] In this embodiment, when it is necessary to direct the light beam toward the surrounding area, the light beam can be emitted to the reflective component 5. The light beam can be emitted to a designated position in the surrounding area through the emission component, thereby improving the presentation effect of the surrounding area.

[0073] In one embodiment, the reflective component 5 further includes a reflector;

[0074] Multiple reflectors are provided and are installed around the periphery of the housing 1.

[0075] In this embodiment, for the display, there are four reflectors, which are distributed around the periphery of the housing 1 to correspond to the periphery of the display substrate 2.

[0076] like Figure 6 As shown, in one possible embodiment, the spotlight assembly 4 is provided as a plurality of units, distributed on the inner surface of the housing 1;

[0077] Correspondingly, the display substrate 2 is divided into several sub-regions, and each spotlight assembly 4 corresponds to a sub-region of the display substrate 2.

[0078] In this embodiment, there are 3 to 6 spotlight assemblies 4, which can be evenly installed on the inner surface of the housing 1 in a vertical or horizontal distribution to correspond to each sub-area on the display substrate 2. By setting multiple spotlight assemblies 4, each spotlight assembly 4 is responsible for its corresponding sub-area, reducing the workload of each spotlight assembly 4.

[0079] In one embodiment, the optimal distance between the spotlight assembly 4 and the display substrate 2 is 20 to 70 mm.

[0080] In this embodiment, there is a distance between the spotlight assembly 4 and the display substrate 2, with the optimal distance being 20-70mm. Experiments have shown that if the number of spotlight assemblies 4 is less than 20mm, due to the close distance and limited illumination range of the spotlight assemblies 4, a large number of spotlight assemblies 4 are required, which is uneconomical and cumbersome to install. If the number of spotlight assemblies 4 is greater than 70mm, due to the greater distance, the intensity of the beam reaching the pixels weakens, affecting the actual visual experience.

[0081] like Figure 3 As shown, in one embodiment, a plurality of pixel substrates 3 are provided with non-transparent baffles 6 between each other.

[0082] In this embodiment, the non-transparent baffle 6 is specifically disposed between every two pixel substrates 3, which can reduce interference to other pixel positions when the light beam reaches the designated position.

[0083] Preferably, the pixel controller 31 can also act as a non-transparent baffle 6 disposed between every two pixel substrates 3, which can save costs.

[0084] The present invention has been described through the above embodiments. However, it should be understood that the above embodiments are for illustrative purposes only and are not intended to limit the invention to the scope of the described embodiments. Furthermore, those skilled in the art will understand that the present invention is not limited to the above embodiments, and many more variations and modifications can be made based on the teachings of the present invention, all of which fall within the scope of protection claimed by the present invention.
