Description

Technical Field

[0001] This utility model relates to the field of display technology, specifically an energy-saving intelligent 100-inch large-screen display device. Background Technology

[0002] In recent years, display technology has advanced by leaps and bounds, with large-screen display technologies, such as large-screen TVs and projectors, primarily used in the home, experiencing rapid development. In particular, the integration of smart technology has enabled TVs and projectors to install applications, achieving interactive large-screen experiences and providing an excellent platform for home audio-visual entertainment.

[0003] However, the power consumption of smart TVs and smart projectors is astonishing. Taking smart TVs as an example, if they reach 75 inches or even 100 inches, the TV display module requires a lot of power to drive sufficient display brightness. In addition, due to the addition of smart technology, the CPU power consumption will also increase. Brightness is a very critical indicator for projectors, and they need to be able to display normally in daylight or in bright environments. Therefore, higher projection brightness must be used to overcome this difficulty, and thus their power consumption will remain high for a long time.

[0004] Based on the above reasons, this utility model provides an energy-saving intelligent 100-inch large-screen display device. While the driving power consumption required for the small screen is low, it uses the concave mirror magnification principle to enlarge the image of the small screen without affecting its clarity. At the same time, it takes into account the requirements of environmental shading and intelligent compatibility, and achieves the effect of large-screen projection with low power consumption. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an energy-saving intelligent 100-inch large-screen display device. Based on the low driving power required for small screens, it utilizes the concave mirror magnification principle to enlarge the image of the small screen without affecting its clarity. At the same time, it takes into account the requirements of environmental shading and intelligent compatibility, and achieves the effect of large-screen projection with low power consumption.

[0006] To achieve the above objectives, this utility model provides an energy-saving intelligent 100-inch large screen display device, including a device body, an upper cover plate on the top of the device body, upper side plates connected to both sides of the upper cover plate by screws, the upper side plates are slidably connected to the lower side plates by a sliding groove 1 set on the upper side plate, the lower side plates rotate along the axis by a rotating shaft 1 set at a sliding groove 2 on the side of the device body, and the upper cover plate rotates along the axis by a rotating shaft 2.

[0007] The device body has a straight glass panel that is tilted inward. The inside of the straight glass panel is covered with a semi-transparent and semi-reflective film. Inside the straight glass panel and below its top, there is a concave glass panel. The outside of the concave glass panel is covered with a silver coating. A light source is located below the straight glass panel.

[0008] The slide is located at the outer edge of the upper side plate and has the same curvature as the outer edge of the upper side plate.

[0009] The outer edges of the upper and lower side panels are on the same arc.

[0010] The concave glass has a concave shape on the inside of the equipment body and a convex shape on the outside.

[0011] The center point of the concave glass and the refraction point of the light source in the semi-transparent and semi-reflective film are on the same horizontal line.

[0012] The light source is the 5.5-inch display screen of the playback terminal.

[0013] The device body includes a control circuit, which includes a main board, a screen board, and a sub-board. The screen board is electrically connected to the CPU on the main board through a power management unit (PMU). The CPU is electrically connected to the projection chip on the screen board.

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] See Figures 1-4 This utility model provides an energy-saving intelligent 100-inch large screen display device, including a device body. The top of the device body is provided with an upper cover plate 16. The two sides of the upper cover plate 16 are respectively connected to upper side plates 8 by screws 11. The upper side plates 8 are slidably connected to the slide rails 10 on the lower side plates 9 by a slide groove 12 provided on the upper side plate. The lower side plates 9 are rotated along the axis by a rotating shaft 14 located at a slide groove 13 on the side of the device body. The upper cover plate 16 is rotated along the axis by a rotating shaft 15.

[0023] A straight glass 2 is inclined inward on the main body of the device. A semi-transparent and semi-reflective film 1 is provided on the inner side of the straight glass 2. A concave glass 4 is provided inside the straight glass 2 and below its top. A silver coating 3 is provided on the outer side of the concave glass 4. A light source 5 is provided below the straight glass 2.

[0024] The slide groove 12 is located at the outer edge of the upper side plate 8 and has the same curvature as the outer edge of the upper side plate 8.

[0025] The outer edges of the upper side plate 8 and the lower side plate 9 are on the same arc.

[0026] The concave glass 4 has a concave shape on the inside of the equipment body and a convex shape on the outside.

[0027] The center point of the concave glass 4 and the refraction point of the light source 5 on the semi-transparent and semi-reflective film 1 are on the same horizontal line.

[0028] Light source 5 is the 5.5-inch display screen of the playback terminal.

[0029] The device body includes a control circuit, which includes a main board, a screen board, and a sub-board. The screen board is electrically connected to the CPU on the main board through a power management unit (PMU). The CPU is electrically connected to the projection chip on the screen board. The CPU is electrically connected to the power amplifier (PA) on the sub-board. The CPU is electrically connected to the USB interface on the sub-board. The CPU is connected to the power, volume, and brightness switches on the sub-board. The CPU is electrically connected to the memory module, communication module, and external memory card.

[0030] Working principle:

[0031] See Figures 1-4 This invention requires minimal adjustment. When light 6 is emitted from the 5.5-inch screen of the light source 5 onto the surface of the semi-transparent and semi-reflective film 1, 50% of the light is refracted onto the concave mirror composed of the concave glass 4 and the silver coating 3. When this portion of the light reaches the surface of the silver coating 3, it is 100% reflected by the concave mirror 1 and shines onto the inclined straight glass 2 composed of the straight glass 2 and the semi-transparent and semi-reflective film 1. When the light reaches the semi-transparent and semi-reflective film 1, 50% of the light is transmitted out and enters the human eye observation position 7 to be observed by the human eye.

[0032] Since the mirror composed of concave glass 4 and silver coating 3 is a concave mirror, and concave mirrors have the same optical properties as convex lenses, they can magnify images. Therefore, the image displayed on the 5.5-inch screen of the light source 5 will be magnified on the flat glass 2 and enter the human eye.

[0033] The principle behind the light brightness is as follows: Assuming the normal brightness of the 5.5-inch screen of light source 5 is 1000 nits (the brightness of a normal mobile phone screen), when the light first reaches the semi-transparent and semi-reflective film 1, it is attenuated by 50%, becoming 500 nits. When it reaches the concave mirror of the concave glass 4 and the silver coating 3, since it is a total internal reflection mirror, the reflected light is still 500 nits. When it passes through the semi-transparent and semi-reflective film 1 for the second time, it is attenuated by another 50%, so the brightness reaching the eye is 250 nits. A normal, comfortable light brightness is between 200 and 300 nits; this is the right brightness for the human eye. Otherwise, too bright or too dim a light will cause discomfort to the eyes.

[0034] The structural and working principle of this display device is as follows:

[0035] The upper cover plate 16 can rotate along the axis via the second pivot 15. The upper side plate 8 is fixed to the upper cover plate 16 by screws 11, and the lower side plate 9 can rotate along the axis via the first pivot 14. At the same time, the slide rail 10 on the lower side plate 9 slides along the first slide groove 12. When the upper cover plate 16 is lowered, it first drives the upper side plate 8 to slide down until it is aligned with the lower side plate 9 and then slides into the second slide groove 13 together.

[0036] The above structural design, with the top cover 16, left and right upper side panels 8, and left and right lower side panels 9 working together to achieve the light-blocking effect, allows for fine-tuning of the light-blocking effect by adjusting the position of the top cover 16. When using the above structure, the influence of ambient light on the viewer within the light-blocking area is minimal.

[0037] I. Based on the hardware architecture of the above embodiments of this utility model, calculate the overall power consumption:

[0038] 1. Display module: Driven by the screen panel, the 5.5-inch screen reaches a brightness of 1000 nits, with 250 nits reaching the eyes. The overall power consumption of the display module is 7W.

[0039] 2. Sound section: Since we used a 3W speaker module to achieve a relatively good sound effect, the power consumption of the sound section is 3W.

[0040] 3. Motherboard CPU section: The quad-core CPU runs Android 12 at full load, including the maximum power consumption of Wi-Fi and Bluetooth. The maximum power consumption of this part is 10W.

[0041] Based on a total power consumption of 20W, calculate the daily power consumption:

[0042] Power consumption per hour: 20W ÷ 1000 = 0.02 kWh.

[0043] 24-hour power consumption: 0.02 × 24 = 0.48 kWh.

[0044] II. If we use a 100-inch TV or projector to calculate the daily power consumption, the data would be:

[0045] 1. The power consumption of a 100-inch TV varies significantly depending on the technology type (LED, OLED, laser TV, etc.) and brand:

[0046] Mainstream LED / LCD TVs: 150W~350W;

[0047] High-end laser TVs: 200W~350W (such as Sony, Sharp and other brands);

[0048] Some new models: such as the Thunderbird 100MAX 25, have a total power of 600W, while the Coocaa Max100 has 480W (high brightness and local dimming technology result in higher power consumption).

[0049] Overall average: approximately 200W~300W (most common models).

[0050] The daily power consumption of a television is as follows:

[0051] 24-hour power consumption calculation, taking an average power of 250W as an example:

[0052] Power consumption per hour: 250W ÷ 1000 = 0.25 kWh;

[0053] 24-hour power consumption: 0.25 × 24 = 6 kWh.

[0054] 2. The power consumption of a projector mainly depends on its type and functional configuration:

[0055] Home projectors: 50W~300W (LED light source models are usually 50W~150W, traditional lamp models are 150W~300W);

[0056] Business / Education Projectors: 200W~400W (high brightness, high resolution models may be even higher);

[0057] Engineering projectors: 1000W~5000W (for large venues, with significantly increased power consumption);

[0058] Based on common models, the average power consumption of home and general business projectors is approximately 150W to 250W.

[0059] The daily power consumption is as follows:

[0060] Taking an average power consumption of 200W as an example:

[0061] Power consumption per hour: 200W ÷ 1000 = 0.2 kWh;

[0062] 24-hour power consumption: 0.2 × 24 = 4.8 kWh.

[0063] Third, compared with the 6 kWh / day of a TV and the 4.8 kWh / day of a projector, the power consumption of this utility model is only 0.48 kWh, which is more than 10 times less. Under the premise of this power consumption, a 151-inch large screen display can be achieved, and a brightness of 250 nits can be achieved, and it is not affected by external light.

[0064] The above are merely preferred embodiments of this utility model, intended only to aid in understanding the method and core concept of this application. The scope of protection of this utility model is not limited to the above embodiments; all technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the scope of protection of this utility model.

[0065] This invention comprehensively solves the problem of excessive power consumption caused by the use of large-inch televisions or projectors for large-screen displays in existing technologies. By using the magnification principle of concave mirrors and optical design to magnify and project the light source, it eliminates the excessive energy consumption required by physical screens and the high energy consumption caused by environmental influences and high brightness requirements. It can reduce the high energy consumption of traditional televisions or projectors to about one-tenth, while still maintaining clear and stable projected images, providing a significant technical guarantee for energy saving and economy in the display field.
