Description

Technical Field

[0001] This utility model relates to the field of transparent displays, and in particular to a transparent display structure using a quantum dot composite film. Background Technology

[0002] With the rapid development of commercial displays, smart retail and other fields, transparent display devices have become a key technology for improving display effects because they can simultaneously realize the dual functions of information display and object transparency. For example, in commercial shop windows, vending machines and product display cabinets, transparent displays can combine product information with the actual objects to enhance the user's visual experience and interactivity.

[0003] Currently, most transparent display technologies are based on improvements to the traditional liquid crystal display (LCD) structure. However, they have many limitations in practical applications. The main reason is that existing transparent display devices are limited by heat dissipation and temperature resistance, and can usually only be used indoors. If placed outdoors, the direct sunlight and the heat generated by the internal LED light source and control board will cause the device temperature to rise sharply. This not only accelerates the aging of core components such as quantum dot materials and liquid crystal modules, shortening their lifespan, but also makes it impossible to use quantum dot technology to improve the color of the display, thus necessitating improvement. Utility Model Content

[0004] The purpose of this invention is to provide a transparent display structure using a quantum dot composite film, which has the advantages of ensuring display quality and extending the service life of the device.

[0008] The present invention is further configured such that the quantum dot brightening composite film is composed of a polarizer, a reflective brightening film and a quantum dot film arranged sequentially from the outside to the inside.

[0009] The present invention is further configured such that: an inclined fitting part for installing LED light strips is fixedly connected to the top of the end of the internal cavity away from the LCD display screen, and the angle between the fitting surface of the inclined fitting part and the horizontal plane is not less than 15°.

[0010] The present invention is further configured such that the LED light source in the LED light strip is a blue LED or a KSF LED with a color temperature of not less than 5000K.

[0011] The present invention is further configured such that: the circulating heat dissipation duct structure includes a circulating heat dissipation duct disposed between the display holder and the internal cavity; the internal cavity has an air-cooled internal circulation inlet and an air-cooled internal circulation outlet connected to the circulating heat dissipation duct on both sides; and an intake fan and an exhaust fan are fixedly connected to the bottom of the display holder near the air-cooled internal circulation inlet and the air-cooled internal circulation outlet.

[0012] The present invention is further configured such that: the end of the display holder away from the LCD screen is provided with a back plate, the back plate is provided with an embedded handle, and the back plate and the display holder are magnetically connected based on magnets.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] Example: refer to Figures 1 to 4 A transparent display structure using a quantum dot composite film includes a display holder 1 and an internal cavity 2 fixedly connected within the display holder 1. A reflective heat-insulating layer composed of a mixture of hydrophobic TiO2 gel powder and matte paint is sprayed onto the surface of the internal cavity 2. An LCD display screen 3 is fixedly connected to the front of the display holder 1. A heat-insulating film 4 is attached to the front of the LCD display screen 3, and an anti-reflective layer composed of nano-silica aerogel is provided on the surface of the heat-insulating film 4. A quantum dot brightness-enhancing composite film 5 is attached to the back of the LCD display screen 3. The quantum dot brightness-enhancing composite film 5 is composed of a polarizer, a reflective brightness-enhancing film, and a quantum dot film arranged sequentially from the outside to the inside. The anti-reflective layer formed by nano-silica aerogel on the surface of the heat-insulating film 4 enhances the heat insulation... The thermal effect is enhanced by a reflective heat insulation layer made of hydrophobic TiO2 aerogel powder mixed with matte paint sprayed on the internal cavity 2, which improves light reflection and heat insulation. This effectively reflects LED light energy to the display area, further optimizing the display effect and keeping the picture clear and vibrant even in a transparent state. A circulating heat dissipation air duct structure 6 is provided between the display holder 1 and the internal cavity 2 for heat dissipation, so that the display can effectively dissipate heat in outdoor environments and ensure the display effect. The use of hydrophobic TiO2 is also because the internal cavity 2 can be used to display products. However, in order to prevent dirt from getting on the internal surface of the cavity, hydrophobic aerogel TiO2 powder is added to the reflective heat insulation layer material to prevent dirt from getting on the inside.

[0018] refer to Figures 2 to 3Specifically, the top of the internal cavity 2, away from the LCD display screen 3, is fixedly connected to an inclined bonding part 7 for mounting the LED light strip 8. The angle between the bonding surface of the inclined bonding part 7 and the horizontal plane is not less than 15°. By placing the LED light source on the inclined bonding part 7 with an angle of not less than 15°, the LED light source can be effectively utilized, further optimizing the display effect and keeping the picture clear and bright even in a transparent state. The LED light source in the LED light strip 8 uses blue LEDs or KSF LEDs with a color temperature of not less than 5000K. By setting a quantum dot brightness enhancement composite film 5, which is composed of a polarizer, a reflective brightness enhancement film, and a quantum dot film, and working with the blue LED or KSF LED light source with a color temperature of not less than 5000K, the quantum dots can be excited to produce purer red and green light, greatly improving the display brightness and color saturation.

[0019] refer to Figure 4 Specifically, the circulating heat dissipation duct structure 6 includes a circulating heat dissipation duct 61 disposed between the monitor holder 1 and the internal cavity 2. The internal cavity 2 has air-cooled internal circulation inlet 62 and air-cooled internal circulation outlet 63 connected to the circulating heat dissipation duct 61 on both sides. An intake fan 64 and an exhaust fan 65 are fixedly connected at the bottom of the monitor holder 1 near the air-cooled internal circulation inlet 62 and the air-cooled internal circulation outlet 63. External air is drawn in by the intake fan 64 and enters the circulating heat dissipation duct 61 through the air-cooled internal circulation inlet 62. The air is transported around the internal cavity 2 along the circulating heat dissipation duct 61 for cooling. Finally, the air is discharged into the external air by the exhaust fan 65 after passing through the air-cooled internal circulation outlet.

[0020] refer to Figure 1 Specifically, a back plate 66 is detachably provided at the end of the display holder 1 away from the LCD screen 3. An embedded handle 67 is provided on the back plate 66. The back plate 66 and the display holder 1 are magnetically connected by a magnet 68, so that the back plate 66 can be quickly disassembled for maintenance.

[0021] Brief description of the operating principle: By setting up a quantum dot brightness enhancement composite film 5, which is composed of a polarizer, a reflective brightness enhancement film, and a quantum dot film, and using a blue LED or a KSF LED light source with a color temperature of not less than 5000K, the quantum dots can be excited to produce purer red and green light, significantly improving display brightness and color saturation. The LED light source is placed on the inclined bonding part 7 with an inclination angle of not less than 15°, so that the LED light source can be effectively utilized. At the same time, by setting nano-silica aerogel on the surface of the heat insulation film 4 to form an anti-reflective layer, the heat insulation effect is improved. Combined with the reflective heat insulation layer made of hydrophobic TiO2 aerogel powder and matte paint sprayed on the internal cavity 2, the light reflection and heat insulation effects are enhanced, so that the LED light energy can be effectively reflected to the display area, further optimizing the display effect and keeping the picture clear and bright even in a transparent state.
