Description
Technical Field
The utility model relates to a LED technical field, concretely relates to novel COB display panel.
Background
In recent years, the market of LED (Light-Emitting Diode) display screens has created transparent display screens and grid display screens, and LED transparent display screens are popular with users due to their characteristics of transparency, lightness, novelty, etc., and have rapidly developed, and have rapidly entered into indoor or semi-outdoor application fields such as show windows, leases, architectural signs, etc.; the LED grille display screen is popular in the field of outdoor LED display screens due to the characteristics of permeability, heat dissipation, installation cost saving, simplicity and convenience in installation and the like. These emerging applications provide a new visual aesthetic enjoyment for the user, develop rapidly, and open up new application areas for LED display applications.
Traditional COB display panel's luminance is not enough, and the consumption is than higher moreover, and the contrast is also poor and strong people's intention, to sum up, the utility model discloses a novel COB display panel.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a novel COB display panel, structural design is reasonable, and luminance is high, and the contrast is high, excellent in use effect, the practicality is strong.
In order to achieve the above purpose, the present invention is realized by the following technical solution: the utility model provides a novel COB display panel, includes circuit board, driver IC, encapsulation glue film and pixel unit, the circuit board bottom is provided with driver IC, and the circuit board openly is provided with the pixel unit, and the pixel unit outside is through the encapsulation glue film encapsulation, the encapsulation glue film adopt two-layer to glue, be the high transparent optical material layer of rolling over and roll over black optical material layer with low respectively, low roll over black optical material layer setting and roll over transparent optical material layer outside at the high.
Preferably, the pixel units are respectively provided with red, green and blue three-primary-color LED light-emitting chips.
Preferably, the thickness of the high-refractive-index transparent optical material layer is 0.35-0.5 mm.
Preferably, the thickness of the low refractive black optical material layer is 0.05-0.1 mm.
The utility model has the advantages that:
1. the brightness of the COB display panel can be improved by 10-20%;
2. the power consumption of a panel with the same contrast and brightness can be reduced by 20%;
3. the utility model discloses a COB display panel contrast ratio ordinary panel contrast improves 10%.
Drawings
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments;
fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
Referring to fig. 1, the following technical solutions are adopted in the present embodiment: the utility model provides a novel COB display panel, includes circuit board 1, driver IC2, packaging adhesive layer 3 and pixel unit 4, and 1 bottom of circuit board is provided with driver IC2, and circuit board 1 openly is provided with pixel unit 4, and pixel unit 4 is outside through the packaging of packaging adhesive layer 3, packaging adhesive layer 3 adopt two-layer to seal the glue, be the high transparent optical material layer 31 of rolling over and roll over black optical material layer 32 with low respectively, low black optical material layer 32 setting of rolling over in the high transparent optical material layer 31 outside of rolling over.
It should be noted that the pixel units 4 are respectively provided with red, green and blue LED light emitting chips 41.
It is worth noting that the surface of the circuit board 1 is further provided with a layer of black PP5, so that the consistency of ink color is improved.
It is noted that the thickness of the high refractive index transparent optical material layer 31 is 0.35-0.5 mm.
In addition, the thickness of the low refractive black optical material layer 32 is 0.05-0.1 mm.
The adhesive layer of the embodiment adopts multiple times of adhesive sealing, the first layer is made of high-refractive-index transparent optical material, the thickness of the adhesive is 0.35-0.5mm, and the second layer is made of low-refractive-index black optical material, and the thickness of the second layer is 0.05-0.1 mm. The COB panel brightness of the packaging structure can be improved by 10% -20%, the panel power consumption with the same brightness of the contrast can be reduced by 20%, the contrast is 10% higher than the common one, the structure of the COB display panel of the specific embodiment is different from the common panel structure, the packaging layer adopts a double-layer structure, the packaging layer of the common panel is only one layer, and the using effect of the packaging structure is not as good as that of the panel.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
