Description

Technical Field

[0001] The present invention belongs to the technical field of backlight glass, and in particular relates to a multi-partitioned mini light source glass device. Background Art

[0002] In the display field, Local Dimming means local backlight adjustment. The light source LED beads in the backlight module can be adjusted in different areas according to the brightness of the image, increasing the brightness of the highlighted part of the image and reducing the brightness of the dark area of ​​the image. Compared with the conventional Global Dimming (overall brightness adjustment), Local Dimming can make the display image have a higher contrast. At the same time, the reduction in the brightness of the dark area also reduces the backlight power accordingly.

[0003] In the prior art, Edge Local Dimming for test-type backlight modules has fewer partitions and limited contrast improvement. Full Array Local Dimming for direct-type backlight modules has a better effect. When there are enough partitions, the contrast is significantly improved. At the same time, the backlight power can be greatly reduced to achieve the purpose of energy saving. However, the design cost of realizing multiple partitions is relatively high, and the direct-type backlight module is thick and cannot withstand high temperatures. Summary of the invention

[0004] The purpose of the present invention is to provide a multi-partitioned mini light source glass device to solve the technical problems of high design cost of multi-partitions and thick thickness of direct-type backlight modules, so as to achieve the purpose of having a thin backlight module with good effect and high temperature resistance.

[0005] In order to solve the above technical problems, the present invention provides a multi-partitioned mini light source glass device, including:

[0006] A top glass substrate, a silver-plated cathode layer, a first hole electron transport layer, a first hole electron blocking layer, an organic light-emitting material layer, a second hole electron transport layer, a second hole electron blocking layer, a coating layer, an ITO cathode layer and a bottom glass substrate;

[0007] A plurality of polygonal light-emitting material bodies are arranged in the organic light-emitting material layer.

[0008] Furthermore, the overall thickness of the first hole electron transport layer, the first hole electron blocking layer, the organic light-emitting material layer, the second hole electron transport layer, and the second hole electron blocking layer is 5-10 nanometers.

[0009] Furthermore, the thickness of the coating layer is 100 nanometers.

[0010] Furthermore, the ITO positive electrode layer has a resistance of 8-12 ohms / square, a light transmittance greater than 88%, and a thickness of 1200-1300 angstroms.

[0011] Furthermore, the three chromaticities of the organic light-emitting material layer are R30%, G30% and B10%.

[0012] Furthermore, the thickness of the top glass substrate and the bottom glass substrate is 0.1-0.7 mm.

[0013] Furthermore, the polygonal luminescent material body has a shape of one or more of a triangle, a regular polygon or an irregular shape.

[0014] The beneficial effects of the present invention are:

[0015] 1. The top glass base layer, the silver-plated cathode layer, the first hole electron transport layer, the first hole electron blocking layer, the organic light-emitting material layer, the second hole electron transport layer, the second hole electron blocking layer, the coating layer, the ITO cathode layer and the bottom glass substrate have an overall thickness of 0.2-1.4 mm, which can greatly reduce the backlight power and achieve the purpose of energy saving. In addition, the overall thickness is thin and the heat dissipation effect is good. In addition, because the overall structure is made of high temperature resistant materials, the overall high temperature resistance effect is good.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example:

[0023] like Figure 1 As shown, a multi-partitioned mini light source glass device includes: a top glass base layer 1, a silver-plated cathode layer 2, a first hole electron transport layer 3, a first hole electron blocking layer 4, an organic light-emitting material layer 5, a second hole electron transport layer 6, a second hole electron blocking layer 7, a coating layer 8, an ITO cathode layer 9 and a bottom glass substrate 10, which are sequentially evaporated and bonded from top to bottom. Among them, a plurality of polygonal light-emitting material bodies 51 are arranged in the organic light-emitting material layer 5. The shape of the polygonal light-emitting material body 51 is one or more of a triangle, a regular polygon or an irregular shape. In the present embodiment, the polygonal light-emitting material body 51 is a triangle, which is convenient for scattering the incident light. The three chromaticities of the organic light-emitting material layer 5 are R30%, G30% and B10%.

[0024] The overall thickness of the first hole electron transport layer 3, the first hole electron blocking layer 4, the organic light emitting material layer 5, the second hole electron transport layer 6 and the second hole electron blocking layer 7 is 5-10 nanometers.

[0025] In this embodiment, the thickness of the coating layer 8 is 100 nanometers. The ITO positive electrode layer 9 has a resistance of 8-12 ohms / square, a transmittance greater than 88%, and a thickness of 1200-1300 angstroms. The high transmittance and extremely thin thickness of the ITO positive electrode layer 9 not only have the original effect, but also improve the transmittance through the extremely thin thickness, and reduce the overall thickness, and finally save costs and reduce weight.

[0026] The thickness of the top glass substrate and the bottom glass substrate 10 is 0.1-0.7 mm.

[0027] In summary: through the ultra-thin setting of 0.2-1.4 mm overall thickness of the top glass base layer 1, the silver-plated negative electrode layer 2, the first hole electron transport layer 3, the first hole electron blocking layer 4, the organic light-emitting material layer 5, the second hole electron transport layer 6, the second hole electron blocking layer 7, the coating layer 8, the ITO positive electrode layer 9 and the bottom glass substrate 10, the backlight power can be greatly reduced to achieve the purpose of energy saving. In addition, the overall thickness is thin and the heat dissipation effect is good. In addition, because the overall structure is made of high temperature resistant materials, the overall high temperature resistance effect is good.
