Embodiment Construction

[0055] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0056] see figure 1 The first embodiment of the present invention provides a light source assembly 10, wherein the light source assembly 10 includes a carrier 11 and a plurality of LED chips 12 uniformly arranged on the carrier 11, the light source assembly 10 further includes a light uniform layer 11, The same uniform light layer 13 is arranged on the plurality of LED chips 12 . The light emitted by the LED chip 12 directly enters into the homogeneous layer 13 for scattering, forming a continuous and uniform light emitting surface. The area of ​​the light-emitting surface is equ...

Abstract

The invention provides a light source assembly and a display device thereof. The light source assembly includes a carrier, a plurality of LED chips and a fluorescent layer covering the carrier and theLED chips; a plurality of pad patterns and a plurality of wires are arranged on the surface, provided with the LED chips, of the carrier, positive and negative electrodes of each LED chip are weldedto the two corresponding adjacent pad patterns respectively, and the wires are connected with partial or all pad patterns; the area of the orthographic projection of each LED chip is greater than or equal to the area of a region occupied by the two pad patterns corresponding to the LED chip. Compared with traditional backlight sources, the light source assembly and the display device thereof havethe advantages that more LED chips can be arranged on the carrier with the same area to meet requirements for various light-emitting effects and the uniformity. Compared with traditional side light-emitting light source assemblies or direct downward light-emitting assemblies, the distribution density of the light source assembly can be lower, and the situation cannot occur that dark regions are caused by excessive spacing of LED chips.

Description

【Technical field】 [0001] The invention relates to the field of LED display, in particular to a light source component, a display device and the preparation of the light source component. 【Background technique】 [0002] LED (Light Emitting Diode) is an existing common solid-state light source, which has the characteristics of long life, high stability, energy saving and environmental protection. Existing LED display components generally package a plurality of LED chips on a circuit board. No matter it adopts side-type lighting or direct-light lighting, the existing LED light source has a surrounding frame or a closed structure so that all The above-mentioned fluorescent glue is formed on the LED chip by coating, but such a preparation process often needs to set a light reflection area at the edge of the LED light source, so that the LED light source has an uneven luminous effect and needs to set a structure such as a reflective plate to To achieve the effect of uniform light...
