Abstract

The utility model discloses a COB MINILED blue light lamp plate is shaded, through set up the pad that flip chip corresponds the size on the base plate, blue light chip fixes on the corresponding position of base plate set up the silica gel layer on the base plate, cover the base plate reaches blue light chip need not traditional LED encapsulation, saves materials such as LED support, gold thread, and direct solid brilliant reduction production processes on PCB.

Description

Backlight COB MINILED blue light lamp panel

Technical Field

The utility model relates to a liquid crystal display technology field, more specifically the utility model relates to a COB MINILED blue light lamp plate is shaded from sun which says so.

Background

At present, with the continuous development of science and technology, the requirements of consumers on the liquid crystal display industry are higher and higher, and the miniLED backlight becomes a new development trend of the liquid crystal display industry. However, since the miniLED backlight adopts the partition dimming technology, the more densely the LEDs are arranged, the more accurate the arrangement can be made with the smaller display, and the higher brightness, the higher contrast and the more precise visual experience can be brought to the picture

However, most miniLED lamp panel light sources on the market at present are composed of packaged blue LEDs such as 3030 (3.0 mm x 3.0 mm)/3528 (3.5 mm x 2.8 mm) and the like with LED supports attached to PCBs, and the LED spacing cannot reach the small spacing density of COB chips due to the self-packaging size and the limitation of the production process

Therefore, how to save materials such as an LED bracket and a gold wire, and directly fix the die on the PCB reduces the production processes, and increasing the arrangement density of the LED lamp panel is a problem that needs to be solved urgently by those skilled in the art.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a COB MINILED blue light lamp plate is shaded, through set up the pad that flip chip corresponds the size on the base plate, blue light chip fixes on the corresponding position of base plate set up the silica gel layer on the base plate, cover the base plate reaches blue light chip need not traditional LED encapsulation, saves materials such as LED support, gold thread, and direct solid brilliant reduces production processes on PCB.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a backlight COB MINILED blue light lamp panel, = includes: a substrate and a blue light chip; the substrate is provided with a bonding pad with the size corresponding to that of the flip chip, the blue light chip is fixed on the corresponding position of the substrate, and the substrate is provided with a silica gel layer to cover the substrate and the blue light chip.

Preferably, the distance between the blue light chips is at least 1mm.

Preferably, the substrate edge is provided with a substrate process edge.

According to the technical scheme, compare with prior art, the utility model provides a COB MINILED blue light lamp plate is shaded, through set up the pad that flip chip corresponds the size on the base plate, the blue light chip is fixed on the corresponding position of base plate set up the silica gel layer on the base plate, cover the base plate reaches the blue light chip need not traditional LED encapsulation, saves materials such as LED support, gold thread, and direct solid brilliant reduction production processes on PCB.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the provided drawings without creative efforts.

Fig. 1 is a schematic structural diagram provided by the present invention.

Fig. 2 is a schematic sectional view of the present invention.

Wherein, 1 is the base plate, 2 is the blue light chip, 3 is the silica gel layer, and 4 is base plate technology limit.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The embodiment of the utility model discloses COB MINILED blue light lamp plate is shaded from sun, include: a substrate 1 and a blue light chip 2; set up the pad that the face down chip corresponds the size on the base plate, blue light chip 2 is fixed on the corresponding position of base plate 1, sets up silica gel layer 3 on base plate 1, covers base plate 1 and blue light chip 2.

In order to further optimize the technical scheme, the minimum distance between the blue light chips 2 is 1mm.

In order to further optimize the technical scheme, a substrate process edge 4 is arranged at the edge of the substrate 1.

The traditional LED packaging is not needed, the materials such as an LED bracket and a gold wire are saved, the production procedures are reduced by directly fixing the crystal on the PCB

Because blue light chip self volume is less (generally 6 x 12mil/8 x 12mil), can increase LED lamp plate density of arranging greatly, improve miniLED TV luminance, to comparison, more meticulous detail show, improve miniLED TV's vision enjoyment.

The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other. The device disclosed by the embodiment corresponds to the method disclosed by the embodiment, so that the description is simple, and the relevant points can be referred to the method part for description.
