Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of backlight modules, and in particular relates to an integrated structure of a glass-based back plate and a light plate. Background Art
[0002] In direct-type miniled backlight modules, aluminum is often used as the conductive circuit board of the backlight module, and metal or plastic is used as the back panel of the backlight module. A reflective sheet is used on the inner side of the conductive circuit board to reflect the LED light. The reflective sheet needs to reserve specific hollow positions to install LED lamp beads. For miniled backlight modules, due to the large number of lamp beads, the number of hollow positions of the reflective sheet increases accordingly. Since the lamp beads have a certain tolerance during the welding process, the hollow area on the reflective sheet will be larger than the size of the lamp beads. This causes the reflective sheet to be unable to completely cover the non-lamp bead welding area on the inside of the back panel, which in turn causes light leakage at the exposed position, affecting the optical brightness of the backlight module. Utility Model Content
[0003] The purpose of the utility model is to provide an integrated structure of a glass-based back panel and a lamp panel to solve the technical problem that the reflective sheet cannot completely cover the non-lamp bead welding area on the inner side of the back panel, thereby causing light leakage at the exposed position and affecting the optical brightness of the backlight module. The utility model utilizes the high light transmittance of the glass and sets the reflective layer on the side opposite to the LED lamp beads, thereby avoiding light leakage caused by hollowing out the reflective layer.
[0004] In order to solve the above technical problems, the utility model provides a glass-based back panel and a light panel integrated structure, comprising:
[0005] A glass substrate and a reflective layer disposed on the inner side of the glass substrate, wherein a decorative film layer is disposed on a side of the reflective layer away from the glass substrate;
[0006] A conductive circuit layer and a protective layer are sequentially arranged outside the reflective layer, and a plurality of mini-LED lamp beads are arranged on the conductive circuit layer and penetrate through the protective layer;
[0007] The four sides of the glass substrate are provided with reflective UV adhesive layers.
[0008] Furthermore, the decorative film is a black brushed metal decorative film.
[0009] Furthermore, the cross section of the reflective UV adhesive layer is arc-shaped and covers both sides of the glass substrate.
[0010] Furthermore, the glass substrate is made of float glass with a thickness of 0.7-5 mm.
[0011] The beneficial effects of the utility model are:
[0012] 1. By using glass instead of metal aluminum as the conductive circuit board of the miniled backlight module, since glass is a highly transparent material, setting the reflective layer on the outer surface of the glass can achieve the same reflective effect, and there is no need to reserve a hollow position for lamp bead welding, which increases the optical brightness of the backlight module;
[0013] 2. A black brushed metal decorative film is directly attached to the outside of the reflective layer to protect the reflective coating, increase the aesthetics, and absorb a small amount of light leaking from the reflective layer, thereby achieving the effect of combining the conductive circuit board and the back panel into one.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Example:
[0026] like Figure 1 As shown, a glass-based back panel and light panel integrated structure includes: a glass substrate 1 and a reflective layer 2 arranged on the inner side of the glass substrate 1, and a decorative film layer 3 is arranged on the side of the reflective layer 2 away from the glass substrate 1, wherein the glass substrate 1 is made of float glass with a thickness of 0.7-5 mm. The decorative film is a black metal brushed decorative film.
[0027] Among them, a conductive circuit layer 4 and a protective layer 41 are sequentially arranged on the outer side of the reflective layer 2, and a plurality of mini-LED lamp beads 5 are arranged on the conductive circuit layer and penetrate through the protective layer 41; and reflective UV adhesive layers 6 are arranged on the four sides of the glass substrate 1.
[0028] According to the strength requirement of the backlight module for the back panel, the glass can be chemically or physically strengthened, or the original material can be used directly; the glass transmittance is above 88%, and the reflectivity of the reflective layer 2 on the outer side of the glass back panel is above 94%.
[0029] In this embodiment, the cross section of the reflective UV adhesive layer 6 is arc-shaped and covers the four sides of the glass substrate 1. The four end faces of the glass substrate 1 are coated with reflective UV adhesive by dispensing technology, with a reflectivity of more than 90% to prevent light leakage from the end faces.
[0030] A black metal brushed decorative film is attached to the outside of the reflective layer 2. The decorative film protects the reflective layer 2 and increases the aesthetics. It can also absorb a small amount of light transmitted by the reflective sheet. A conductive circuit layer and a protective layer 41 are printed on the inside of the glass back plate, and then the LED lamp beads are welded.
[0031] To sum up: by using glass material instead of metal aluminum as the conductive circuit board of the miniled backlight module, since glass is a highly transparent material, the reflective layer 2 is set on the outer surface of the glass, which can achieve the same reflective effect, and there is no need to reserve a hollow position for welding lamp beads, thereby increasing the optical brightness of the backlight module; a black metal brushed decorative film is directly adhered to the outside of the reflective layer 2 to protect the reflective coating, increase the aesthetics, and at the same time absorb the small amount of light leaked from the reflective layer 2, thereby achieving the effect of combining the conductive circuit board and the backplane into one.
