Description

Display device

Technical Field

The application relates to the technical field of display, in particular to a display device.

Background

In four-sided borderless backlight modules, the thickness of the printed circuit board COVER (PCB COVER) on the Chip On Film (COF) side is generally smaller due to the limitation of the size of the bezel, resulting in a smaller structural strength of the PCB COVER. When COF and the adhesive frame are attached through the PCB COVER, the situation that gaps are larger due to the fact that attaching is not tight easily occurs among the COF, the adhesive frame and the three. The main reason for the poor bonding of the three is that the curved COF is not easy to deform, and the part of the structure of the PCB COVER on the COF side is ejected and deformed. The poor adhesion between the PCB COVER, the COF and the adhesive frame can lead to the widening of the frame of the backlight module, and the COF cannot be effectively protected.

In addition, the present application provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the application of other processes and/or the use of other materials.

Fig. 1 provides a schematic view of a partial cross-sectional structure of an exemplary display device. As can be seen from fig. 1, the display device 1 includes a display panel 2, a frame 3, a backlight unit 4, a circuit film (e.g., a chip on film COF) 5, a circuit COVER (e.g., a PCB COVER) 6, and a housing 7. Wherein, the glue frame 3, the backlight unit 4, the circuit film 5 and the circuit cover plate 6 form a four-side borderless backlight module.

Specifically, the rubber frame 3 includes a first support portion 3a and a second support portion 3b that are vertically connected; wherein the first supporting part 3a is positioned on the back surface of the display panel 2 and is jointed with the display panel 2 through a jointing layer for supporting the display panel 2; the second support portion 3b is vertically connected to one end of the first support portion 3a near the side surface of the display panel 2.

Specifically, the circuit film 5 is sandwiched between the display panel 2 and the first support portion 3a, and extends to a side of the second support portion 3b away from the backlight unit 4 and a side of the second support portion 3b away from the first support portion 3 a.

Specifically, the circuit cover plate 6 includes a first sub-cover plate 6a and a second sub-cover plate 6b that are integrally formed; the first sub-cover plate 6a is located on a side surface of the display panel 2 and corresponds to the second supporting portion 3b, and the second sub-cover plate 6b is vertically connected with one end of the first sub-cover plate 6a away from the display panel 2. The first sub-cover plate 6a and the second sub-cover plate 6b are covered on the circuit film 5 and used for realizing the joint arrangement of the circuit film 5 and the rubber frame 3 and isolating the circuit film 5 from the external environment, so that the circuit film 5 is not only beneficial to realizing narrow frame, but also can be protected from being corroded and damaged.

Specifically, the backlight unit 4 is located in a receiving cavity formed by the adhesive frame 3 and the circuit cover plate 6. The housing 7 is integrally provided and is located outside the circuit cover plate 6 and the backlight unit 4.

It can be understood that the circuit film 5 in fig. 1 is disposed on the surfaces of the first supporting portion 3a and the second supporting portion 3b of the adhesive frame 3 after two bends. However, the curved circuit film 5 is not easy to deform, so that the structure of the circuit cover plate 6 attached to the circuit film 5 is ejected and deformed outwards, and the circuit cover plate 6, the circuit film 5 and the adhesive frame 3 are not tightly attached to each other. However, the circuit cover plate 6, the circuit film 5 and the adhesive frame 3 are not tightly adhered, which leads to widening of the frame of the display device 1, and the circuit film 5 is not effectively protected.

Meanwhile, when the four-sided borderless backlight module and the housing 7 are assembled into the display device 1, the backlight module and the housing 7 are usually fixed by two ways of strong magnet and screw locking on the housing 7. However, the backlight module is at risk of falling off from the housing by means of the powerful magnet, and the screw locking manner makes the top side and the bottom side of the housing 7 consume a certain number of bolts, which results in inconvenient assembly and high cost.
