Description

monitor

technical field

The present invention relates to a display, and more particularly to a display which is not easily damaged during heavy work.

Background technique

With the development of the industry, digital tools such as mobile phones, digital cameras, digital video cameras, notebook computers (notebooks) and desktop computers are all more convenient, multi-functional and development in an aesthetic direction. When using these information products, the display screen is an indispensable human-machine communication interface. The display screen of the above-mentioned products will bring more convenience to the user's operation. Among them, liquid crystal displays have become the mainstream of display screens. However, since the liquid crystal display panel of the liquid crystal display cannot emit light, a backlight module must be provided under the liquid crystal display panel to provide a light source to achieve the display function.

FIG. 1 is a schematic cross-sectional view of a conventional liquid crystal display. Referring to FIG. 1 , a conventional liquid crystal display 10 includes a front frame 11 , a liquid crystal display panel 12 , a double-sided adhesive material 13 and a backlight module 14 . Wherein, the liquid crystal display panel 12 is disposed between the front frame 11 and the backlight module 14 , and the liquid crystal display panel 12 is adhered to the backlight module 14 by a double-sided adhesive material 13 . More specifically, the backlight module 14 is a side-illuminated backlight module, and the backlight module 14 includes a plastic frame 14a, a light guide plate 14b, a light tube 14c, and a back plate 14d. Wherein, the plastic frame 14a is disposed on the back plate 14d, and the liquid crystal display panel 12 is glued on the plastic frame 14a by the double-sided adhesive material 13 . In addition, the light guide plate 14b is disposed above the back plate 14d and located in the plastic frame 14a. The lamp tube 14c is disposed above the back plate 14d and located on one side of the light guide plate 14b.

Generally speaking, after the backlight module 10 is assembled, a drop test must be performed to ensure product quality. During the drop test, in order to prevent the liquid crystal display panel 12 from colliding with the front frame 11 and causing cracks, the liquid crystal display panel 12 is usually glued to the glue frame 14a of the backlight module 14 by a double-sided adhesive material 13 .

During the manufacturing process of the liquid crystal display 10 , some defects inevitably occur, such as damage to the backlight module 14 . At this time, it is necessary to carry out rework steps, dismantle the front frame 11 and the liquid crystal display panel 12 in sequence, and then reassemble these components after checking and repairing the backlight module 14 . However, since the liquid crystal display panel 12 is adhered to the backlight module 14 by the double-sided adhesive material 13 , the liquid crystal display panel 12 or the backlight module 14 are easily damaged when the liquid crystal display panel 12 is removed. In other words, the rework yield of the liquid crystal display 10 is not good.

Detailed ways

FIG. 2A is a schematic cross-sectional view of the structure of a display according to an embodiment of the present invention, and FIG. 2B is a perspective view of a spacer and a backlight module of the display in FIG. 2A . Please refer to FIG. 2A and FIG. 2B at the same time. The display 100 of this embodiment includes a backlight module 110 , a spacer 120 , a display panel 130 and a front frame 140 . Wherein, the gasket 120 is disposed on the backlight module 110 , and the display panel 130 is fixed on the gasket 120 . In addition, the front frame 140 is assembled with the backlight module 110 to clamp the display panel 130 .

In more detail, the display panel 130 is, for example, a transmissive liquid crystal display panel, a transflective liquid crystal display panel or other suitable panels. In addition, the backlight module 110 of this embodiment is a side-lit backlight module, but the backlight module 110 of this embodiment may also be a direct-lit backlight module. The backlight module 110 of this embodiment has a plastic frame 112, and the plastic frame 112 has at least one protruding portion 112a. Similarly, the spacer 120 has at least one opening 120a, and the spacer 120 is disposed on the plastic frame 112, and the protrusion 112a of the plastic frame 112 passes through the opening 120a, so that the spacer 120 can be fixed on the plastic frame 112 superior. In other embodiments, the spacer 120 in FIG. 2B can be divided into four or more discontinuous sheet-like or strip-like structures according to four sides.

As shown in FIG. 2A, in this embodiment, the display 100 further includes an adhesive layer 150, and the adhesive layer 150 is disposed between the gasket 120 and the display panel 130, so the display panel 130 is adhered to the display panel 130 through the adhesive layer 150. Gasket 120 on. In addition, when the backlight module 110 of this embodiment is a side-illuminated backlight module, the backlight module 110 further includes a light guide plate 114 and at least one light source 116 . Wherein, the light guide plate 114 is disposed under the display panel 116 and located in the plastic frame 112 . In addition, the light source 116 is disposed on one side of the light guide plate 112 and located in the plastic frame 112 . In addition to the above components, the backlight module 110 in this embodiment may further include a back plate 118 disposed under the plastic frame 112 and the light guide plate 114 . It should be noted that, in another embodiment, the backlight module (not shown) may also not include the backplane according to different requirements.

In addition, in order to prevent the display panel 100 from shaking, the spacer 120 will slide along the protruding portion 112 a to make the display panel 130 collide with the front frame 140 . Therefore, in the display 100 , the spacer 120 may also have at least one supporting rib 122 . The supporting rib 122 is located at the edge of the opening 120a, and one end of the supporting rib 122 is in contact with the front frame 140 . It is worth mentioning that, in this embodiment, the supporting rib 122 is integrally formed with the spacer 120 . However, the supporting rib 122 and the spacer 120 may also be separate components.

Generally speaking, during the manufacturing process of the display 100, some defects inevitably occur. If the backlight module 110 is defective, a rework step must be performed to disassemble each component so as to inspect the backlight module 110 . After checking and repairing the backlight module 110, these components will be reassembled. At this time, in the display 100 of this embodiment, since the display panel 130 is adhered to the spacer 120 through the adhesive layer 150, compared with the conventional technology, the display panel 130 of the display 100 of this embodiment is easier to disassemble. Solution, simply remove the display panel 130 and the spacer 120 at the same time. In this way, the display panel 130 or the backlight module 110 of the display 100 in this embodiment are less likely to be damaged due to improper disassembly, and the rework yield of the display 100 can also be effectively improved.

It is worth noting that although the present embodiment uses the backlight module 110 as a side-light type backlight module for illustration, in other embodiments, the backlight module can also be a direct-type backlight module, light-emitting diode Body backlight module, cold cathode light flat light backlight module, organic electroluminescence backlight module or other appropriate backlight modules.

To sum up, since the present invention fixes the display panel on the spacer, and the display panel and the spacer are then assembled with the backlight module, the display panel can be easily removed without damaging the display panel during rework steps or backlight module. In other words, the display of the present invention is not only less prone to damage during rework, but also the rework yield can be improved.

Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, this The scope of protection of the invention should be defined by the claims.
