Description

[Technical Field]

[0001] This invention relates to a display device, and more particularly to a display device having a barbed shell structure that can replace the use of a frame to fix an optical material assembly, and a method thereof for assembling the display device. [Previous Technology]

[0002] Existing display devices typically include a display panel, a backlight module, and a housing. The backlight module mainly consists of an outer frame, an inner frame, and optical materials. The inner frame supports the optical materials (such as light guide plates and optical sheets), while the outer frame is used to fix these optical materials and provide a supporting structure for the panel. This separate design not only makes the assembly structure more complex but also increases the weight and thickness of the device, making it difficult to meet the modern display device's demand for thinner and lighter designs.

[0003] To reduce the thickness of displays, the number of components, and costs, the industry has developed integrated displays that place the optical material assembly directly inside the display housing, with barbs inside the housing to prevent the optical material assembly from jumping out. However, due to the small installation gap between the housing and the optical material, scratches are prone to occur during assembly, affecting the integrity and function of the optical material. On the other hand, if the gap between the optical material and the housing is too large, the optical material may shift or fall off during use, further reducing the fixing effect of the display device. [Summary of the Invention]

[0004] The present invention provides a display device having a housing with a special fixing structure to fix optical materials and a support panel, replacing a heavy fixing frame, and providing a distance between the optical materials and the fixing structure to prevent scratches.

[0005] In view of the above, the present invention provides a display device having an optical material assembly, a panel, and a housing, characterized in that the optical material assembly comprises: a plurality of optical materials; and an auxiliary mounting piece, the optical materials being disposed on the upper surface of the auxiliary mounting piece; the housing comprises: a base plate, the optical material assembly being disposed on the upper surface of the base plate; a side wall, erected on one side of the base plate, located on one side of the optical material assembly; and a barb structure having a vertical wall and a fixing part, the vertical wall being erected on the other side of the base plate, and the fixing part extending outward from the top of the vertical wall and located above the optical material assembly, the upper surface of the fixing part and the upper surface of the side wall supporting the panel; wherein the upper surface of the base plate and the lower surface of the auxiliary mounting piece are adjacent to the barb structure and are separated from each other by a distance ≥0.3 mm.

[0006] Where the base plate meets the vertical wall, there is a groove. The groove is provided along the extension direction of the fixing part, and the depth of the groove is ≥0.3 mm.

[0007] The lower surface of the optical material group is uniformly provided with a plurality of support blocks, the thickness of which is ≥0.3 mm.

[0008] The width of the fixing part is 1~4 mm.

[0009] The vertical distance between the fixing part and the optical material group is 0.1~0.4 mm.

[0010] The present invention also provides a method for assembling a display device, comprising: fixing a plurality of optical materials to the upper surface of an auxiliary mounting plate to form an optical material group; inserting the optical material group into a housing at an angle, the direction of the angled insertion being toward a barb structure of the housing; and mounting a panel above the optical material group, such that the barb structure and a side wall of the housing abut against the lower surface of the panel.

[0011] In the process of the optical material group being obliquely inserted into the housing, the straight distance between a fixing part of the barb structure and the optical material group is ≥0.4 mm.

[0012] The angle is calculated according to the following formula: where is the angle, H is the vertical distance between the fixing part and the optical material group after the display device is assembled, and W is the straight distance between the fixing part and the optical material group during the oblique insertion installation process.

Implementation Method

[0013] In order to make the description of this disclosure detailed and complete, specific embodiments and specific examples of the present invention are described, but they are not the only forms of implementing or using the specific examples of the present invention. Other specific examples can be used to achieve the same or equivalent functions and steps.

[0014] The descriptions of directions such as "front", "back", "up", "down", "left", and "right" mentioned in this article are only for ease of understanding. This invention is not limited to these directions, but can be adjusted according to the actual situation.

[0015] See FIG. The sidewall 12 is vertically positioned upright on one of the sides of the base plate 11. The optical material group 20 is disposed above the base plate 11 adjacent to the side wall 12. In this embodiment, a plurality of light sources 30 is fixed on the side adjacent to the side wall 12 as a side-entry light source.

[0016] The inverted hook structure 13 comprises a standing wall 131 as well as a fixing portion 132 that is vertically positioned upright on the other side of the base plate 11 , such that the optical material group 20 is sandwiched between the standing wall 131 and the side wall 12 , the fixing portion 1 32 extends outward from the apex of the standing wall 131 and is located above the group of optical materials 20, the fixation 132 parallel to the base plate 11 and the panel 40 disposed above the group 20 by virtue of being attached to the side wall 12 and the fixing portion 132 . Wherein, the width A of the fixing portion 132 is 1~4 mm, and the vertical distance H of the fixing portion 132 and the optical material group 20 is 0.1~0.4 mm, which prevents the optical material group 20 from detaching from the shell 10 during thermal expansion or contraction or vibration of the display device. In addition, the base plate 11 also has a groove 14 extending along the extension direction of the fixing portion 132 , wherein the groove 14 has a depth d≧0.3 mm, near the standing wall 131 .

[0017] Please refer to Figure 2, which is an assembly diagram of the above embodiment. The optical material assembly 20 has an auxiliary mounting piece 21, a plurality of double-sided adhesive tapes 22, a plurality of optical films 23, a plurality of reflectors 24, and a light guide plate 25. First, the double-sided adhesive tapes 22 are evenly adhered to the lower surface of the auxiliary mounting piece 21. Then, the light guide plate 25 and the optical films 23 are sequentially stacked and fixed on the upper surface of the auxiliary mounting piece 21. The reflectors 24 are disposed around the light guide plate 25 and / or between it and the auxiliary mounting piece 21. Due to the barbed structure 13 design of the housing 10, the assembled optical material assembly 20 needs to be obliquely inserted into the housing 10 at an angle θ. The oblique insertion direction is towards the groove 14. During the oblique insertion process, the groove 14 can provide a straight distance W ≥ 0.4 between the optical material assembly 20 and the fixing part 132. mm, thereby preventing the fixing part 132 from wearing down the optical material assembly 20 during assembly, and the angle of the oblique installation. After the optical material assembly 20 is installed and parallel to the base plate 11, gently press the optical material assembly 20 to make the double-sided adhesive 22 on the bottom stick to the base plate 11. Finally, attach the panel 40 on top of the optical material assembly 20 to complete the display device.

[0018] Next, in addition to providing a safe distance W during the assembly process through the groove 14 and limiting the vertical distance H of the position of the optical material group 20 by the fixing part 132, the same effect can also be achieved through a plurality of support blocks 26. Please refer to Figures 3 and 4 for schematic diagrams of another embodiment of the present invention. Similarly, the display device includes a housing 10, an optical material assembly 20, and a panel 40. The housing 10 also has a barb structure 13 to maintain the position of the optical material assembly 20 within the housing 10. The lower surface of the optical material assembly 20 is uniformly provided with support blocks 26, the thickness of which is d ≥ 0.3 mm. To achieve the same effect as in the first embodiment, the support blocks 26 are only disposed on the lower surface of the optical material assembly 20 away from the barb structure 13 and above the inner surface of the housing 10. This ensures that during the process of the optical material assembly 20 being obliquely inserted into the housing 10, the distance W between it and the fixing part 132 is ≥ 0.4 mm, and after installation, the vertical distance H between the optical material assembly 20 and the fixing part 132 is 0.1~0.4 mm. Since the assembly steps of this embodiment are similar to those described above, they will not be repeated here.

[0019] The display device of the present invention has a housing 10 with a barb structure 13 to hold the optical material assembly 20 in the housing 10. At the same time, through the groove 14 of the housing 10 or the support blocks 26 provided on the lower surface of the optical material assembly 20, a safe distance W between the optical material assembly 20 and the housing 10 is provided during the assembly process to prevent the optical material assembly 20 from being worn and affecting its function. In addition, the design of the display device of the present invention can replace the old fixed frame to fix the optical material, effectively reducing the overall weight and size, and meeting the modern demand for lightweight devices.
