Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to an OLED display screen structure with alignment marks. Background Art

[0002] With the continuous development of technology, organic light-emitting diode (OLED) display screens have occupied an important position in the display field due to their excellent color performance, high contrast, fast response, and ultra-thin design.

[0003] Conventionally, a polarizer is usually added to the glass surface of an OLED screen. The function of the polarizer is to decompose the reflected light into linearly polarized light, thereby reducing the interference of the reflected light on the display effect and improving the display contrast. At the same time, due to the ONCELL structure, a touch FPC also needs to be bonded to the display screen glass. Since the bonding position of the touch FPC is relatively close to the position of the polarizer, if the polarizer is pasted with too much deviation, it cannot be detected in time, which will affect the bonding effect of the touch FPC.

[0004] In view of the above, an OLED display screen structure with alignment marks is proposed to avoid the deviation of the polarizer from affecting the bonding effect of the touch FPC. Summary of the Utility Model

[0026] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.

[0027] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, an OLED display screen structure with alignment marks includes: a display screen body 100, a polarizer 200, a touch FPC 300 and an alignment member 400. A first binding position and a polarizer attachment area are provided on the display screen body 100, and the first binding position and the polarizer attachment area are located on the same side; the polarizer 400 is attached to the polarizer attachment area; the touch FPC is bound to the first binding position, and the side of the polarizer attachment area close to the first binding position is an attachment boundary area; the alignment member 400 includes a first alignment mark 410, the first alignment mark 410 is provided on the display screen body 100, and the first alignment mark 410 is located on the attachment boundary area, and the first alignment mark 410 is used for the alignment and fitting of the polarizer 200.

[0028] It should be noted that since the polarizer attachment area is adjacent to the first binding position and is relatively close, in order to avoid a large deviation in the attachment position of the polarizer 200, which may interfere with the normal attachment of the interference touch FPC (flexible printed circuit board), a positioning member 400 is provided on the attachment boundary area. Specifically, the alignment of the polarizer 200 is achieved through the first alignment mark 410 to avoid excessive misalignment during attachment. At the same time, through the first alignment mark 410, it can also be determined whether the polarizer 200 has a large position shift, thereby avoiding excessive misalignment of the polarizer 200 during attachment, which may affect the binding effect of the subsequent touch FPC 300. Specifically, please refer to Figure 2 As shown, if the edge of the polarizer 200 is within the width range of the first alignment mark, that is, the first alignment mark 410 is partially covered by the polarizer, it is determined that the attachment position is qualified; please refer to Figure 3 As shown, if the edge of the polarizer 200 completely exceeds the first alignment mark 410, that is, the first alignment mark 410 is completely exposed, then it is determined that the attachment position is unqualified; please refer to Figure 4 As shown, if the polarizer 200 completely covers the first alignment mark 410, it is determined that the attachment position is unqualified.

[0029] Specifically, the first alignment mark 410 includes a first central alignment line 411, and the first central alignment line 411 is located on the attachment boundary area. Whether the polarizer 200 has a large position shift is determined through the first central alignment line 411, thereby ensuring the bonding quality of the touch FPC 300.

[0030] In another embodiment, please refer to Figure 5 and Figure 6 As shown, the first alignment mark 410 further includes two first limiting lines 412, and the two first limiting lines 412 are respectively located on both sides of the first central alignment line 411. In this way, by adding the first limiting lines 412, if the edge of the polarizer 200 is between the two first limiting lines 412, it is determined that the attachment position of the polarizer 200 is qualified.

[0031] Furthermore, the first alignment mark 410 further includes two first precision lines 413. The two first precision lines 413 are respectively located on both sides of the first central alignment line 411, and the two first limiting lines 412 are respectively located between the two first precision lines 413. That is, through the first central alignment line 411, the first limiting lines 412 and the first precision lines 413, the corresponding device can conveniently detect the size of the polarizer misalignment, so as to facilitate timely adjustment and correction of the machine.

[0032] Furthermore, the width value range of the first central alignment line 411 is 0.01 mm - 0.05 mm. That is, the width of the first central alignment line 411 can be designed in a matching manner according to the needs of the product project, that is, the width of the first central alignment line 411 is selected according to the allowable misalignment amount of the polarizer 200.

[0033] Further, the distance between the first central alignment line 411 and one of the first limit lines 412 is 50 μm. That is, 50 μm is the allowable deviation amount of the polarizer 200. The first limit line 412 is the deviation limit of the polarizer 200.

[0034] Further, the distance between the first central alignment line 411 and one of the first precision lines 413 is 100 μm. In this way, it is convenient for the corresponding device to detect the size of the deviation of the polarizer, so as to facilitate timely adjustment of the machine for correction.

[0035] In one embodiment, the first alignment mark 410 is a metal alignment mark or an ink alignment mark. For example, the ink alignment mark can be a black ink alignment mark to facilitate mark grabbing and identification.

[0036] In one embodiment, the alignment member 400 further includes a second alignment mark, and the second alignment mark is disposed on the attachment boundary area, and the second alignment mark and the first alignment mark are respectively located on both side edges close to the display screen body. That is, the first alignment mark 410 and the second alignment mark are symmetric about the central symmetry axis of the display screen body, achieving left-right symmetry, thereby making the alignment and attachment operation of the polarizer more convenient.

[0037] Preferably, the structure of the first alignment mark 410 is the same as that of the second alignment mark.

[0038] The above-described embodiments merely represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
