[0025] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0026] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0027] In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", and "third" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0028] The utility model provides an AMOLED screen for preventing a driver IC from being scratched, comprising an upper substrate, a lower substrate, a first FPC and a driver IC, wherein the lower substrate is arranged below the upper substrate, the lower substrate is longer than the upper substrate and extends outward to form a step; the first FPC is bound to the upper surface of the lower substrate located at the step; the driver IC is bound to the lower surface of the first FPC, the first FPC is bent outwardly and the driver IC is bent to the bottom of the lower substrate, and after bending, the driver IC is located between the first FPC and the lower substrate.

[0029] In traditional AMOLED screens, the driver IC is usually bound to the upper surface of the first FPC. When the first FPC is bent to the back of the lower substrate, the driver IC is exposed to the outside, that is, in the operator's field of vision. Since the driver IC is exposed to the surface, during operation, various external factors such as electrical testing, transportation and storage will directly cause direct damage to the driver IC on the COF. This solution binds the driver IC to the lower surface of the first FPC. After the first FPC is bent, the driver IC can be located between the first FPC and the lower substrate, so that the driver IC will not be exposed to the outside, thereby protecting the driver IC from scratches and improving the competitiveness of the product.

[0030] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The present invention is described in detail below in conjunction with the accompanying drawings and embodiments, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention.

[0031] See also Figures 1 to 3 , an AMOLED screen for preventing driver IC from being scratched provided by the utility model, comprising an upper substrate 1, a lower substrate 2, a first FPC3 and a driver IC4, wherein the lower substrate 2 is arranged below the upper substrate 1, and the lower substrate 2 is longer than the upper substrate 1 and extends outward to form a step; the first FPC3 is bound to the upper surface of the lower substrate 2 located at the step; the driver IC4 is bound to the lower surface of the first FPC3, the first FPC3 is bent outward, and the driver IC4 is bent to the bottom of the lower substrate 2, and after bending, the driver IC4 is located between the first FPC3 and the lower substrate 2. In a traditional AMOLED screen, the driver IC4 is generally bound to the upper surface of the first FPC3, and when the first FPC3 is bent to the back of the lower substrate 2, the driver IC4 is exposed to the outside, that is, in the field of vision of the operator. Since the driver IC4 is exposed to the surface, during the operation, various external factors such as electrical measurement, handling and storage will directly cause direct damage to the driver IC4 on the COF. In this solution, the driver IC4 is bound to the lower surface of the first FPC3. After the first FPC3 is bent, the driver IC4 can be located between the first FPC3 and the lower substrate 2, so that the driver IC4 will not be exposed to the outside, thereby protecting the driver IC4 from scratches and improving the competitiveness of the product.

[0032] Furthermore, the thickness of the driver IC 4 is 0.38 mm.

The reinforcing plate 52 is fixed to the upper surface of the end of the body 51, and both ends of the reinforcing plate 52 have fixed parts 54 extending outward, and the two fixed parts 54 are beyond the edge of the body 51. The lower surfaces of the two fixed parts 54 are fixed with first strong magnetic blocks 55; the connector 53 is arranged below the body 51, and two second strong magnetic blocks 56 corresponding to the two first strong magnetic blocks 55 are fixed to the connector 53. Since the upper surface of the body 51 is fixed with a reinforcing plate 52, both ends of the reinforcing plate 52 are fixed with first strong magnetic blocks 55, and the connector 53 is fixed with two second strong magnetic blocks 56 corresponding to the two first strong magnetic blocks 55, when the body 51 and the connector 53 are installed, as long as the two ends of the body 51 are close to the connector 53, the first strong magnetic blocks 55 at both ends of the body 51 and the second strong magnetic blocks 56 at both ends of the connector 53 will attract each other and be fixed, and the body 51 and the connector 53 can be automatically aligned and tightly connected. This assembly structure of the second FPC 5 has few assembly steps, and only the body 51 needs to be placed close to the connector 53. 1 can be assembled by being close to the connector 53, the assembly efficiency of the second FPC5 can be greatly improved, and the automatic assembly of the second FPC5 and the connector 53 can be easily realized. The fewer the assembly steps, the lower the probability of defective products of the second FPC5 during assembly, thereby avoiding the situation that the products assembled with it cannot work normally due to poor assembly, thereby avoiding abnormal operation of the product, reducing the defective rate of the product, and thus greatly reducing the production and manufacturing cost of the second FPC5, thereby improving the product competitiveness of the second FPC5, so as to meet the growing quality requirements of enterprises.

[0034] Furthermore, two grooves 57 are provided on the connector 53, and two second strong magnetic blocks 56 are respectively fixed in the two grooves 57, so that the fit between the main body 51 and the connector 53 is more compact, and the reliability of assembly is improved, thereby greatly reducing the production and manufacturing costs of the second FPC5, and further improving the product competitiveness of the second FPC5, so as to meet the company's growing quality requirements.

[0035] Furthermore, the edge of the groove 57 is provided with a chamfer, and more preferably, the chamfer is a right angle or a rounded angle, so that when the first strong magnetic block 55 is close to the second strong magnetic block 56, it can fall accurately into the groove 57 under the guidance of the chamfer, thereby improving the accuracy and reliability of assembly, thereby greatly reducing the production and manufacturing costs of the second FPC5, and further improving the product competitiveness of the second FPC5.

[0036] Furthermore, the outer dimensions of the second strong magnetic block 56 are larger than those of the first strong magnetic block 55, and the outer dimensions of the groove 57 correspond to those of the first strong magnetic block 55 and the second strong magnetic block 56, so that the second strong magnetic block 56 can be firmly fixed in the groove 57. Even if the suction force of the first strong magnetic block 55 is large, the second strong magnetic block 56 will not be sucked out, thereby improving the reliability of assembly, thereby greatly reducing the production and manufacturing costs of the second FPC5, and further improving the product competitiveness of the second FPC5, thereby meeting the company's growing quality requirements.

[0037] Furthermore, the depth of the groove 57 is equal to the sum of the thicknesses of the first strong magnetic block 55 and the second strong magnetic block 56, so that the assembly of the body 51 and the connector 53 can be smoothly fitted without leaving any gaps. More preferably, a buffer pad can be provided on the contact surface between the body 51 and the connector 53, and a buffer groove corresponding to the buffer pad is provided on the connector 53, so that the body 51 or the connector 53 can be cushioned during the fitting assembly to avoid damage to the body 51 or the connector 53. More preferably, the buffer pad is a rubber pad, which has good effect, low cost and high cost performance.

[0038] Furthermore, the materials of the first strong magnetic block 55 and the second strong magnetic block 56 are both NdFeB strong magnets, which have mature technology and high cost performance.

[0039] Furthermore, the first strong magnetic block 55 and the second strong magnetic block 56 have different colors so that the staff can distinguish the first strong magnetic block 55 and the second strong magnetic block 56 during installation.
