[0031] Since the display FPC located in the binding area is in a concave shape, a notch is formed in the concave display FPC, and the backlight FPC passes through the notch from the bottom of the display FPC and is bound to the binding pad, thereby changing the traditional solution of a protruding portion of the display FPC to a notch on the left or right side of the display FPC, thereby reducing the notch area on the left or right side of the display FPC, thereby increasing the area where the display FPC can be wired.

[0032] 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 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.
[0033] Example 1

In this embodiment, the notch 21 is located on the right side of the bottom of the display module 200, that is, on the right side of the display FPC2, and a binding pad 22 is provided on the upper surface of the display FPC2, and the binding pad 22 is located near the notch 21 and away from the display binding position. The backlight FPC1 passes through the notch 21 from the bottom of the display FPC2 and is bound to the binding pad 22. Since the display FPC2 located in the binding area is in a concave shape, a notch 21 is formed in the concave display FPC2, and the backlight FPC1 passes through the notch 21 from the bottom of the display FPC2 and is bound to the binding pad 22, thereby changing the scheme in which a part of the display FPC2 protrudes out in the traditional scheme to open a notch 21 on the left or right side of the display FPC2, thereby reducing the area of the notch 21 on the left or right side of the display FPC2, thereby increasing the area where the display FPC2 can be wired, and at this time, the maximum width of the display FPC2 can be appropriately reduced and the same area can be used for wiring, thereby reducing the occupied area of the display FPC2, and reducing the area where the terminal design avoids the display FPC2, thereby reducing the cost of the display FPC2 and improving the competitiveness of the product.
[0035] Furthermore, the number of pins bound to the backlight FPC1 is 2, 3, 4 or more than 4, and the specific number can be set as needed according to actual needs.
[0036] Example 2
[0037] See also Figures 4 to 6As a further optimization scheme of Example 1, in this embodiment, the display module 200 includes a lower polarizer 3, a lower substrate 4, an upper substrate 5 and an upper polarizer 6 which are sequentially stacked from bottom to top. The lower substrate 4 is longer than the upper substrate 5 and forms a step. The upper surface of the lower substrate 4 located at the step is bound with a driver IC 7 and a display FPC 2. The driver IC 7 is in the shape of a quadrangular pyramid. The upper surface of the lower substrate 4 located at the step is coated with a protective glue 8, and the protective glue 8 completely covers the side and the step of the driver IC 7. This allows the surroundings of the driver IC 7 to effectively increase the coverage area of the protective glue 8 covering the driver IC 7, thereby avoiding the risk of gaps around the driver IC 7, thereby effectively preventing water vapor or salt mist from penetrating into the binding position between the driver IC 7 and the lower substrate 4, and then avoiding the driver IC 7 from having a short circuit, a large current or a circuit breaker, etc., which leads to abnormal display, thereby reducing the defective rate of the product, thereby reducing the manufacturing cost of the product, and making the product fully competitive to meet the growing quality requirements of the production enterprises.
[0038] Furthermore, chamfers are provided at the corners of the driver IC 7. Preferably, the chamfers are right angles or rounded corners to further increase the coverage area of the protective glue 8.
[0039] Furthermore, a protrusion 41 is provided at the edge of the upper surface of the lower substrate 4 located at the step, and the protrusion 41 can be used to limit the flow of the protective glue 8, thereby preventing the protective glue 8 from overflowing to other places.
[0040] Furthermore, the upper surface of the protrusion 41 is flush with the upper surface of the upper substrate 5 .
[0041] Furthermore, a chamfer is provided at the connection between the protrusion 41 and the lower substrate 4 so that the protective glue 8 can better cover the upper surface of the lower substrate 4 to avoid the generation of bubbles.
[0042] Furthermore, the protrusion 41 is formed integrally with the lower substrate 4 to reduce product cost and improve product competitiveness.
