Description

Technical Field

[0001] This utility model belongs to the field of touch display technology, specifically a touch display module. Background Technology

[0002] As electronic devices continue to develop and become more widespread, touch modules, as key components for human-computer interaction, have received much attention for performance and structural optimization.

[0003] Traditional touch module structures often have limitations. For example, early resistive touch modules, while relatively simple in structure, suffered from limited resolution, low touch accuracy, and susceptibility to wear, making it difficult to meet the requirements of modern electronic devices for high-definition, sensitive touch, and durability. Capacitive touch modules utilize the capacitance change between the human body and electrodes to achieve touch sensing, offering better touch sensitivity and durability. However, due to their multi-layered design, their overall module thickness is relatively thick. For some electronic devices that prioritize thinness and lightness (such as high-end smartphones and tablets), integrating them presents challenges in terms of space occupation and potential impact on the overall thinness and lightness of the device.

[0004] Therefore, there is an urgent need in this field for an innovative touch display module structure that can overcome the inherent limitations of the above-mentioned technical routes and achieve breakthroughs in the thickness and weight of touch display modules without sacrificing performance, reliability and cost-effectiveness, so as to meet the needs of next-generation consumer electronics products. Utility Model Content

[0005] This utility model provides a touch display module that can adopt a zero-bonding cover plate, frame-bonded cover plate, or cover plate-free solution. It has the advantages of low process difficulty and high production efficiency, while achieving the requirements of thin and light touch screens based on traditional On-Cell structure.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A touch display module, comprising at least: Touch module: The touch module is a flexible touch module, including a first touch electrode and a second touch electrode; the second touch electrode is integrated into the display module and is located on the upper surface of the upper polarizer, the lower surface of the upper polarizer, or the upper surface of the color filter of the display module; a black border is provided around the first touch electrode, and the black border is located on the upper or lower surface of the first touch electrode; the touch module includes an FPC, and the touch chip and its peripheral circuit of the touch module are located on the T-CON board of the display module, and the FPC is connected to the T-CON board of the display module; First bonding adhesive: used to bond the first touch electrode and the display module; Display module.

[0007] Preferably, the touch module includes a cover plate and a second adhesive for bonding the cover plate to the first touch electrode. The cover plate is either a flexible cover plate or a rigid cover plate. Preferably, the cover plate is a flexible cover plate, using an AG base film or a hardened base film, with a hardness of at least 3H.

[0008] Preferably, a black border is provided around the cover plate, and the black border is provided on the upper or lower surface of the cover plate.

[0009] Preferably, the T-CON plates are arranged in a straight line or a back-folding manner.

[0010] Preferably, the total thickness of the first touch electrode and the first adhesive does not exceed 0.65 mm.

[0011] Preferably, the black border is formed by printing with black ink or by pasting with black adhesive material. The width of the black border is 0.1-40mm, the thickness of the black border formed by black ink is no more than 30μm, and the thickness of the black border formed by black adhesive material is no more than 100μm.

[0013] Preferably, the first touch electrode substrate is a functionalized base film. The functionalization of the base film includes one or more of the following: anti-glare, anti-fingerprint, anti-reflection, hardening, and anti-reflection. The functionalized layer of the base film is located on the non-conductive surface of the first touch electrode substrate, and its hardness is at least 1H.

[0014] Preferably, the flexible cover plate adopts a functionalized film, and the functionalization of the functionalized film includes one or more of the following: anti-glare, anti-fingerprint, anti-reflection, hardening, and anti-reflection. The functionalized layer of the functionalized film is located on the upper surface of the flexible cover plate.

[0015] Preferably, the size of the touch display module is 1-150 inches.

[0016] The touch display module adopts a coverless design, which reduces the use of a cover layer and effectively reduces the thickness of the touch display module. At the same time, the second touch electrode is integrated into the display module, which further reduces the thickness and weight of the touch display module.

[0017] In this invention, the non-conductive surface refers to the surface opposite the touch function layer of the touch electrode.

The thickness of the base film is 10-300 μm.

[0019] Touch display modules aim to integrate the advantages of traditional structures while overcoming their shortcomings, such as greater thickness, higher cost, or insufficient touch accuracy. Through innovative structural layouts and manufacturing processes, they achieve efficient and precise touch functionality within a more compact structure. Manufacturing processes can utilize semiconductor manufacturing technology, thin-film deposition technology, and photolithography technology, among others.

[0020] The adhesive used in this invention can be OCA optical adhesive, etc.

[0021] The system connection of a touch display module typically relies on a flexible printed circuit board (FPC). One end of the FPC is bonded to the touch sensor traces using anisotropic conductive adhesive (ACF), while the other end is connected to a timing controller board (T-CON). This FPC and T-CON configuration achieves higher space utilization, better structural stability, and lower overall cost while ensuring module performance and reliability.

[0022] Compared with the prior art, the technical effects of this utility model are as follows: 1. Compared with traditional touch modules, this utility model can effectively reduce the overall thickness of the module. This greatly saves internal space and helps the device achieve a thinner and lighter structural design while maintaining its original functions.

[0025] 4. This utility model has a simple structure. By simplifying some manufacturing processes and optimizing material usage, the production cost of the module can be reduced. While ensuring the quality of touch function, costs can be effectively controlled, thereby enhancing the market competitiveness of the product.
