In some manufacturing processes of the touch sensing display module, the frame can be narrowed or designed without the frame by bending the local thin film sensing structure 120, so that the display surface of the electronic product can be more attractive, and the display area can be increased. The detailed structure of the touch sensing display module 100 will be described first, and the manufacturing process of the touch sensing display module 100 in some embodiments will be described later.

The touch sensing display module 100 includes a substrate 110, a thin film sensing structure 120 and a display unit 130, wherein the thin film sensing structure 120 and the display unit 130 are located on the substrate 110 (Z-axis direction), and the thin film sensing structure 120 is located between the substrate 110 and the display unit 130.

In addition, in some embodiments, the film sensing structure 120 belongs to a part of an electronic product X100 (fig. 2B to fig. 2C), and the electronic product X100 further includes a functional element MS, wherein the functional element MS is disposed adjacent to the touch sensing display module 100 and can be disposed at an inner side of the substrate 110, the functional element MS is, for example, an optical component, further for example, the optical component can be, for example, an image pickup lens unit, an optical sensing element, an optical receiving element, and the like, and the other functional elements MS can also be, for example, structural components such as an antenna, a fixing element, a protruding element, and the like, which is not limited by the embodiment.

In addition, a shielding layer 110B may be disposed on the inner surface of the substrate 110 to define a peripheral area for shielding the peripheral circuit of the touch sensing display module 100 and the functional element MS of the electronic product. If the functional element MS is an optical component, in order to make the optical component operate normally, the substrate 110 may be configured with an optical hole 110H corresponding to the optical component through an offset or opening of the shielding layer 110B to provide an optical channel to prevent the shielding layer 110B from shielding the optical component. In some embodiments, the optical hole 110H is generally located near the upper edge of the touch-sensitive display module 100 in the Y-axis direction.

The display unit 130 can be used to display a frame for a user to view, the thin film sensing structure 120 can enable the touch sensing display module 100 to have a touch sensing function, and the user can touch the outer surface 110A of the substrate 110 (e.g., by hand or a touch pen) to achieve touch sensing.

The display unit 130 is used for displaying images, and may be a Liquid Crystal Display (LCD), a Light Emitting Diode (LED) display, or other types of suitable displays. The light emitting diode may include an Organic Light Emitting Diode (OLED), a submillimeter light emitting diode (mini LED), a micro LED, a Quantum Dot Light Emitting Diode (QDLED), and the like. For example, the present embodiment is described with reference to a liquid crystal display, the display unit 130 has a backlight component 131, a liquid crystal layer 132, a polarization component 133 and a display unit frame 134, wherein the backlight component 131, the backlight component 132 and the polarization component 133 are disposed in the display unit frame 134. In other embodiments, display unit 130 may include an alignment layer, an overcoat layer, a diffuser layer, or a brightness enhancement film to homogenize or brighten the light emitted by display unit 130.

With reference to fig. 2A to 2C, the thin film sensing structure 120 includes a main body 121 and a bending portion 122, the bending portion 122 is connected to at least one side of the main body 121, and the display unit 130 is sandwiched between the main body 121 and the bending portion 122 in the Z-axis direction. In detail, the display unit 130 has a front surface 130A, a back surface 130B opposite to the front surface 130A, and a side 130C connecting the front surface 130A and the back surface 130B, the main body 121 of the thin film sensing structure 120 is adjacent to the front surface 130A, and the bending portion 122 of the thin film sensing structure 120 is adjacent to the side 130C and the back surface 130B. The bending portion 122 extends from the front surface 130A to the rear surface 130B through the side 130C, and partially covers the side 130C and the rear surface 130B of the display unit 130.

It is noted that the bending portion 122 of the thin film sensing structure 120 is provided with a slot OP, and in the present embodiment, the slot OP is a through slot passing through the thin film sensing structure 120 and exposing a portion of the display unit 130. Specifically, the disposition position of the slot OP on the bending portion 122 is designed corresponding to the position of the functional element MS of the electronic product, so that by disposing the slot OP on the bending portion 122, the functional element MS of the electronic product and the bending portion 122 can be prevented from generating mechanism interference when the thin film sensing structure 120 is bent at the bending portion 122, and the mechanical layout or the subsequent production and assembly processes can be more flexible. In addition, since the peripheral leads of the thin film sensing structure 120 are disposed at the bending portion 122, after the bending portion 122 is bent to form a bending angle (e.g., 90 °) smaller than 180 ° with the body 121, the peripheral leads can be at least relatively disposed at the side 130C of the display unit 130, so that the disposing area of the shielding layer 110B of the substrate 110 can be relatively reduced, which is beneficial to the reduction of the border (border) of the display surface of the electronic product or the design of the borderless full screen.

It should be noted that the thin film sensing structure 120 may include at least one substrate (not shown) and at least one transparent sensing electrode layer (not shown) disposed on the substrate, for example.

In some embodiments, the stacked structure may be, for example, two transparent sensing electrode layers respectively disposed on the surfaces of different substrates, and then two substrates having the transparent sensing electrode layers formed thereon are bonded by an adhesive layer (not shown). Of course, the specific design of the stacked structure of the thin film sensing structure 120 of the present invention is not limited to the above structure.

Fig. 3A to 3E are flow charts showing a manufacturing process of a touch sensing display module according to an embodiment of the invention. It should be noted that, the present embodiment is used to describe the manufacturing method of the touch sensing display module, other functional elements of the electronic product are omitted, and reference may be actually made to the adjacent relationship between the touch sensing display module 100 and the functional element MS illustrated in fig. 2B and 2C. First, as shown in fig. 3A, a film sensing structure 120 is disposed on a release mold PF, wherein the release mold PF may be a release film, for example, to serve as a temporary carrier substrate, and a first optical adhesive OA1 is disposed on the film sensing structure 120. In some embodiments, if the film sensing structure 120 itself comprises a substrate that is sufficiently supportive in the manufacturing process, the release mold PF may not be needed, and the film sensing structure 120 is directly provided in the manufacturing process, and the first optical adhesive OA1 is disposed on the film sensing structure 120.

Next, as shown in FIG. 3B, a display unit 130 is disposed on the film sensing structure 120 via a first optical adhesive OA 1. The bending process is performed, as shown in fig. 3C, the film sensing structure 120 and the first optical adhesive OA1 are bent by a releasing mold PF, wherein in the present embodiment, the film sensing structure 120 provided with the first optical adhesive OA1 is illustrated by bending two opposite ends, that is, two opposite ends of the film sensing structure 120 have the bending portion 122, in other words, the two bending portions 122 in the present embodiment are connected to two opposite sides of the body 121. In the bending process, the bending portion 122 of the thin film sensing structure 120 extends from the front surface 130A of the display unit 130 to the back surface 130B through the side 130C, and covers a portion of the side 130C and the back surface 130B after bending, and the bending portion 122 has an L-shaped or C-shaped structure when viewed from the X-axis direction. In addition, the bent portion 122 of the film sensing structure 120 can be attached to the side 130C and the back surface 130B of the display unit 130 by the first optical adhesive OA 1.

Continuing to refer to fig. 3D, the release mold PF is released from the bent film sensing structure 120 (at least partially covering the display unit 130), and the film sensing structure 120 is disposed on a substrate 110, wherein the film sensing structure 120 is connected to the substrate 110 by a second optical adhesive OA 2. Thus, the bent thin film sensing structure 120 is disposed on the substrate 110, as shown in fig. 3E.

In other embodiments, at least one end of the thin film sensing structure 120 has a bending portion 122, that is, the bending portion 122 is connected to one side of the body 121, as shown in fig. 2C, so that the thin film sensing structure 120 has an L-shaped structure.

It should be noted that the bending portion 122 of the thin film sensing structure 120 has the slot OP, that is, the thickness of the thin film sensing structure 120 is not existed at the slot OP, so that the functional element MS of the electronic product corresponding to the slot OP can avoid the bending interference and the assembly interference with the thin film sensing structure 120, in other words, the bending portion 122 has the slot OP, so that the assembly of the thin film sensing structure 120, the substrate 110, and the functional element MS of the electronic product can be easier, and in addition, the thickness of the thin film sensing structure 120 is not existed at the slot OP, so that the distance between the other functional element MS and the thin film sensing structure 120 can be greatly reduced, that is, a space does not need to be specially vacated to avoid the interference between the two, so as to effectively solve the interference problem between the elements. In addition, the bending portion 122 extends from the front surface 130A to the rear surface 130B of the display unit 130 and covers a side 130C of the display unit 130, which is beneficial to the adhesion between the film sensing structure 120 and the display unit 130 and improves the reliability of the device.
