[0030] Liquid crystal displays (LCDs) are widely used in our daily lives, for example, as display screens for mobile phones, computers, and televisions. With the development of display technology and people's demand for more advanced display technology, narrow-frame LCDs are becoming a new generation trend.

[0031] Figure 1 The diagram shows the hierarchical structure of a conventional liquid crystal display module. Figure 1 As shown, from bottom to top, there are the first polarizer POL1, the first substrate for arranging the thin film transistor TFT (in Figure 1 TFT in the figure), a first alignment film PI1, a liquid crystal layer LCD, a black matrix layer BM, a second alignment film PI2, a second substrate for arranging a color filter CF (in the figure), Figure 1 Due to the TFT array design on the first substrate, the gates of each row of TFTs in the array are driven simultaneously by one gate line. The gate driving circuit is used to drive different gate lines to refresh the display panel. Therefore, a gate driving circuit is required to be provided for each gate line to control the corresponding gate. Figure 1 The shaded portion in the figure shows the space currently occupied by the gate driver circuit when it is disposed on the first substrate. It should be noted that, generally speaking, the gate driver circuit is disposed in the peripheral area of ​​the display panel, and is typically disposed in the peripheral area on the left and / or right sides of the display panel. In other words, the border width that is desired to be reduced in the embodiments of the present disclosure refers to the border width on the left and right sides of the display panel.

[0032] To address the aforementioned issues, the first embodiment of the present disclosure provides a liquid crystal display module that is functionally divided into a display area and a peripheral area surrounding the display area. Pixels are arranged within the display area to present the display image, while the peripheral area is primarily used for arranging various wiring patterns. This embodiment primarily addresses the design of each hierarchical structure within the corresponding range of the peripheral area within the liquid crystal display module. The pixel design, wiring layout, and fabrication methods for each hierarchical structure within the display area can be designed and manufactured using conventional techniques and are not detailed in this embodiment. Figure 2 A schematic top view of a liquid crystal display module is shown, showing the arrangement of the display area and the peripheral area, and defining a first direction X and a second direction Y. The first direction X mainly corresponds to the horizontal direction in the plane of the liquid crystal display module, and the second direction Y is the vertical direction in the plane perpendicular to the first direction X.

[0033] Figure 3 The schematic diagram of the hierarchical structure of the liquid crystal display module provided in this embodiment is shown, which includes at least a first substrate 10, a liquid crystal layer 20, and a second substrate 30 stacked in sequence. Generally speaking, one of the substrates on both sides of the liquid crystal layer in a liquid crystal display module is usually configured to arrange a thin film transistor array. At the same time, it can also be used to arrange various other wirings including gate lines, wiring for control signals input to the gate drive circuit, or data lines. In this embodiment, this is implemented using the first substrate 10, which is specifically arranged on the side of the liquid crystal display module away from the light-emitting surface. The other substrate is mainly used to arrange color filters. Specifically, it needs to be combined with the design of each pixel in the display area, and corresponding red, green, and blue filters are arranged to filter the light emitted from the liquid crystal layer with the corresponding colors, so that the display module presents a color display image. In this embodiment, this is implemented using the second substrate 30, which is specifically arranged on the side of the liquid crystal display module close to the light-emitting surface. In addition, when actually setting up the color filter substrate, a black matrix BM should be placed between adjacent color filters to prevent light from interfering with adjacent pixels, and the black matrix should extend into the peripheral area to prevent light from overflowing from the boundary between the display area and the peripheral area. Figure 3 The BM layer disposed between the liquid crystal layer 20 and the second substrate 30 refers to the black matrix disposed between the color filters. Its purpose is only to illustrate the corresponding hierarchical structure and does not represent actual hierarchical position, thickness, size and other limitations.

[0034] The gate drive circuit refers to a circuit integrated in the peripheral area for controlling the gates of the TFTs in the display area. It can also be called a GOA circuit (Gate Driven on Array) or a GOA unit. Each GOA unit can be used to drive one or more gate lines to turn on or off the gates connected to the gate lines. In this embodiment, the gate drive circuit is divided into two parts and is respectively prepared on the surfaces of the first substrate 10 and the second substrate 30. The first surface of the first substrate 10 close to the liquid crystal layer 20 (i.e., the liquid crystal layer 20) is the first surface of the first substrate 10. Figure 3 A first number of first gate driving circuits are arranged on the upper surface of the first substrate 10, and all the first gate driving circuits are located within the orthographic projection of the peripheral area on the first surface, and the space occupied by them is Figure 3 Indicated by the shaded portion; correspondingly, on the second surface of the second substrate 30 close to the liquid crystal layer 20 (ie Figure 3 A second number of second gate drive circuits are arranged on the lower surface of the second substrate 30, and all the second gate drive circuits are within the orthographic projection of the peripheral area on the second surface, and the space occupied by them is Figure 3 The first gate drive circuit and the second gate drive circuit have the same size and function, but are prepared on different substrate surfaces. Figure 3 The shaded portion in FIG. 1 is only used to indicate the space occupied by the first gate drive circuit and the second gate drive circuit on their respective substrate surfaces, which are usually circuits or components printed on the substrate surface. Figure 3 The thickness of the shaded area does not refer to the actual thickness of the area.

[0035] Combine Figure 2The top view of the liquid crystal display module shown in the figure shows that in conventional technology, all gate drive circuits are arranged on the substrate where the TFT is located, and are arranged in accordance with their positions corresponding to the gate lines. Generally speaking, the gate drive circuits are evenly distributed within the peripheral area on the left and / or right side of the display module, and occupy a certain amount of space in both the first and second directions. However, the length of the liquid crystal display module in the second direction is limited by the size of the display area or actual needs. Even if the number of gate drive circuits arranged in the second direction is reduced, it will generally not have a significant impact on the border size of the liquid crystal display module. However, if the length in the second direction remains unchanged, the more gate drive circuits there are, the wider the space they occupy in the first direction, which in turn makes it impossible to reduce the width of the peripheral areas on the left and right sides, that is, the purpose of narrow borders cannot be achieved. However, this embodiment uses the substrate where the TFT is located and the substrate where the color filter is located to simultaneously arrange the gate drive circuits, so that the number of gate drive circuits arranged on either side of the substrate of this embodiment is smaller than the number of gate drive circuits arranged on a single-side substrate in the conventional design. Therefore, while the size available for gate drive circuit arrangement in the vertical direction remains unchanged, the width available for gate drive circuit arrangement in the horizontal direction is reduced, that is, Figure 3 The width of the shaded area is less than Figure 1 The width of the shaded portion is reduced, thereby achieving the effect of reducing the width of the peripheral area in the horizontal direction, and ultimately achieving the purpose of reducing the frame of the liquid crystal display module.

[0036] Specifically, a thin film transistor array and a plurality of gate lines extending along a first direction are arranged on the first surface of the first substrate 10. Each gate line is connected to the gates of all thin film transistors in the same row of the thin film transistor array. The plurality of gate lines are arranged sequentially along a second direction to connect and control the gates of each row of thin film transistors in the thin film transistor array. In this embodiment, the thin film transistor array is generally located within the orthographic projection of the display area on the first surface, and at least one end of the gate line is located within the orthographic projection of the peripheral area on the first surface, so that the end of the gate line is connected to the output end of the gate drive circuit. In some embodiments, a single gate line can be driven simultaneously by two gate drive circuits arranged in the left and right peripheral areas to increase the gate drive speed and improve the refresh rate of the display module. Whether the gate line implements single-sided GOA drive or double-sided GOA drive can be designed according to actual needs and is not limited in this embodiment. A color filter is correspondingly provided in the orthographic projection of the display area corresponding to the second surface. Its specific arrangement and color arrangement can be designed according to actual needs and are not described in detail in this embodiment.

[0037] In this embodiment, the first gate drive circuit and the second gate drive circuit corresponding to the first gate drive circuit and the second gate drive circuit are respectively used to drive different gate lines. Specifically, the gate lines include a first number of first gate lines and a second number of second gate lines, each first gate drive circuit is used to drive a first gate line, and each second gate drive circuit is used to drive a second gate line, and there is no overlap or omission between the gate lines driven by different gate drive circuits. When the first gate lines and the second gate lines are actually divided, it is preferred that at least a preset number of second gate lines be set between two adjacent first gate lines so that the first gate lines and the second gate lines are distributed in an alternating interval. Then, when the first gate drive circuit and the second gate drive circuit are set, the longitudinal space in the second direction can be utilized as much as possible to reduce the space occupied in the horizontal direction. In some embodiments, the value of the preset number can be any integer from 1 to 5, and its optimal value is 1. At this time, the values ​​of the first number and the second number can be the same or the difference between the two can be minimized, so that the number of the first gate drive circuit and the second gate drive circuit can be exactly the same or the difference in number can be minimized. In theory, the width occupied by the gate drive circuit in the first direction in this embodiment can be half of the conventional design to achieve the optimal effect of frame reduction.

[0038] Furthermore, for solutions that design gate drive circuits on both substrates, the input and output connections of the gate drive circuits also need to be considered. The first gate drive circuit disposed on the first substrate 10 can directly connect its input and output according to existing designs. However, the second gate drive circuit disposed on the second substrate 30 cannot be directly connected because the second gate lines it actually controls are not disposed at the same level as the second gate drive circuit. This embodiment utilizes a connection area and connector design to achieve signal connectivity between the second gate drive circuit on the second substrate 30 and the first substrate 10.

[0039] Figure 4 A partial schematic diagram of the second surface is shown. Figure 4As shown, a third number of first connection areas 31 and a second number of second connection areas 32 are arranged on the second surface, wherein the first connection areas 31 are mainly used to connect to the input terminals of each second gate drive circuit. The third number can be related to the number of control signals designed on the first substrate 10, and can connect the input terminals of all second gate drive circuits that need to input the same control signal through the leads arranged on the second surface; the second connection areas 32 are mainly used to connect to the output terminals of the second gate drive circuits, and each second gate drive circuit is provided with an independent second connection area 32 to output its own signal, so the number of second connection areas 32 is the same as the second gate drive circuit. The first connection area 31 and the second connection area 32 can specifically be metal conductive areas arranged at different positions on the second surface, such as electrode sheets, and their positions should be in the positive projection of the peripheral area on the second surface. In addition, Figure 4 Two first connection areas 31 are shown, and the second number of second gate drive circuits can be connected to the two first connection areas 31 in sequence and at intervals; at the same time, due to the size limitation of the local image, Figure 4 Only the arrangement of two second connection areas 32 is shown in the figure, and the positions of the remaining second connection areas 32 not shown can be arranged accordingly.

[0040] Cooperate Figure 4 The connection area design shown, Figure 5 Schematic diagram of the first surface is shown. Figure 5 As shown, a third number of first connectors 11 and a second number of second connectors 12 are arranged on the first surface, wherein the first connector 11 is used to connect to the output end of the control signal, and the second connector 12 is used to connect to one end of the second gate line (that is, connected to the end of the second gate line extending into the peripheral area); at the same time, when the first substrate 10 and the second substrate 20 are aligned, it should be ensured that the first connector 11 is in contact with its corresponding first connection area 31 to achieve electrical connection, and the second connector 12 is in contact with its corresponding second connection area 32 to achieve electrical connection, so the number and arrangement positions of the first connectors 11 should correspond to the first connection area 31; that is, the orthographic projection of the first connector 11 on the first surface and the orthographic projection of the first connection area 31 on the first surface at least partially overlap, so that the first connector 11 and the first connection area 31 are electrically connected, and the above-mentioned overlapping portion is the portion where the two are in contact and connected; correspondingly, the orthographic projection of the second connector 12 on the first surface and the orthographic projection of the second connection area 32 on the first surface at least partially overlap, so that the second connector 12 and the second connection area 32 are electrically connected, and the above-mentioned overlapping portion is the portion where the two are in contact and connected.

[0041] It should be noted that the control signal mentioned in this embodiment is usually a clock signal CLK input to the gate driving circuit to instruct the gate driving circuit to output a driving signal, which is generally arranged on one side of the TFT substrate. Figure 5 A total of four clock signals are shown, namely CLK1 to CLK4. The above four clock signals are divided into two groups. The first group is CLK2 and CLK4, which are used to control the first gate drive circuit. The specific connection method can be implemented by referring to the conventional design; the second group is CLK1 and CLK3, which are used to control the second gate drive circuit. Therefore, the third number in this embodiment is 2, and the two clock signals in the same group are connected to different gate drive circuits as needed. In fact, there are also schemes that use six or eight clock signals as control signals to meet different display requirements. The corresponding third number value can be adjusted to 3 or 4. Of course, the third number value can also be determined according to the ratio between the first number and the second number. This is not limited in this embodiment. In addition, Figure 4 and Figure 5 The area marked by the dotted frame is the bonding area after the two substrates are aligned. Figure 5 The first surface presented is used as a reference. Figure 4 After vertically flipping 180°, the positions of the first connecting member 11 and the first connecting area 31 should coincide with each other, and the positions of the second connecting member 12 and the second connecting area 32 should also coincide with each other, so as to indicate the connection status of the two substrates after alignment. Figure 4 and Figure 5 This is for illustration only. Even if one of them is flipped, there may be incomplete correspondence due to drawing errors.

[0042] In some embodiments, corresponding to the design in which the first connection area 31 and the second connection area 32 exist in the form of electrode sheets, the first connector 11 and the second connector 12 can be a connecting foot structure 40, that is, the electrical connection between the electrode sheets is achieved through the design of a support portion with a certain thickness combined with a conductive layer. Figure 6 A cross-sectional schematic diagram of the connecting pin structure 40 is shown, wherein the supporting portion 41 is implemented as a truncated cone structure, which can be specifically prepared using the PS material used for support in the display panel, and its thickness should at least ensure that the upper bottom surface of the truncated cone structure is in contact with its corresponding connection area after the two substrates are aligned, that is, the height of the truncated cone structure can be the vertical distance between the first surface and the second surface; the conductive layer 42 is a conductive material layer covering the upper bottom surface of the truncated cone structure and at least a part of the side surface of the truncated cone structure, such as a conductive glue or a conductive metal layer, wherein the portion covering the upper bottom surface of the truncated cone structure is used to contact the electrode sheet of the connection area, and the portion covering the side wall of the truncated cone structure is mainly used to connect with the control signal output end or the input end of the second gate line arranged on the first surface.

[0043] In actual implementation, the first connection area 31 and the second connection area 32 can also be designed to match the connecting pin structure. For example, a groove structure is designed in the area where the first connection area 31 and the second connection area 32 are located, and the shape of the groove completely matches the shape of the connecting pin structure. The electrode sheets of the first connection area 31 and the second connection area 32 are exposed at the bottom of the groove, so that the connecting pin structure is embedded in the groove structure after matching to form a complete cylinder or rectangular parallelepiped; or a connection area in the form of an electrode sheet is set on the first surface, and a connector with a connecting pin structure is set on the second surface.

[0044] In some embodiments, an encapsulation layer 21 surrounding the liquid crystal layer 20 can also be used to achieve signal communication between the two substrates. In current conventional designs, the encapsulation layer 21 is primarily used to encapsulate the liquid crystal layer 20 and is typically located at the junction of the display area and the peripheral area. When using the encapsulation layer 21 for signal communication between the two substrates, the width of the encapsulation layer 21 can be appropriately widened so that it extends toward the peripheral area and covers the first connection area, the second connection area, the first connector, and the second connector. The encapsulation layer 21 is provided with multiple conductive portions. The conductive portions specifically refer to portions of the encapsulation layer 21 that extend through the encapsulation layer 21 and have conductive properties. These portions are located corresponding to the locations of the first connection area and the first connector, the second connection area, and the second connector, and any two conductive portions are insulated from each other to prevent signal crosstalk. In actual implementation, metal conductive particles can be mixed into the encapsulation layer 21 where the conductive portions are required, so that the insulating encapsulation layer 21 has conductive properties at the locations where the conductive portions are located.

[0045] In this embodiment, the gate drive circuit originally arranged on one side of the substrate in the liquid crystal display module is arranged on both side substrates, so that the space for arranging the gate drive circuit on one side of the substrate remains unchanged in the vertical direction while the horizontal size is reduced, thereby achieving the purpose of reducing the frame of the liquid crystal display module.

[0046] For the functional implementation of the LCD module, refer to Figure 3 A first polarizer POL1 is provided on the side of the first substrate 10 away from the liquid crystal layer 20, and a second polarizer POL2 is provided on the side of the second substrate 10 away from the liquid crystal layer 20. The polarization direction of the first polarizer is parallel to or perpendicular to the polarization direction of the second polarizer. In conjunction with the deflection of the liquid crystal molecules in the liquid crystal layer 20 by the TFT array, the emission of light and the adjustment of the display brightness can be achieved. Figure 3Also shown are the first and second alignment films PI1 and PI2 on either side of the liquid crystal layer 20, which are primarily used to limit the initial deflection angle of the liquid crystal molecules in the liquid crystal layer. Furthermore, the liquid crystal display module should also include a backlight source, a light guide plate, a glass cover, and even a touch screen layer, among other structural elements, which are not described or illustrated in detail in this embodiment.

[0047] The second embodiment of the present disclosure provides an electronic device, which includes at least the liquid crystal display module provided by the first embodiment of the present disclosure, and combined with the double-sided design of the gate drive circuit in the liquid crystal display module, the border of the liquid crystal display module is reduced. Especially for small-sized display devices such as smartphones, smart watches and tablets, the solution of this embodiment can enable the electronic device to present a display screen with a larger proportion, so that users have a better user experience.

[0048] The above describes in detail multiple embodiments of the present disclosure, but the present disclosure is not limited to these specific embodiments. Those skilled in the art can make various variations and modifications to the embodiments based on the concepts of the present disclosure, and these variations and modifications should all fall within the scope of protection claimed by the present disclosure.
