Consumers are no longer only satisfied with the needs of calls for terminal devices, and the demands for display are constantly improving, and the proportion of super-large screens is even Full-screen mobile phones are also increasingly favored by consumers. However, in the design of these mobile phones, the increase of the screen ratio is limited by the traditional top camera, earpiece, ambient light sensor and the like, and in particular, the size of the non-effective display area of the display module. The limitation of the screen makes it impossible to completely eliminate the border of the screen. For example, on a mobile phone using a liquid crystal display (LCD), liquid crystal is injected into the effective display area of the LCD display device to display information for the user of the electronic device; the non-effective display area of the LCD display device is used for setting An integrated circuit (IC) chip for controlling an LCD display device, a related component, and a control circuit.

为了实现更窄的手机边框设计，在现有的采用覆晶薄膜的(Chip On Flex，简称：COF)技术中，IC芯片设置在FPC连接线上而不是LCD显示器件的非有效显示区内，一定程度上减少了IC芯片对非有效显示空间的占用。In order to realize a narrower cell phone frame design, in the existing Chip On Flex (COF) technology, the IC chip is disposed on the FPC connection line instead of the ineffective display area of the LCD display device. To some extent, the IC chip's occupation of non-effective display space is reduced.

但现有技术中，LCD显示器件的非有效显示区的尺寸较大。However, in the prior art, the size of the ineffective display area of the LCD display device is large.

Wherein the position between the CF glass 11 and the effective display area AA of the TFT glass 12 is injected into the liquid crystal for displaying information for the user of the electronic device; the CF glass 11 and the non-effective display area IA of the TFT glass 12 are provided for controlling the effective display. The components and control circuitry of the display device within zone AA are therefore not used for display. Further, at the lower frame of the electronic device shown in FIG. 3A, the length of the CF glass 11 in the direction of the lower frame is shorter than the length of the TFT glass 12 in the direction of the lower frame, so that the TFT glass 12 leaks a step portion toward the direction of the CF glass 11. An integrated circuit (IC) chip 4 for driving the display of the glass substrate is disposed on the step portion of the TFT glass 12 in the direction toward the CF glass 11. Further, the CF glass 11 and the TFT glass 12 have the same length in the direction of the upper frame, the left frame, and the right frame of the electronic device. Further, in the example shown in Fig. 3A, the backlight module 2 slightly protrudes from the structural design of the TFT glass 12 at the first edge of the lower frame, so that the protruding portion TFT glass 12 provides protection against flaws.

当COG结构的LCD显示器件应用在图1所示的电子设备中时，设置在电子设备10的壳体101的前表面上方的IC芯片4需要通过FPC3才能与位于电子设备10的壳体101的前表面下方的主板连接。而IC芯片4通过FPC3才能接收手机主板上的CPU发送的控制信号并根据控制信号调整LCD显示器件的参数。具体的连接结构具体如图4所示，设置在TFT玻璃12远离背光模组3方向的IC芯片4通过在TFT玻璃12远离背光模组3方向上设置的控制电路连接TFT玻璃2上设置的焊盘51。焊盘51与设置在FPC3的第一主体段32上对应数目的焊盘52电耦接。优选地，电耦接方式为导方性导电胶膜(Anisotropic Conductive Film，简称：ACF)连接。FPC3位于第二主体段33的第二端被置于图中整个LCD显示器件下方，与电子设备10内的主板连接。IC芯片4需要依次通过第一主体段32、弯折部31和第二主体段33才能连接电子设备的主板。因此，FPC3需要通过绕过TFT玻璃12和背光模组2下边框的第一边缘最外侧才能与电子设备的主板连接。When the LCD display device of the COG structure is applied in the electronic device shown in FIG. 1, the IC chip 4 disposed above the front surface of the casing 101 of the electronic device 10 needs to pass through the FPC 3 to be in contact with the casing 101 of the electronic device 10. The motherboard connection below the front surface. The IC chip 4 can receive the control signal sent by the CPU on the mobile phone main board through the FPC3 and adjust the parameters of the LCD display device according to the control signal. Specifically, as shown in FIG. 4, the IC chip 4 disposed in the direction away from the backlight module 3 of the TFT glass 12 is connected to the TFT glass 2 by a control circuit disposed in a direction away from the backlight module 3 of the TFT glass 12. Disk 51. The pads 51 are electrically coupled to a corresponding number of pads 52 disposed on the first body segment 32 of the FPC 3. Preferably, the electrical coupling manner is an Anisotropic Conductive Film (ACF) connection. The second end of the FPC 3 at the second body segment 33 is placed under the entire LCD display device in the figure and is connected to the motherboard in the electronic device 10. The IC chip 4 needs to pass through the first body segment 32, the bent portion 31 and the second body segment 33 in order to connect the main board of the electronic device. Therefore, the FPC 3 needs to be connected to the main board of the electronic device by bypassing the outermost side of the first edge of the TFT glass 12 and the lower frame of the backlight module 2.

而在如图3B所示的FPC3弯折后的结构示意图中，FPC3通过绕过TFT玻璃12和背光模组2下边框形成一弯折部31，且弯折部31突出于整个LCD显示器件的在电子设备下边框处的第一边缘的外部。In the schematic diagram of the FPC3 bent as shown in FIG. 3B, the FPC 3 forms a bent portion 31 by bypassing the TFT glass 12 and the lower frame of the backlight module 2, and the bent portion 31 protrudes from the entire LCD display device. On the outside of the first edge at the bottom frame of the electronic device.

如图5A所示，采用覆晶薄膜的(Chip On Flex，简称：COF)技术的电子设备的LCD显示器件包括：CF玻璃11、TFT玻璃12、背光模组2和柔性电路板(Flexible Printed Circuit，简称：FPC)连接线3。其中CF玻璃11和TFT玻璃12的有效显示区AA之间的位置注入液晶，用于为电子设备的用户显示信息；CF玻璃11和TFT玻璃12的非有效显示区IA内设置用于控制有效显示区AA内显示器件的相关组件及控制电路因此不用于显示。用于驱动玻璃基板显示的集成电路(Integrated Circuit，简称IC)芯片4设置在FPC连接线3的第二主体段33上。而IC芯片4需要通过FPC3与位于电子设备壳体的前表面上方的信号线连接，以向LCD显示器件发送控制信号。如图5A所示的电子设备下边框处，CF玻璃11在下边框方向的长度短于TFT玻璃12在下边框方向的长度，使得TFT玻璃12朝向CF玻璃11的方向漏出一个台阶部分。而在台阶部分设置有焊盘51，焊盘51与设置在FPC3的第一主体段32上对应数目的焊盘52电耦接。使得IC芯片4能够通过FPC3接收主板上的CPU发送的控制信号，并通过与焊盘51连接的TFT12上的信号线发送控制信号。As shown in FIG. 5A, an LCD display device of an electronic device using a Chip On Flex (COF) technology includes: CF glass 11, TFT glass 12, backlight module 2, and flexible printed circuit board (Flexible Printed Circuit) , referred to as: FPC) connection line 3. Wherein the position between the CF glass 11 and the effective display area AA of the TFT glass 12 is injected into the liquid crystal for displaying information for the user of the electronic device; the CF glass 11 and the non-effective display area IA of the TFT glass 12 are provided for controlling the effective display. The components and control circuitry of the display device within zone AA are therefore not used for display. An integrated circuit (IC) chip 4 for driving the display of the glass substrate is disposed on the second body segment 33 of the FPC connection line 3. The IC chip 4 needs to be connected to a signal line located above the front surface of the electronic device casing through the FPC 3 to transmit a control signal to the LCD display device. As shown in FIG. 5A, the length of the CF glass 11 in the direction of the lower frame is shorter than the length of the TFT glass 12 in the direction of the lower frame, so that the TFT glass 12 leaks a stepped portion in the direction of the CF glass 11. The pad portion 51 is provided with a pad 51 electrically coupled to a corresponding number of pads 52 provided on the first body segment 32 of the FPC 3. The IC chip 4 is enabled to receive a control signal transmitted from the CPU on the main board through the FPC 3, and to transmit a control signal through a signal line on the TFT 12 connected to the pad 51.

当COF结构的LCD显示器件应用在图1所示的电子设备中时，设置在电子设备10的壳体101的前表面下方的FPC3的第二主体段33上的IC芯片4。具体的连接结构具体如图6所示，设置在FPC3的第二主体段33的IC芯片4最终需要通过第二主体段33、弯折部31和第一主体段32才能连接TFT玻璃12上的信号线，使得FPC3需要通过绕过TFT玻璃12和背光模组2下边框的第一边缘最外侧才能实现IC芯片4与TFT玻璃12上信号线的连接。When the LCD display device of the COF structure is applied in the electronic device shown in FIG. 1, the IC chip 4 on the second body segment 33 of the FPC 3 below the front surface of the casing 101 of the electronic device 10 is disposed. The specific connection structure is specifically as shown in FIG. 6. The IC chip 4 disposed on the second body segment 33 of the FPC 3 finally needs to be connected to the TFT glass 12 through the second body segment 33, the bent portion 31 and the first body segment 32. The signal line is such that the FPC3 needs to connect the signal lines of the IC chip 4 and the TFT glass 12 by bypassing the outermost edges of the first edges of the TFT glass 12 and the lower frame of the backlight module 2.

而在如图5B所示的FPC3弯折后的结构示意图中，FPC3通过绕过TFT玻璃12和背光模组2下边框形成一弯折部31，且弯折部31突出于整个LCD显示器件的在电子设备下边框处的第一边缘的外部。In the schematic diagram of the FPC3 bent as shown in FIG. 5B, the FPC 3 forms a bent portion 31 by bypassing the TFT glass 12 and the lower frame of the backlight module 2, and the bent portion 31 protrudes from the entire LCD display device. On the outside of the first edge at the bottom frame of the electronic device.

综上，采用COG技术的LCD显示器件，FPC的弯折部需要突出于LCD显示器件的背光模组和TFT玻璃设置，造成了LCD显示器件的非有效显示区尺寸较大。COF技术的显示器件虽然将IC芯片设置在FPC的第二主体段，但是FPC的弯折部占用的LCD显示器件的非有效显示区尺寸仍然较大。In summary, the LCD display device using COG technology, the bent portion of the FPC needs to protrude from the backlight module of the LCD display device and the TFT glass setting, resulting in a large size of the non-effective display area of the LCD display device. The display device of the COF technology, although the IC chip is disposed in the second body segment of the FPC, the size of the ineffective display area of the LCD display device occupied by the bent portion of the FPC is still large.

其中，上述实施例一的附图中示出了COG结构的LCD显示器件上，可以如何通过裁剪用于容纳FPC弯折部的缺口来减少LCD显示器件的非有效显示区IA的尺寸。具体地，在实施例一中LCD显示器件的TFT玻璃12和背光模组2在电子设备10的下边框的第一边缘处设置用于容纳FPC3的弯折部的缺口。使得FPC3弯折后弯折部的最突出处不会超出TFT玻璃12和背光模组2在电子设备10的下边框的第一边缘处的最外侧。其中优选地，为了减少对TFT玻璃上IC芯片和其他控制元件的信号线的影响，用于容纳FPC3的弯折部的缺口设置在电子设备10的下边框处第一边缘的两侧。同时，由于在TFT玻璃12上设置了缺口，需要根据设置缺口后的TFT玻璃12的形状，对TFT玻璃12上的信号线分布、走向以及连接FPC的焊盘52进行调整。并根据设置缺口后TFT玻璃12的形状调整FPC连接线第一端的焊盘51的形状与位置，使得TFT玻璃12上设置的焊盘51与设置在FPC3的第一主体段32上对应位置及数目的焊盘52电耦接。Wherein, in the drawing of the first embodiment, it is shown how the size of the non-effective display area IA of the LCD display device can be reduced by cutting the notch for accommodating the FPC bent portion on the LCD display device of the COG structure. Specifically, in the first embodiment, the TFT glass 12 and the backlight module 2 of the LCD display device are provided with a notch for accommodating the bent portion of the FPC 3 at the first edge of the lower frame of the electronic device 10. The most prominent portion of the bent portion after the FPC 3 is bent does not exceed the outermost side of the TFT glass 12 and the backlight module 2 at the first edge of the lower frame of the electronic device 10. Preferably, in order to reduce the influence on the signal lines of the IC chip and other control elements on the TFT glass, the notches for accommodating the bent portions of the FPC 3 are disposed on both sides of the first edge at the lower frame of the electronic device 10. At the same time, since the TFT glass 12 is provided with a notch, it is necessary to adjust the signal line distribution and the direction on the TFT glass 12 and the pad 52 to which the FPC is connected in accordance with the shape of the TFT glass 12 after the notch is provided. And adjusting the shape and position of the pad 51 at the first end of the FPC connection line according to the shape of the TFT glass 12 after the gap is formed, so that the pad 51 disposed on the TFT glass 12 and the corresponding position on the first body segment 32 of the FPC 3 are The number of pads 52 is electrically coupled.

如图7B所示，在本实施例中，FPC3可以设置多个弯折部。使得FPC3在弯折后形成第一弯折部311和第二弯折部312。FPC3设置多个弯折部后，而如图8所示，FPC3的第一主体段32能够通过第一弯折部311和第二弯折部312连接第二主体段33。需要说明的是，本示例中包括两个弯折部，而具体实现时可以根据工程需要设置任意数目的弯折部，均在本实施例保护范围之内。As shown in FIG. 7B, in the present embodiment, the FPC 3 can be provided with a plurality of bent portions. The FPC 3 is caused to form the first bent portion 311 and the second bent portion 312 after being bent. After the FPC 3 is provided with a plurality of bent portions, as shown in FIG. 8, the first body portion 32 of the FPC 3 can be connected to the second body portion 33 through the first bent portion 311 and the second bent portion 312. It should be noted that, in this example, two bending portions are included, and in the specific implementation, any number of bending portions can be set according to engineering requirements, which are all within the protection range of the embodiment.

为了容纳FPC3弯折后的第一弯折部311和第二弯折部312，如图7A所示，TFT玻璃12和背光模组2位于电子设备10的下边框的第一边缘处的左右两侧各设置一裁剪出的缺口，且TFT玻璃12和背光模组2裁剪的形状相同，使得电子设备10的下边框的第一边缘处形成图7A中所示的第一缺口71和第二缺口72。其中，第一缺口71和第二缺口72向上裁剪的距离分别匹配第一弯折部311和第二弯折部312的弯折尺寸，第一缺口71和第二缺口72两侧向手机轴线方向裁剪的距离分别匹配第一弯折部311和第二弯折部的宽度。使得将FPC3的第一弯折部311和第二弯折部312能够完全容纳在第一缺口71和第二缺口72内，从而减小了LCD显示器件的非有效显示区IA的尺寸。其中，缺口的结构可以通过图8的剖面图中示出，图8中A-A方向的剖面图仅能示出第一缺口71。TFT玻璃12的裁剪部分为图中标号711处，背光模组2的裁剪位置为图中标号712处，并由两处裁剪出的空间形成第一缺口71，用于容纳位于该侧FPC的第一弯折部311。In order to accommodate the first bent portion 311 and the second bent portion 312 after the FPC 3 is bent, as shown in FIG. 7A, the TFT glass 12 and the backlight module 2 are located at the left and right edges of the lower frame of the electronic device 10 A cut-out notch is provided on each side, and the TFT glass 12 and the backlight module 2 are cut in the same shape, so that the first notch 71 and the second notch shown in FIG. 7A are formed at the first edge of the lower frame of the electronic device 10. 72. The distance between the first notch 71 and the second notch 72 is matched to the bending size of the first bending portion 311 and the second bending portion 312, respectively. The first notch 71 and the second notch 72 are directed to the axis of the mobile phone. The cut distances match the widths of the first bent portion 311 and the second bent portion, respectively. The first bent portion 311 and the second bent portion 312 of the FPC 3 can be completely accommodated in the first notch 71 and the second notch 72, thereby reducing the size of the ineffective display area IA of the LCD display device. The structure of the notch can be shown in the cross-sectional view of FIG. 8, and the cross-sectional view in the A-A direction of FIG. 8 can only show the first notch 71. The cut portion of the TFT glass 12 is at the reference numeral 711 in the figure, and the cutting position of the backlight module 2 is at the reference numeral 712 in the figure, and the space cut by the two places forms a first notch 71 for accommodating the first FPC on the side. A bent portion 311.

由于在TFT玻璃12上设置了缺口，需要调整TFT玻璃12上远离背光模组2一侧原有的焊盘52的分布。同时，设置在FPC3第一端的焊盘51需要与TFT玻璃12电耦接，因此第一端的焊盘51也需要进行相应地位置调整设置。例如图7A中所示，IC芯片4设置在TFT玻璃12位于电子设备10下方的非有效显示区上。TFT玻璃12上的焊盘52设置在IC芯片两侧的非有效显示区上。优选地,焊盘52沿TFT玻璃12上缺口的边缘处设置，以减少对原有信号线的走线以及有效显示区AA的影响。本实施例中焊盘TFT玻璃12上焊盘的设置，与图3A中焊盘设置在IC芯片4下方的相比，焊盘52的位置更靠近IC芯片侧面的上方且结构更为紧凑。能够通过焊盘52位置的调整设置缩短COG结构中TFT玻璃12远离玻璃模组一侧设置的焊盘52对非有效显示区IA的占用。Since the notch is provided on the TFT glass 12, it is necessary to adjust the distribution of the original pads 52 on the side of the TFT glass 12 away from the backlight module 2. At the same time, the pad 51 disposed at the first end of the FPC 3 needs to be electrically coupled to the TFT glass 12, so the pad 51 of the first end also needs to be adjusted accordingly. For example, as shown in FIG. 7A, the IC chip 4 is disposed on the ineffective display area of the TFT glass 12 under the electronic device 10. The pads 52 on the TFT glass 12 are disposed on the non-effective display areas on both sides of the IC chip. Preferably, the pads 52 are disposed along the edges of the notches on the TFT glass 12 to reduce the effects on the traces of the original signal lines and the effective display area AA. In the present embodiment, the pad on the pad TFT glass 12 is disposed closer to the side of the IC chip than the pad of FIG. 3A disposed under the IC chip 4, and the structure is more compact. The adjustment of the position of the pad 52 can shorten the occupation of the non-effective display area IA by the pad 52 disposed on the side of the TFT glass 12 away from the glass module in the COG structure.

如图7A为FPC3处于非弯折状态时的结构示意图，此时FPC3的第一端的N个焊盘51与设置在TFT玻璃12上的N个焊盘52电耦接。此时FPC3没有经过弯折，平行于玻璃基板1和背光模组2。7A is a schematic structural view of the FPC 3 in a non-bending state. At this time, the N pads 51 of the first end of the FPC 3 are electrically coupled to the N pads 52 disposed on the TFT glass 12. At this time, the FPC 3 is not bent, and is parallel to the glass substrate 1 and the backlight module 2.

如图7B和图8所示，此时FPC3的进行弯折后得到第一弯折部311和第二弯折部312，弯折部将两侧的FPC3分为第一主体段32和第二主体段33。第一主体段32设置在玻璃基板1远离背光模组2的一侧，第二主体段33设置在背光模组2远离玻璃基板的一侧。当FPC3处于弯折状态时，FPC3的第一弯折部311和第二弯折部312被分别容纳在LCD显示器件的TFT玻璃12和背光模组2设置的第一缺口71和第二缺口72中，弯折部的最突出部位也不会超出LCD显示器件的第一边缘的下边框处，从而有效减小了LCD显示器件的非有效显示区IA的尺寸。As shown in FIG. 7B and FIG. 8 , at this time, the FPC 3 is bent to obtain a first bent portion 311 and a second bent portion 312 , and the bent portion divides the FPC 3 on both sides into a first body segment 32 and a second portion. Body segment 33. The first body segment 32 is disposed on a side of the glass substrate 1 away from the backlight module 2, and the second body segment 33 is disposed on a side of the backlight module 2 away from the glass substrate. When the FPC 3 is in a bent state, the first bent portion 311 and the second bent portion 312 of the FPC 3 are respectively accommodated in the TFT glass 12 of the LCD display device and the first notch 71 and the second notch 72 provided in the backlight module 2, respectively. The most prominent portion of the bent portion does not extend beyond the lower edge of the first edge of the LCD display device, thereby effectively reducing the size of the non-effective display area IA of the LCD display device.

此外，图9A-图9D为本申请LCD显示器件实施例一中不同缺口设置方式的结构示意图。示出了电子设备在第一边缘处设置用于容纳FPC弯折部的缺口时，可能出现的四种实施例。缺口的位置可设置在第一边缘处的单侧或两侧。焊盘的数量及位置可根据实际需要使用的信号线数目进行设置。FPC的弯折部数目、第一主体段和第二主体段的形状可根据TFT玻璃和背光模组的背光结构进行设置，以避免焊盘及FPC的第一主体段对玻璃基板和背光模组正常显示的影响。9A-9D are schematic structural diagrams of different gap setting modes in the first embodiment of the LCD display device of the present application. Four embodiments that may occur when the electronic device is provided with a notch for receiving the FPC bend at the first edge are shown. The position of the notch can be set on one side or both sides at the first edge. The number and position of the pads can be set according to the number of signal lines that are actually needed. The number of the bent portions of the FPC, the shape of the first body segment and the second body segment may be set according to the backlight structure of the TFT glass and the backlight module to avoid the first body segment of the pad and the FPC to the glass substrate and the backlight module The effect of normal display.

可选地，在本申请上述的实施例一中，IC芯片4的管脚顺序和位置可以根据TFT玻璃12上的信号线的走线需求进行调整，使得TFT玻璃12上的走线能够更为直接且有效地连接IC芯片4的管脚。Optionally, in the first embodiment of the present application, the order and position of the pins of the IC chip 4 can be adjusted according to the routing requirements of the signal lines on the TFT glass 12, so that the traces on the TFT glass 12 can be further The pins of the IC chip 4 are directly and efficiently connected.

综上，在上述实施例一所提供的LCD显示器件中，在玻璃基板和背光模组的第一边缘处设置用于容纳FPC弯折部的缺口，使得FPC弯折部的最突出部位能够限制在背光模组和玻璃基板的第一边缘之内，从而使得FPC弯折部能够容纳在缺口中而不突出电子设备的第一边缘，进而减小了LCD显示器件非有效显示区IA的尺寸。In summary, in the LCD display device provided in the first embodiment, a notch for accommodating the FPC bent portion is disposed at the first edge of the glass substrate and the backlight module, so that the most prominent portion of the FPC bent portion can be limited. Within the first edge of the backlight module and the glass substrate, the FPC bent portion can be received in the notch without protruding the first edge of the electronic device, thereby reducing the size of the non-effective display area IA of the LCD display device.

其中，实施例二在实施例一的基础上示出了，可以如何通过在TFT玻璃上设置导电过孔将TFT玻璃上的焊盘设置在靠近背光模组一侧，来进一步减少LCD显示器件的非有效显示区尺寸。具体地，本申请实施例二在上述实施例一的基础上，还包括：N个导电过孔8。The second embodiment shows, on the basis of the first embodiment, how to further reduce the LCD display device by disposing the pads on the TFT glass on the side of the backlight module by providing conductive vias on the TFT glass. Non-effective display area size. Specifically, the second embodiment of the present application further includes: N conductive vias 8 on the basis of the foregoing first embodiment.

由于上述实施例中，TFT玻璃12远离背光模组2一侧设置的IC芯片4及其他控制元件,IC芯片4及其他控制元件的信号线通过FPC3连接位于背光模组2远离TFT玻璃12一侧的主板。而IC芯片4及其他控制元件的信号线需要通过TFT玻璃12上设置的焊盘52连接FPC3的第一端设置的对应的焊盘51才能连接FPC3。但是在TFT玻璃上设置的焊盘52占用了较大的LCD显示器件非有效显示区的尺寸。In the above embodiment, the TFT glass 12 is away from the IC chip 4 and other control components disposed on the side of the backlight module 2, and the signal lines of the IC chip 4 and other control components are connected to the backlight module 2 away from the TFT glass 12 through the FPC3. Motherboard. The signal lines of the IC chip 4 and other control elements need to be connected to the corresponding pads 51 provided at the first end of the FPC 3 through the pads 52 provided on the TFT glass 12 to be connected to the FPC 3.
