Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the embodiments of the present application, the terms "first", "second", "third", "fourth", and the like are used for distinguishing the same or similar items with substantially the same functions and actions, and are used only for clearly describing technical solutions of the embodiments of the present application, and are not understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features.
In the embodiments of the present application, "a plurality" means two or more, and "at least one" means one or more, unless specifically defined otherwise.
In the embodiments of the present application, the terms "upper", "lower", and the like indicate orientations or positional relationships based on orientations or positional relationships shown in the drawings, and are only for convenience of describing the present application and simplifying the description, but do not indicate or imply that the referred devices or elements must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application.
The embodiment of the present application provides a display device, which may be a mobile phone, a notebook computer, an Ultra Mobile Personal Computer (UMPC), a netbook, a Personal Digital Assistant (PDA), an intelligent wearable device, a virtual reality device, or a mobile computing device, and other devices having a display screen. For convenience of description, the display device is an intelligent wearable device as an example for explanation.
The display device comprises a display module for displaying images, and can comprise one or more of a processor, a memory, a mainboard, a communication module and a power supply module according to the requirements of application scenes in the practical application process. When the display device simultaneously comprises the display module, the processor, the memory, the mainboard, the communication module and the power supply module, the mainboard is used for carrying and electrically connecting the modules, and the processor processes information received by the communication module according to an instruction stored by the memory and controls the display module to display a corresponding image under the driving of electric energy provided by the power supply module during working.
The display module includes a display panel 100 and a flexible circuit board 200. The flexible circuit board 200 is used to electrically connect the display panel 100 with a module in the display device. For example, when the display device includes a main board, one end of the flexible circuit board 200 is electrically connected to the display panel 100, and the other end of the flexible circuit board 200 is electrically connected to the main board, so that an electrical signal of the main board is transmitted to the display panel 100 through the flexible circuit board 200.
The Flexible Circuit board 200 may be an FPC (Flexible Printed Circuit) or a chip on Film (CoF for short), and the structure of the Flexible Circuit board 200 is not limited in the present application as long as the display panel 100 and the external module can be electrically connected and can be bent.
The display panel 100 may be an LCD display panel, an LED display panel, an OLED display panel, or an AMOLED (Active-matrix organic light-emitting diode) display panel. The AMOLED display panel has the advantages of flexibility and flexibility, market share is higher and higher, and the AMOLED display panel is widely applied to intelligent wearable equipment.
The display panel 100 may include a display area for displaying an image and a bonding area for implementing an electrical connection with the flexible circuit board 200. To improve the screen ratio of the display device, the binding region may be located at the periphery of the display region.
The bonding region is provided with a plurality of first bonding terminals 110 at intervals, the first bonding terminals 110 are electrically connected to circuits inside the display panel 100, for example, the first bonding terminals 110 are electrically connected to data lines of the display panel 100.
The plurality of first binding terminals 110 may be arranged at intervals along a first direction parallel to the light emitting surface of the display panel 100, that is, the plurality of first binding terminals 110 are arranged in a row or a column. Of course, the plurality of first binding terminals 110 may be arranged in one row or one column after being spaced, or may be arranged in two rows or two columns, which is not limited in the present application.
In practical applications, in order to reduce the area of the non-display region at the edge of the display panel 100, the first direction may be parallel to the edge of the display region. Compared with the first direction perpendicular to the edge of the display area, the first direction is parallel to the edge of the display area, so that the area of the non-display area can be reduced, and the screen occupation ratio is improved.
The flexible circuit board 200 is provided with a plurality of second binding terminals 210 at intervals. The pitch between the first binding terminals 110 may be the same as the pitch between the second binding terminals 210, so that the plurality of first binding terminals 110 and the plurality of second binding terminals 210 correspond one to one.
The first binding terminal 110 and the second binding terminal 210 are electrically connected to achieve electrical connection of the display panel 100 and the flexible circuit board 200.
The first binding terminal 110 and the second binding terminal 210 are electrically connected to form a binding terminal pair, the first binding terminals 110 and the second binding terminals 210 form a plurality of binding terminal pairs, and the heights of the binding terminal pairs may be the same. The height of each binding terminal is the same so that the flexible circuit board 200 after binding is more flat.
Wherein the first binding terminal 110 and the second binding terminal 210 may be electrically connected through a binding process. An anisotropic conductive adhesive layer 300 is disposed between the first binding terminal 110 and the second binding terminal 210, and the first binding terminal 110 and the second binding terminal 210 are electrically connected through conductive particles inside the anisotropic conductive adhesive layer 300, that is, the anisotropic conductive adhesive layer 300 conducts electricity in a direction perpendicular to the light emitting surface of the display panel 100.
In the binding process, when the cleanness degree of the binding environment is not enough, conductive foreign matters drop easily between the first binding terminals 110, between the second binding terminals 210, and between the first binding terminals 110 and the second binding terminals 210, and the conductive foreign matters are communicated with the adjacent binding terminal pairs, so that the adjacent binding terminal pairs are in short circuit, and the display device is abnormal in display.
Fig. 1 is a first schematic view of bonding in the related art, and fig. 2 is a second schematic view of bonding in the related art, in which the conductive adhesive layer is not shown. As shown in fig. 1 and 2, a first foreign object 1 is located on one binding terminal pair, a second foreign object 2 is located on another adjacent binding terminal pair, and the first foreign object 1 and the second foreign object 2 are in contact with each other, so that the two adjacent binding terminal pairs are short-circuited, which causes an abnormal display of the display device.
With continued reference to fig. 2, the third object 3 is located between two adjacent first binding terminals 110, shorting the two adjacent first binding terminals 110, causing the display apparatus to display an abnormality.
In order to achieve better display effect, the requirement for resolution of the display screen is also higher and higher. And the higher the resolution, the more the number of pixels of the display screen, and accordingly the more the number of data lines for controlling the light emission intensity of the pixels, the more the number of first binding terminals 110 connected to the data lines.
However, the space for accommodating the first binding terminal 110 is limited, especially in a display device with a small volume such as a smart wearable device or a display device with a high screen space ratio. A greater number of first binding terminals 110 are arranged in a limited space, so that the distance between adjacent first binding terminals 110 is reduced, and the risk of short circuit between adjacent first binding terminals 110 is further increased.
In view of this, in the embodiment of the present application, at least one of the plurality of first binding terminals 110 and the adjacent first binding terminal 110 are configured to be different, so as to increase the distance between the adjacent first binding terminals 110, thereby reducing the risk of short circuit of the adjacent first binding terminals 110.
At least one of the plurality of first binding terminals 110 may be different in height from the adjacent first binding terminals 110. The height is a dimension perpendicular to the light emitting surface of the display panel 100.
Fig. 3 is a schematic diagram of a display module bound according to an embodiment of the present application. As shown in fig. 3, five first binding terminals 110 are arranged in the binding region, and are numbered as a, b, c, d, and e in the left-to-right direction in the figure. Wherein the height of c in the middle is higher than the heights of b and d adjacent to the c, so that the height difference is generated between the top surface of c and the top surface of d. When the first foreign matter 1 is located on the top surface of c and the second foreign matter 2 is located on the top surface of d, the first foreign matter 1 and the second foreign matter 2 do not contact due to the height difference, and thus e and d are not shorted.
Fig. 4 is a schematic diagram of a display module bound according to an embodiment of the present application. As shown in fig. 4, five first binding terminals 110 are arranged in the binding region, and are numbered as a, b, c, d, and e in the left-to-right direction in the figure. Wherein the height of c in the middle is higher than the height of b and d adjacent to the c, so that the c and the d have a height difference. When the left end of the third object 3 is connected with e, the right end of the third object 3 is connected with the conductive adhesive layer on d. Since the conductive adhesive layer is the anisotropic conductive adhesive layer 300, the conductive adhesive layer conducts electricity in a direction perpendicular to the light emitting surface of the display panel 100, that is, in the vertical direction of the figure, and does not conduct electricity in the horizontal direction. Therefore, even if the third object 3 is connected to the conductive paste layer, the third object 3 cannot short-circuit c and d, thereby reducing the probability that the display device displays an abnormality.
That is, when the first binding terminal 110 is different in height from the adjacent first binding terminal 110, a height difference is generated between the top surface of the first binding terminal 110 and the top surface of the adjacent first binding terminal 110, so that a height difference is generated between a foreign object falling from the top surface of the first binding terminal 110 and a foreign object falling from the top surface of the adjacent first binding terminal 110, and the two foreign objects cannot contact due to the height difference, thereby preventing a short circuit between the adjacent two first binding terminals 110.
In addition, since a height difference is generated between the top surface of the first binding terminal 110 and the top surface of the adjacent first binding terminal 110, a conductive portion of a side edge of the first binding terminal 110 or the second binding terminal 210 along a direction parallel to the light emitting surface of the display panel 100 corresponds to the anisotropic conductive adhesive layer 300 between the first binding terminal 110 and the second binding terminal 210, so that a foreign object can be prevented from short-circuiting the adjacent two first binding terminals 110.
The height difference between two adjacent first binding terminals 110 can be flexibly set according to practical application. Illustratively, the determination may be based on statistics of the size of the foreign object in the binding environment. For example, the height difference between two adjacent first binding terminals 110 is greater than the maximum dimension of the foreign object along the direction perpendicular to the light emitting surface of the display panel 100, or greater than the average dimension of the foreign object along the direction perpendicular to the light emitting surface of the display panel 100.
It is understood that the same effect can be obtained when the height of c is lower than the height of the adjacent first binding terminal 110, and a description thereof will not be repeated.
In practical application, the heights of a, b and c may be the same, and the heights of c and d may be the same. The number of the first binding terminals 110 can also be flexibly set according to actual needs. So long as the height of one of the first ends is made different from the height of the adjacent first terminal.
The number of the first binding terminals 110 different in height from the adjacent first binding terminals 110 may also be two, three, four, etc., and the larger the number, the lower the probability of the display device displaying an abnormality due to a short of the binding terminals.
Any one of the first binding terminals 110 may have a height different from that of the adjacent first binding terminals 110. This can reduce the risk of shorting any one first binding terminal 110 to the adjacent first binding terminal 110, thereby reducing the risk of display abnormality of the display device.
Here, when the heights of any one first binding terminal 110 and the adjacent first binding terminal 110 are different, there may be two cases.
First case
The heights of the first binding terminals 110 are different from each other. When the heights of the first binding terminals 110 are different from each other, the heights of the adjacent first binding terminals 110 are different regardless of the arrangement of the first binding terminals 110. The risk of short between adjacent two first binding terminals 110 may be reduced when the heights of adjacent first binding terminals 110 are not the same.
In addition, since the heights of the first binding terminals 110 are different from each other, the binding terminals can play a fool-proof role, and the first binding terminals 110 and the second binding terminals 210 are prevented from being dislocated.
For example, the height of the second binding terminal 210 is determined according to the height of the first binding terminal 110, so that the heights of the respective binding terminal pairs formed after binding are uniform, thereby making the bound flexible circuit board 200 flat. That is, the first binding terminal 110 having a higher height corresponds to the second binding terminal 210 having a lower height, and the first binding terminal 110 having a lower height corresponds to the second binding end having a higher height. When the corresponding positions of the first binding terminal 110 and the second binding terminal 210 are misaligned in the binding process, that is, the higher first binding terminal 110 corresponds to the higher second binding terminal 210, and the lower first binding terminal 110 corresponds to the lower second binding terminal 210, the flexible circuit board 200 may be uneven, so that the positional relationship between the first binding terminal 110 and the second binding terminal 210 may be adjusted.
When the heights of the respective first binding terminals 110 are different, the plurality of first binding terminals 110 may be arranged in various ways.
The method I comprises the following steps: in the first direction, the height of the first binding terminal 110 gradually changes.
Wherein, the gradual height change means that the height gradually increases or gradually decreases.
Fig. 5 is a schematic diagram of an arrangement of the first binding terminal 110 in the embodiment of the present application. Illustratively, as shown in fig. 5, the height of the first binding terminal 110 gradually increases in a direction from left to right as viewed in the drawing. Of course, the height of the first binding terminal 110 may also be gradually reduced in the left-to-right direction as illustrated.
Here, the height difference between two adjacent first binding terminals 110 may be the same or different.
The height of the first binding terminals 110 is gradually changed in the first direction such that the top surface of each first binding terminal 110 is substantially on an inclined plane, which facilitates the application of the anisotropic conductive adhesive during the binding process. For example, a layer of the anisotropic conductive adhesive layer 300 may be coated along the inclined plane formed on the top surface of each first binding terminal 110, or the prepared anisotropic conductive adhesive layer 300 may be placed on the inclined plane formed on the top surface of each first binding terminal 110.
The second method comprises the following steps: the height of the first binding terminal 110 is gradually changed from the middle to both sides in the first direction.
Wherein, the gradual height change means that the height gradually increases or gradually decreases.
Fig. 6 is a schematic diagram of an arrangement of the first binding terminal 110 in the embodiment of the present application. Illustratively, as shown in fig. 6, the height of the first binding terminal 110 located at the middle position is the highest, and the height of the first binding terminal 110 gradually decreases from the middle to both sides. Of course, the height of the first binding terminal 110 located in the middle may be the lowest, and the height of the first binding terminal 110 gradually increases from the middle to both sides.
Along the first direction, the height of the first binding terminals 110 from the middle to the two sides is gradually changed, so that the top surfaces of the first binding terminals 110 form two inclined planes with a certain included angle, and the anisotropic conductive adhesive is more conveniently coated in the binding process. For example, a layer of the anisotropic conductive adhesive layer 300 may be coated along two inclined planes formed on the top surfaces of the respective first binding terminals 110, or the prepared anisotropic conductive adhesive layer 300 may be placed on the two inclined planes formed on the top surfaces of the respective first binding terminals 110.
Second case
The plurality of first binding terminals 110 include third binding terminals and fourth binding terminals, the third binding terminals having a height greater than that of the fourth binding terminals, and the third binding terminals and the fourth binding terminals are alternately disposed.
The height of the third binding terminal is larger than that of the fourth binding terminal, and the third binding terminal and the fourth binding terminal are arranged in a staggered mode. That is, the first binding terminals 110 are staggered in a high-to-low manner. When the first binding terminals 110 are arranged in a staggered manner, the height difference between the highest first binding terminal 110 and the lowest first binding terminal 110 is reduced while the height difference exists between the two adjacent first binding terminals 110, so that the manufacturing difficulty of the first binding terminals 110 is reduced.
Illustratively, the height of the third binding terminal is within a first height range, the height of the fourth binding terminal is within a second height range, and a minimum value of the first height range is greater than a maximum value of the second height range, so that the height of the third binding terminal is greater than the height of the fourth binding terminal.
Further, the first height range and the second height range may also partially overlap, that is, a part of the third binding terminal may have a height smaller than that of the fourth binding terminal. At this time, the third binding terminal having a smaller height may be disposed adjacent to the fourth binding terminal having a smaller height, and the third binding terminal having a larger height may be disposed adjacent to the fourth binding terminal having a larger height.
Further, the heights of the third binding terminals may be the same, and the heights of the fourth binding terminals may be the same. Such that the plurality of first binding terminals 110 include only the first binding terminals 110 of two heights, so that the preparation of the first binding terminals 110 is simpler.
Fig. 7 is a schematic diagram of an arrangement manner of the first binding terminal 110 and the second binding terminal 210 according to the embodiment of the present application, and fig. 8 is a schematic diagram of the first binding terminal 110 and the second binding terminal 210 according to the embodiment of the present application when binding. For example, as shown in fig. 7 and 8, the first binding terminals 110 are arranged in a staggered manner of one high, one low, and after binding, the first foreign object 1 and the second foreign object 2 can be prevented from being turned on, and the third foreign object 3 can be prevented from short-circuiting the adjacent two first binding terminals 110.
In the case shown in fig. 1 to 8, the first binding terminal 110 has a rectangular cross section. In practical applications, as shown in fig. 9, the cross section of the first binding terminal 110 may be trapezoidal. When the first binding terminal 110 and the second binding terminal 210 are both trapezoidal in cross section, the modified structure of the first binding terminal 110 and the second binding terminal 210 after binding is as shown in fig. 10.
Of course, the cross section of the first binding terminal 110 may also be square or other shapes, which is not limited in this application.
In addition, the adjacent first binding terminals 110 have different structures, and may have different heights: the sizes of the adjacent first binding terminals 110 in the first direction are different, so that the distance between the two adjacent first binding terminals 110 can be increased, and the risk of short circuit between the two adjacent first binding terminals 110 is reduced.
In the embodiment of the present application, the adjacent first binding terminals 110 may have different heights, different sizes along the first direction, or different heights and different sizes along the first direction.
The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
