Detailed ways

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. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. The embodiments in this application can be appropriately combined.

As shown in FIG. 1 , an embodiment of the present application provides an electronic device 100 . The electronic device 100 has the feature of a relatively high screen ratio. The electronic device 100 may be a mobile phone, a tablet computer, a notebook computer, a smart watch, or other devices. The embodiments of the present application take a mobile phone as an example for illustration. In order to achieve a higher screen ratio for devices such as mobile phones, it is necessary to solve the problem of setting the receiver, front camera, etc.

In a method for increasing the screen ratio of the electronic device 100 , the screen ratio of the electronic device 100 is increased by hiding the electronic device 401 in the display screen of the electronic device 100 .

In other words, the electronic device 100 provided by the embodiment of the present application has a display screen and an electronic device 401 , the display screen is provided with a blind hole 40 , and part or all of the electronic device 401 is hidden in the blind hole 40 of the display screen. The electronic device 401 includes but is not limited to a receiver, a front camera, a microphone, a fingerprint recognition module, a face recognition module, an ambient light sensor, a distance sensor, an antenna module, an iris recognition module, and the like.

Specifically, hiding part or all of the electronic device 401 in the display screen means opening a blind hole 40 inside the display screen, the display screen has a display area 103 and a non-display area 104, and the electronic device 401 is arranged in the display area 103 of the display screen, And it is located in the blind hole 40 of the display screen. Compared with the manner in which the electronic device 401 is arranged on the non-display area 104 , the proportion of the display area 103 of the display screen can be increased.

The embodiment of the present application uses the hidden front camera as an example for description. For the water drop screen, Liu Haiping and blind hole screen, the front camera is hidden in the display screen. In the electronic device 100 of this type, since holes are formed in the display screen, there will be gaps around the holes, which are prone to light leakage. Dispensing and sealing around the hole of the display screen after the hole is opened to ensure the shooting effect of the front camera is one of the methods to solve the light leakage of the display screen of this type of electronic device 100. Connection is reliable. However, if the display screen after the dispensing process is directly mass-produced, the glue in the dispensing process may interfere with the front camera to be installed, and the yield of the display screen after mass production cannot be guaranteed.

To this end, the present application provides a dispensing control method, which can detect whether the dispensing process is qualified or not, so as to avoid multiple rework or waste of resources caused by the unqualified display screen entering the subsequent process. The display module and the electronic device 100 controlled by the dispensing control method provided by the present application do not interfere with the electronic device 401, and the yield rate is high. The glue dispensing management and control method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 2 , FIG. 2 is a schematic flowchart of the dispensing management and control method provided by the first embodiment of the present application. The dispensing control method includes at least the following steps:

110: Dispensing glue at the dispensing site in the blind hole of the substrate to form a colloid.

Please refer to FIG. 3 and FIG. 4 , the present application takes a liquid crystal display screen as an example for description, and will not be described in detail in the following. The liquid crystal display screen includes at least a glass cover plate, a liquid crystal substrate 20 , a backlight module 10 and a fixing bracket arranged in sequence from top to bottom. The liquid crystal substrate 20 includes a color filter substrate, a liquid crystal and a thin film transistor array substrate that are stacked in sequence. The substrate, on the other hand, represents a multi-layered component in a liquid crystal display or represents the entire display.

The blind holes 40 of the substrate can be provided in one or more layers of the liquid crystal display. For example, through holes are opened in both the liquid crystal substrate 20 and the backlight module. For the entire liquid crystal display screen, the opened through holes are blind holes 40 . In this method, the light is injected into the front camera through the glass cover, so that the front camera can realize the shooting function. In another embodiment, a through hole can also be opened in the backlight module 10, so that light is injected into the front camera through the glass cover plate and the liquid crystal substrate 20, so that the front camera can realize the shooting function. Of course, in other embodiments, blind holes 40 may also be formed in the glass cover layer of the liquid crystal display, the liquid crystal substrate 20, the backlight module 10 and the fixed layer. It can be understood that the glass cover layer of the liquid crystal display is not completely through.

The dispensing positions 50 corresponding to different opening methods are different. For example, when opening holes in the liquid crystal substrate 20 and the backlight module 10 of the liquid crystal display screen, the gap between the glass cover layer and the liquid crystal substrate 20 may cause light leakage and backlight phenomenon. Therefore, it is necessary to perform glue dispensing and sealing between the glass cover layer and the liquid crystal substrate 20 . At this time, the glue dispensing position 50 represents the connection between the glass cover layer and the inner wall of the hole. In another embodiment, when the backlight module 10 of the liquid crystal display screen has holes, the blind holes 40 penetrate through the backlight module 10 . The gap between the liquid crystal substrate 20 and the backlight module 10 causes light leakage and polarization when light enters the front camera, so it is necessary to seal the liquid crystal substrate 20 and the backlight module 10 . At this time, the glue dispensing position 50 is the connection between the liquid crystal substrate 20 and the inner wall of the hole.

It can be understood that when the glue dispensing positions 50 are different, the positions of the formed gel are different. It can be understood that when the glue dispensing position 50 is located at the connection between the glass cover plate layer and the inner wall of the hole, the glue formed during the dispensing process is located between the glass cover plate and the liquid crystal substrate 20 . When the glue dispensing position 50 is located at the connection between the liquid crystal substrate 20 and the inner wall of the hole, the glue formed during the dispensing process is located between the liquid crystal substrate 20 and the backlight module 10 .

120: Determine a preset interference position in the blind hole, so that the preset interference position is located between the dispensing position and the electronic device to be installed in the blind hole, and the preset interference position is The spacing between the electronic devices is greater than or equal to a preset spacing.

The predetermined interference position 502 is determined in the blind hole 40 in order to be able to control the glue dispensing process for the display screen that needs to be mass-produced. The preset interference position 502 is located between the dispensing position 50 and the electronic device 401 to be installed in the blind hole 40 , which means that when the electronic device 401 is installed in the blind hole 40 , the preset interference position 502 is located at the dispensing position. 50 and the position on the electronic device 401 closest to the glue dispensing position 50 , and the preset interference position 502 is located on the connecting line between the glue dispensing position 50 and the position on the electronic device 401 closest to the glue dispensing position 50 .

The distance between the preset interference position 502 and the position on the electronic device 401 closest to the glue dispensing position 50 is greater than or equal to the preset distance. In other words, the preset distance needs to ensure that the colloid at the preset interference position 502 does not interfere with the electronic device 401 . The preset spacing can be set by the manufacturer according to the size of the blind hole 40 and the size of the electronic device 401 . The preset interference position 502 may be determined according to the preset distance. In the present application, the preset spacing is a reasonable range value, and the preset spacing enables the contour of the colloid to be located at the preset interference position 502 without interfering with the electronic device 401 . At the same time, the electronic device 401 and the display screen can be installed compactly.

130: Determine a target position on the colloid contour surface corresponding to the preset interference position.

Since the target position 501 is compared with the preset interference position 502, it is determined whether the dispensing process is qualified. Therefore, the target position 501 has a corresponding relationship with the preset interference position 502 . In one embodiment, the corresponding relationship between the preset interference position 502 and the target position 501 may be that the target position 501 is located on the connecting line between the glue dispensing position 50 and the preset interference position 502 . After the preset interference position 502 is determined, the corresponding target position 501 can be determined according to the connection line between the glue dispensing position 50 and the preset interference position 502 .

In addition, since the target position 501 is a point on the contour surface of the colloid. Therefore, there are two cases for the target position 501 . The first is that the target position 501 is located between the dispensing position 50 and the preset interference position 502 . In the second type, the target position 501 is located on the extension line of the glue dispensing position 50 and the preset interference position 502 , and is close to the preset interference position 502 .

140: Detecting whether the target position is located between the dispensing position and the preset interference position, if the detection result is yes, the dispensing process is qualified; if the detection result is no, the dispensing process Failed.

When the target position 501 is located between the dispensing position 50 and the preset interference position 502, it means that the distance between the target position 501 and the electronic device 401 is greater than or equal to the distance between the preset interference position 502 and the electronic device 401. It is assumed that the interference position 502 does not interfere with the electronic device 401 , so the colloid profile at the target position 501 does not interfere with the electronic device 401 , and it is judged that the dispensing process is qualified.

When the target position 501 is located on the extension line between the dispensing position 50 and the preset interference position 502, and is close to the preset interference position 502, it means that the distance between the target position 501 and the electronic device 401 is smaller than the distance between the preset interference position 502 and the electronic device 401, so the colloid at the target position 501 interferes with the electronic device 401, and it is judged that the dispensing process is unqualified.

In one embodiment, detecting whether the target position 501 is located between the dispensing position 50 and the preset interference position 502 may be to compare the coordinate value of the target position 501 with the coordinate value of the preset interference position 502 .

By dispensing glue at the dispensing position 50 in the blind hole 40 of the base material to form a colloid, and then checking whether the dispensing process is qualified or not, it is judged whether the colloid interferes with the electronic device 401, so that the yield of the product can be improved and the product can be timely. Adjustments for defective products. In addition, the preset interference position 502 and the target position 501 are determined in the blind hole 40, and by judging the relationship between the target position 501 and the preset interference position 502, mass-produced products can be detected, and the detection process is simple and reliable .

Please refer to FIG. 5 , which is a schematic flowchart of the dispensing management and control method provided by the second embodiment of the present application. The dispensing control method includes at least the following steps:

210 : disposing a liquid crystal substrate on the backlight module to form a base material; forming blind holes on the base material, so that the blind holes penetrate through the backlight module, and the liquid crystal substrate faces the backlight module. The bottom surface of the blind hole is formed on the surface, so that the connection between the inner wall of the blind hole and the liquid crystal substrate forms a glue dispensing position; glue is dispensed on the glue dispensing position to form a colloid.

Wherein, please refer to FIG. 3 , the base material at least includes a backlight module 10 and a liquid crystal substrate 20 . The liquid crystal substrate 20 includes a color filter substrate, a liquid crystal and a thin film transistor array substrate that are stacked in sequence.

In the embodiment of the present application, it is assumed that the length direction of the substrate is along the X-axis direction. The thickness direction of the base material is along the Y-axis direction.

The direction indicated by the arrow in Figure 3 is the positive direction.

The liquid crystal substrate 20 and the backlight module 10 are sequentially arranged along the positive Y axis. In other words, the backlight module 10 includes a bottom surface 101 and a side surface 102 adjacent to the bottom surface 101 . The liquid crystal substrate 20 has a first end surface 201 and a second end surface 202 arranged along the positive Y axis. The bottom surface 101 of the backlight module 10 is attached to the second end surface 202 of the liquid crystal substrate 20 .

The blind hole 40 penetrates through the backlight module 10 , and the bottom surface 101 of the blind hole 40 is formed on the surface of the liquid crystal substrate 20 facing the backlight module 10 . It can be understood that the blind holes 40 of the substrate are through holes provided on the backlight module 10 . The opening of the blind hole 40 is flush with the bottom surface 101 of the backlight module 10 , and the second end surface 202 of the liquid crystal substrate 20 forms the bottom surface 101 of the blind hole 40 . There is a gap between the second end surface 202 of the liquid crystal substrate 20 and the bottom surface 101 of the backlight module 10 . When dispensing and sealing the gap, the dispensing position 50 is located at the connection between the second end face 202 of the liquid crystal substrate 20 and the inner wall of the blind hole 40 .

When the glue is dispensed at the junction between the second end face 202 of the liquid crystal substrate 20 and the inner wall of the blind hole 40 , the formed glue is located between the second end face 202 of the liquid crystal substrate 20 and the bottom face 101 of the backlight module 10 or on the bottom face of the liquid crystal substrate 20 . between the second end surface 202 and the side surface 102 of the backlight module 10 .

220 : Determine a preset interference position on the connection line between the dispensing port of the dispensing valve and the dispensing position, so that the preset interference position and the electronic device to be installed in the blind hole are connected. The distance between them is greater than or equal to a preset distance; the preset interference position includes a first coordinate and a second coordinate, and the first coordinate is the distance between the preset interference position and the inner wall of the blind hole; The second coordinate is the distance between the preset interference position and the liquid crystal substrate.

In this embodiment, please refer to FIG. 3 and FIG. 4 , the determination of the predetermined interference position 502 is based on the fluidity principle of glue. Specifically, when the dispensing process is performed through the dispensing valve, the position of the dispensing valve is fixed. According to the fluidity principle of glue, the position opposite to the dispensing port of the dispensing valve is the most prominent position of the contour surface of the glue. The most protruding position of the colloidal profile surface is also the position most likely to interfere with the electronic device to be installed in the blind hole. Due to the fluidity of the glue, the most protruding position is always located on the connecting line between the dispensing port of the dispensing valve and the dispensing position 50 . In other words, the preset interference position 502 is also located on the connecting line between the dispensing port of the dispensing valve and the dispensing position 50 .

Because the preset interference position 502 is located on the connection line between the dispensing port of the dispensing valve and the dispensing position 50 , and the distance from the electronic device 401 to be installed in the blind hole 40 is a preset distance. Therefore, after the positions of the dispensing valve and the dispensing position 50 are determined, the preset interference position 502 can be determined in combination with the preset distance. In one embodiment, the preset spacing is greater than or equal to 0.15 mm, and the preset spacing is less than or equal to 0.3 mm.

If the glue dispensing position 50 is taken as the origin, the first coordinate is the absolute value of the X coordinate of the preset interference position 502 . The second coordinate is the absolute value of the Y coordinate of the preset interference position 502 .

230 : Determine a target position on the connecting line between the glue dispensing port of the glue dispensing valve and the glue dispensing position, so that the target position is located at the intersection point of the colloid contour surface and the connecting line.

Referring to FIGS. 3 and 4 , according to the preset interference position 502 determined in the above step 202 , it can be determined that the target position 501 corresponding to the preset interference position 502 is located at the dispensing port and the dispensing position of the dispensing valve. 50 between the connecting lines. The target position 501 determined by the intersection point of the connecting line and the colloid contour surface is the most prominent point on the colloid contour surface.

240 : Scan the contour surface of the second colloid by laser, and obtain the target distance between the preset interference position and the target position; obtain according to the target distance, the first coordinate and the second coordinate The third and fourth coordinates of the target position, the third coordinate is the distance between the target position and the inner wall of the blind hole; the fourth coordinate is the target position and the liquid crystal distance between substrates.

The target position 501 is a point on the contour surface of the colloid, so the target position 501 is related to the amount of colloid dispensed during the dispensing process. When the dispensing process is completed, the outline and size of the colloid can be obtained by a laser profiler. Thus, the third and fourth coordinates of the target position 501 are obtained.

In one embodiment, a beam of light is emitted in the direction of the target position 501 through the preset interference position 502, and when the beam of light contacts the colloid contour surface, the corresponding light will be reflected back to the preset interference position 502, and the emitted light and the time difference between the reflected rays to determine the distance between the target position 501 and the preset interference position 502 . The third and fourth coordinates of the target position 501 can be obtained according to the coordinates of the preset interference position 502 and the distance between the preset interference position 502 and the target position 501 .

If the glue dispensing position 50 is taken as the origin, the third coordinate is the absolute value of the X coordinate of the target position 501 . The fourth coordinate is the absolute value of the Y coordinate of the target position 501 .

250: Determine whether the third coordinate is less than or equal to the first coordinate, and whether the fourth coordinate is less than or equal to the second coordinate, when the third coordinate is less than or equal to the first coordinate, and When the fourth coordinate is less than or equal to the second coordinate, it is determined that the dispensing process is qualified; when the third coordinate is greater than the first coordinate or the fourth coordinate is greater than the second coordinate, Then it is determined that the dispensing process is unqualified.

In this embodiment, the third coordinate and the first coordinate respectively represent the distance along the X-axis between the target position 501 , the preset interference position 502 and the coordinate origin, and the coordinate values of the second coordinate and the fourth coordinate are positive numbers. The fourth coordinate and the second coordinate respectively represent the distance along the Y-axis direction between the target position 501 , the preset interference position 502 and the coordinate origin, and the coordinate values of the second coordinate and the fourth coordinate are positive numbers.

In one embodiment, by comparing the magnitudes of the first coordinate and the third coordinate, it can be determined whether the target position 501 is located between the dispensing position 50 and the preset interference position 502 in the X-axis direction, that is, in the X-axis direction Whether the colloid will interfere with the electronic device 401 .

By comparing the size of the second coordinate and the fourth coordinate, it can be determined whether the target position 501 is located between the dispensing position 50 and the preset interference position 502 in the Y-axis direction, that is, whether the colloid will interact with the electronic device in the Y-axis direction. 401 Interference.

When the third coordinate is less than or equal to the first coordinate, and the fourth coordinate is less than or equal to the second coordinate, the detection result is yes, and it is judged that the dispensing process is qualified, that is, the colloid is in the X-axis direction and the Y-axis direction. Device 401 is free of interference. When the size of the first coordinate and the third coordinate is detected first, if the third coordinate is greater than the first coordinate, it means that the colloid interferes with the electronic device 401 in the X-axis direction. If the test result is no, it is judged that the dispensing process is unqualified. When the size of the second coordinate and the fourth coordinate is detected first, if the fourth coordinate is greater than the second coordinate, there is no need to compare the size of the first coordinate and the third coordinate, and the detection result is directly obtained. qualified.

Products that fail the dispensing process are defective products, and products that pass the dispensing process are good products, and the good products and cameras are installed later.

In another embodiment, if the glue dispensing position 50 is taken as the origin of the coordinates, according to the determination method of the preset interference position 502 and the target position 501, it indicates that the glue dispensing position 50, the preset interference position 502 and the target position 501 are on the same straight line , then when the third coordinate is less than or equal to the first coordinate, it can be determined that the fourth coordinate is also less than the second coordinate, that is, the detection result is directly obtained. When the third coordinate is greater than the first coordinate, it can be judged that the fourth coordinate is greater than the second coordinate, and the detection structure is directly obtained. In this embodiment, it is only necessary to determine the size relationship of the coordinates in any direction in the X direction or the Y direction, so the detection time can be shortened, thereby improving the efficiency of the dispensing management and control method.

In this embodiment, the blind holes 40 are formed on the backlight module 10, so that the protective edges required to be arranged around the blind holes 40 are reduced, thereby reducing the black edges on the display screen and improving the visual effect. The preset interference position 502 and the target position 501 are determined on the connecting line between the dispensing port of the dispensing valve and the dispensing position 50, and the obtained target position 501 is the highest point on the colloid contour surface, which can improve the accuracy of the detection result. sex. In addition, by comparing the coordinate values of the target position 501 and the preset position, it is judged whether the dispensing process is qualified or not. Since it is easier to obtain the coordinate value, the dispensing control method is easy to implement.

Please refer to FIG. 6 and FIG. 7 . FIG. 6 is a schematic flowchart of the glue dispensing management and control method provided by the third embodiment of the present application. The difference between this embodiment and the second embodiment above is that two colloids are formed by dispensing glue at the connection between the liquid crystal substrate 20 and the inner wall of the hole of the blind hole 40 .

The dispensing control method includes at least the following steps:

310: Disposing a liquid crystal substrate on the backlight module to form a base material;

Blind holes are formed on the base material, so that the blind holes penetrate through the backlight module, and the bottom surface of the blind holes is formed on the surface of the liquid crystal substrate facing the backlight module, so that the holes of the blind holes are formed. A glue dispensing position is formed at the connection between the inner wall and the liquid crystal substrate;

A first colloid is formed between the liquid crystal substrate and the backlight module through the blind hole; a second colloid is formed between the liquid crystal substrate and the inner wall of the blind hole through the blind hole.

Please refer to FIG. 6 and FIG. 7 , wherein the first colloid 301 seals and connects the liquid crystal substrate 20 and the bottom surface 101 of the backlight module 10 (refer to FIG. 3 ). The second glue 302 seals and connects the liquid crystal substrate 20 and the side surface 102 of the backlight module 10 (refer to FIG. 3 ).

Specifically, the first colloid 301 is located between the second end surface 202 of the liquid crystal substrate 20 and the bottom surface 101 of the backlight module 10 . In other words, the first colloid 302 is substantially parallel to the X-axis.

In one embodiment, by tilting the base material at a first angle, the glue dispensing position 50 is set at a position corresponding to the glue dispensing valve, and the base material is rotated so that the glue dispensing valve is aligned with the glue dispensing valve. The glue dispensing position 50 dispenses glue to form a first colloid 301 , the first angle is greater than or equal to 0°, and the first angle is less than or equal to 10°. In this embodiment, by fixing the dispensing valve, the substrate is rotated to obtain the first colloid 301 approximately parallel to the X-axis. The first colloid 301 seals the liquid crystal substrate 20 and the backlight module 10 along the X-axis direction.

Specifically, the second colloid 302 is located between the second end surface 202 of the liquid crystal substrate 20 and the side surface 102 of the backlight module 10 . In other words, the second colloid 302 generally extends along the Y axis.

In one embodiment, the base material is inclined at a second angle, so that the connection between the first colloid 301 and the inner wall of the blind hole 40 is set at a position corresponding to the dispensing valve, and rotating the the base material, so that the dispensing valve dispenses glue on the connection between the first colloid 301 and the inner wall of the blind hole 40 to form a second colloid 302, and the second angle is greater than or equal to 40° °, and the second angle is less than or equal to 50°. In this embodiment, the base material is rotated by fixing the dispensing valve to obtain a second colloid 302 extending substantially along the Y axis. The second colloid 302 seals the liquid crystal substrate 20 and the backlight module 10 along the Y-axis direction.

In this embodiment, the first colloid 301 and the second colloid 302 are formed by sequentially dispensing glue at the connection between the liquid crystal substrate 20 and the inner wall of the blind hole 40 . It can be understood that the contour surface of the second colloid 302 is closer to the electronic device 401 than the contour surface of the first colloid 301 , that is, it is easier to interfere with the electronic device 401 . Therefore, in this embodiment, it is judged whether the second glue dispensing process is qualified. Therefore, in the subsequent steps, the colloid is replaced with the second colloid 302 , and the dispensing position 50 (refer to FIG. 4 ) is replaced with the first dispensing position 503 of the second colloid 302 . The first glue dispensing position 503 is located at the connection between the first glue 301 and the inner wall of the blind hole 40 . The first glue point 503 is shown in FIG. 7 .

320: Determine a preset interference position on the connection line between the dispensing port of the dispensing valve and the first dispensing position, so that the preset interference position and the electronic device to be installed in the blind hole The spacing between the devices is greater than or equal to the preset spacing; determine the first and second coordinates of the preset interference position, and the first coordinate is between the preset interference position and the side surface of the backlight module distance; the second coordinate is the distance between the preset interference position and the liquid crystal substrate.
