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. The embodiments in the present application may be combined as appropriate.
As shown in fig. 1, an embodiment of the present application provides an electronic device 100. The electronic device 100 has a feature of a high screen occupation ratio. The electronic device 100 may be a mobile phone, a tablet computer, a notebook computer, a smart watch, or the like. The embodiment of the present application takes a mobile phone as an example for illustration. In order to realize higher screen occupation ratio, devices such as mobile phones need to solve the problem of arrangement of a receiver, a front camera and the like.
In a method for increasing the screen occupation ratio of the electronic device 100, the electronic device 401 is hidden in the display screen of the electronic device 100, so that the screen occupation ratio of the electronic device 100 is increased.
In other words, the electronic device 100 provided in the embodiment of the present application has a display screen and an electronic device 401, the display screen is provided with the blind hole 40, and the electronic device 401 is partially or completely 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, partially or completely hiding the electronic device 401 in the display screen means that a blind hole 40 is formed in 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 is located in the blind hole 40 of the display screen. The occupation ratio of the display area 103 of the display screen can be increased compared to the way in which the electronic device 401 is disposed on the non-display area 104.
The embodiment of the present application takes a hidden front camera as an example for explanation. To water droplet screen, bang screen and blind hole screen all hide leading camera in the display screen. In the electronic device 100, since the hole is formed in the display screen, a gap may occur around the hole, and light leakage is easy. The periphery of the hole of the display screen after the hole is opened is subjected to glue dispensing and sealing, the shooting effect of the front camera is guaranteed, one of the methods for solving the problem of light leakage of the display screen of the electronic equipment 100 is achieved, and the connection among the structures of the display screen can be reliable. However, if the display screen after the dispensing process is directly mass-produced, the glue body of the dispensing process has a risk of interfering with the front camera to be mounted, and the yield of the display screen after mass production cannot be guaranteed.

The dispensing control method provided by the embodiment of the present application will be explained in detail below with reference to the accompanying drawings.
As shown in fig. 2, fig. 2 is a schematic flow chart of a dispensing management and control method according to an embodiment of the present application. The dispensing control method at least comprises the following steps:
110: dispensing glue at the glue dispensing position in the blind hole of the substrate to form a glue body.
Referring to fig. 3 and fig. 4, the present application takes a liquid crystal display as an example for description, and details are not described later. The liquid crystal display screen at least comprises a glass cover plate, a liquid crystal substrate 20, a backlight module 10 and a fixing support which are arranged from top to bottom in sequence. The liquid crystal substrate 20 includes a color film substrate, a liquid crystal, and a thin film transistor array substrate, which are sequentially stacked. While the substrate represents the multilayer assembly in a liquid crystal display or represents the entire display.
The dispensing positions 50 are different for different opening manners. For example, when holes are formed in the liquid crystal substrate 20 and the backlight module 10 of the liquid crystal display panel, the gap between the glass cover plate layer and the liquid crystal substrate 20 may cause light leakage and backlight phenomena. Therefore, the space between the glass cover plate layer and the liquid crystal substrate 20 needs to be sealed by dispensing, and the dispensing station 50 represents the connection position between the glass cover plate layer and the inner wall of the hole. In another embodiment, when the backlight module 10 of the liquid crystal display panel is opened, the blind hole 40 penetrates 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, and the gap between the liquid crystal substrate 20 and the backlight module 10 needs to be sealed. At this time, the dispensing station 50 is a connection point between the liquid crystal substrate 20 and the inner wall of the hole.
It is understood that when the dispensing locations 50 are different, the locations of the formed glue are different. It is understood that when the dispensing station 50 is located at the connection between the glass cover plate layer and the inner wall of the hole, the glue formed by the dispensing process is located between the glass cover plate and the liquid crystal substrate 20. When the dispensing station 50 is located at the connection between the liquid crystal substrate 20 and the inner wall of the hole, the glue formed by the dispensing process is located between the liquid crystal substrate 20 and the backlight module 10.
120: and determining a preset interference position in the blind hole, so that the preset interference position is located between the dispensing position and an electronic device to be installed in the blind hole, and the distance between the preset interference position and the electronic device is larger than or equal to a preset distance.
The preset interference position 502 is determined in the blind hole 40 to control the dispensing process of the display screen requiring mass production. The preset interference position 502 is located between the dispensing position 50 and the electronic device 401 to be mounted in the blind hole 40, which means that when the electronic device 401 is mounted in the blind hole 40, the preset interference position 502 is located between the dispensing position 50 and a position on the electronic device 401 closest to the dispensing position 50, and the preset interference position 502 is located on a connection line between the dispensing position 50 and the position on the electronic device 401 closest to the dispensing position 50.
The distance between the preset interference position 502 and the position on the electronic device 401 closest to the dispensing position 50 is greater than or equal to the preset distance. In other words, the predetermined distance is required to ensure that the colloid at the predetermined interference position 502 does not interfere with the electronic device 401. The predetermined spacing may be set by the manufacturer based on the size of the blind vias 40 and the size of the electronic device 401. The predetermined interference position 502 may be determined according to a predetermined distance. In this application, the preset distance is a reasonable range value, and the preset distance enables the outline of the colloid to be located at the preset interference position 502 and not to interfere with the electronic device 401. While also making the electronics 401 compact to mount with the display screen.
130: and determining a target position corresponding to the preset interference position on the colloid contour surface.
Since the target position 501 is compared with the preset interference position 502, whether the dispensing process is qualified or not is determined. Thus, 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 a connecting line between the dispensing station 50 and the preset interference position 502. After the preset interference position 502 is determined, the corresponding target position 501 may be determined according to a connection line between the dispensing station 50 and the preset interference position 502.
In addition, the target position 501 is a point on the contour surface of the colloid. Thus, there are two cases of the target position 501. The first is that the target position 501 is located between the dispensing station 50 and the predetermined interference position 502. Secondly, the target position 501 is located on an extension line of the dispensing station 50 and the predetermined interference position 502, and is close to the predetermined interference position 502.
140: detecting whether the target position is located between the dispensing position and the preset interference position, wherein if the detection result is yes, the dispensing procedure is qualified; and if the detection result is negative, the dispensing procedure is unqualified.
When the target position 501 is located between the dispensing position 50 and the preset interference position 502, it indicates 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, and since the preset interference position 502 does not interfere with the electronic device 401, the colloid profile at the target position 501 does not interfere with the electronic device 401, and the dispensing process is determined to be qualified.
When the target position 501 is located on an extension line of the dispensing position 50 and the preset interference position 502 and is close to the preset interference position 502, it indicates 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, and therefore the colloid at the target position 501 interferes with the electronic device 401, and the dispensing process is determined to be unqualified.
In one embodiment, detecting whether the target position 501 is located between the dispensing station 50 and the preset interference position 502 may be comparing the coordinate value of the target position 501 with the coordinate value of the preset interference position 502.
Glue is dispensed through the glue dispensing positions 50 in the blind holes 40 of the base material to form glue, whether the glue dispensing process is qualified or not is detected, whether the glue interferes with the electronic device 401 or not is judged, and therefore the yield of the product can be improved, and the defective product can be adjusted in time. In addition, the preset interference position 502 and the target position 501 are determined in the blind hole 40, and the relationship between the target position 501 and the preset interference position 502 is judged, so that mass production products can be detected, and the detection process is simple and reliable.
Referring to fig. 5, fig. 5 is a flowchart illustrating a dispensing management and control method according to a second embodiment of the present application. The dispensing control method at least comprises the following steps:
210: arranging a liquid crystal substrate on the backlight module to form a base material; forming a blind hole on the base material, enabling the blind hole to penetrate through the backlight module, and enabling the liquid crystal substrate to face the surface of the backlight module to form the bottom surface of the blind hole, and enabling a joint between the inner wall of the blind hole and the liquid crystal substrate to form a dispensing position; dispensing glue on the dispensing positions to form a glue body.
Referring to fig. 3, the substrate at least includes a backlight module 10 and a liquid crystal substrate 20. The liquid crystal substrate 20 includes a color film substrate, a liquid crystal and a thin film transistor array substrate which are sequentially stacked.
The length direction of the base material is along the X-axis direction in the embodiment of the application. The thickness direction of the base material is along the Y-axis direction.
The direction indicated by the arrow in fig. 3 is the forward direction.
The liquid crystal substrate 20 and the backlight module 10 are sequentially arranged in the Y-axis forward direction. 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 face 201 and a second end face 202 arranged in the Y-axis forward direction. 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 a 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 is understood that the blind holes 40 of the substrate are through holes formed in 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. A gap is formed between the second end surface 202 of the liquid crystal substrate 20 and the bottom surface 101 of the backlight module 10. When the gap is sealed by dispensing, the dispensing station 50 is located at the connection between the second end surface 202 of the liquid crystal substrate 20 and the inner wall of the blind hole 40.
When dispensing is performed at the connection point between the second end surface 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 surface 202 of the liquid crystal substrate 20 and the bottom surface 101 of the backlight module 10 or between the second end surface 202 of the liquid crystal substrate 20 and the side surface 102 of the backlight module 10.
220: determining a preset interference position on a connecting line between a dispensing opening of the dispensing valve and the dispensing position, so that the distance between the preset interference position and an electronic device to be installed in the blind hole is larger than or equal to a preset distance; the preset interference position comprises 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 a distance between the preset interference position and the liquid crystal substrate.
In this embodiment, referring to fig. 3 and 4, the predetermined interference position 502 is determined based on the glue flowability principle. Specifically, when the dispensing process is performed through the dispensing valve, the position of the dispensing valve is fixed. According to the principle of fluidity of the glue, the position opposite to the glue dispensing opening of the glue dispensing valve is the most protruding position of the contour surface of the glue. The most protruding position of the glue profile is also the position where it is most likely to interfere with the electronic device to be mounted in the blind hole. Due to the fluidity of the glue, the most protruded position is always located on the connecting line of the glue dispensing opening of the glue dispensing valve and the glue dispensing position 50. In other words, the predetermined interference position 502 is also located on the connection line between the dispensing opening of the dispensing valve and the dispensing station 50.
The preset interference position 502 is located on a connecting line of the dispensing opening of the dispensing valve and the dispensing position 50, and the distance between the preset interference position and the electronic device 401 to be installed in the blind hole 40 is a preset distance. Therefore, when the positions of the dispensing valve and the dispensing station 50 are determined, the preset interference position 502 can be determined in combination with the preset distance. In one embodiment, the predetermined distance is greater than or equal to 0.15mm, and the predetermined distance is less than or equal to 0.3 mm.
If the dispensing position 50 is the origin, the first coordinate is the absolute value of the X coordinate of the predetermined interference position 502. The second coordinate is an absolute value of the Y coordinate of the preset interference position 502.
230: and determining a target position on a connecting line between the dispensing opening of the dispensing valve and the dispensing position, so that the target position is positioned at the intersection point of the colloid contour surface and the connecting line.
Referring to fig. 3 and 4, according to the predetermined interference position 502 determined in the step 202, it can be determined that the target position 501 corresponding to the predetermined interference position 502 is located on a connection line between the dispensing opening of the dispensing valve and the dispensing station 50. And 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: scanning the profile surface of the second colloid by laser, and presetting a target distance between the interference position and the target position; acquiring a third coordinate and a fourth coordinate of the target position according to the target distance, the first coordinate and the second coordinate, wherein the third coordinate is the distance between the target position and the inner wall of the blind hole; the fourth coordinate is a distance between the target position and the liquid crystal substrate.
The target position 501 is a point on the contour surface of the glue, and therefore the target position 501 is related to the amount of glue dispensed in the glue dispensing process. After the dispensing process is finished, the contour and the size of the colloid can be obtained through the laser profiler. Thereby obtaining a third coordinate and a fourth coordinate of the target position 501.
In one embodiment, a beam of light is emitted toward the target position 501 through the preset interference position 502, and when the beam of light contacts the colloid profile, the corresponding light is reflected back toward the preset interference position 502, and the distance between the target position 501 and the preset interference position 502 is determined by the time difference between the emitted light and the reflected light. The third coordinate and the fourth coordinate of the target position 501 may be obtained according to the coordinate of the preset interference position 502 and the distance between the preset interference position 502 and the target position 501.
If the dispensing position 50 is 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: judging whether the third coordinate is less than or equal to the first coordinate or not and whether the fourth coordinate is less than or equal to the second coordinate or not, and determining that the dispensing procedure is qualified 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; and when the third coordinate is larger than the first coordinate or the fourth coordinate is larger than the second coordinate, determining that the dispensing procedure is unqualified.
In this embodiment, the third coordinate and the first coordinate respectively represent distances between the target position 501, the preset interference position 502, and the origin of coordinates along the X-axis direction, and the coordinate values of the second coordinate and the fourth coordinate are positive numbers. The fourth coordinate and the second coordinate respectively represent distances between the target position 501, the preset interference position 502 and the origin of coordinates along the Y-axis direction, and coordinate values of the second coordinate and the fourth coordinate are positive numbers.
In one embodiment, comparing the magnitudes of the first coordinate and the third coordinate may determine whether the target position 501 is located between the dispensing position 50 and the preset interference position 502 in the X-axis direction, i.e., whether the glue would interfere with the electronic device 401 in the X-axis direction.
By comparing the magnitudes of the second coordinate and the fourth coordinate, it can be determined whether the target position 501 is located between the dispensing station 50 and the preset interference position 502 in the Y-axis direction, i.e., whether the adhesive body interferes with the electronic device 401 in the Y-axis direction.
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 the dispensing process is determined to be qualified, that is, the colloid has no interference with the electronic device 401 in both the X-axis direction and the Y-axis direction. When the first coordinate and the third coordinate are detected firstly, if the third coordinate is larger than the first coordinate, the colloid is interfered with the electronic device 401 in the X-axis direction, the sizes of the second coordinate and the fourth coordinate do not need to be compared again, whether the detection result is obtained directly is judged, and the dispensing procedure is judged to be unqualified. When the sizes of the second coordinate and the fourth coordinate are detected firstly, if the fourth coordinate is larger than the second coordinate, the sizes of the first coordinate and the third coordinate do not need to be compared, whether the detection result is obtained directly is judged, and the dispensing procedure is judged to be unqualified.
And the products unqualified in the dispensing process are defective products, the products qualified in the dispensing process are good products, and the good products and the camera are subsequently installed.
In another embodiment, if the dispensing station 50 is taken as the origin of coordinates, it is indicated that the dispensing station 50, the preset interference position 502 and the target position 501 are on the same straight line according to the determination manner of the preset interference position 502 and the target position 501, and when the third coordinate is smaller than or equal to the first coordinate, it can be determined that the fourth coordinate is smaller than the second coordinate, that is, the detection result is directly obtained as yes. When the third coordinate is larger than the first coordinate, the fourth coordinate is larger than the second coordinate, and whether the detection structure is directly obtained is judged. In this embodiment, only the magnitude relation of the coordinate in any direction in the X direction or the Y direction needs to be determined, so that the detection time can be shortened, and the efficiency of the dispensing control method is improved.
In the embodiment, the blind hole 40 is formed in the backlight module 10, so that the number of the protection edges required to be arranged around the blind hole 40 is reduced, the number of black edges on the display screen is reduced, and the visual effect is improved. The preset interference position 502 and the target position 501 are determined on a connecting line between the dispensing opening of the dispensing valve and the dispensing position 50, and the obtained target position 501 is the highest point on the colloid contour surface, so that the accuracy of the detection result can be improved. In addition, whether the dispensing process is qualified or not is judged by comparing the coordinate values of the target position 501 and the preset position, and the dispensing control method is easy to implement due to the fact that the coordinate values are easy to obtain.
Referring to fig. 6 and 7, fig. 6 is a schematic flow chart illustrating a dispensing management and control method according to a third embodiment of the present application. The difference between this embodiment and the second embodiment is that two glue layers are formed at the connection point between the liquid crystal substrate 20 and the inner wall of the blind hole 40.
The dispensing control method at least comprises the following steps:
310: arranging a liquid crystal substrate on the backlight module to form a base material;
forming a blind hole on the base material, enabling the blind hole to penetrate through the backlight module, and enabling the liquid crystal substrate to face the surface of the backlight module to form the bottom surface of the blind hole, and enabling a joint between the inner wall of the blind hole and the liquid crystal substrate to form a dispensing position;
forming a first colloid between the liquid crystal substrate and the backlight module through the blind hole; and forming a second colloid between the liquid crystal substrate and the inner wall of the blind hole through the blind hole.
Referring to fig. 6 and 7, the first sealant 301 is hermetically connected to the liquid crystal substrate 20 and the bottom surface 101 of the backlight module 10 (see fig. 3). The second sealant 302 is hermetically connected to the liquid crystal substrate 20 and the side surface 102 of the backlight module 10 (see fig. 3).
Specifically, the first adhesive 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, the substrate is tilted by a first angle, the dispensing station 50 is disposed at a position corresponding to the dispensing valve, and the substrate is rotated to dispense the dispensing station 50 with the dispensing valve, so as to form a first glue line 301, wherein the first angle is greater than or equal to 0 °, and the first angle is less than or equal to 10 °. In this embodiment, the first layer of colloid 301 is obtained by rotating the base material through the fixed glue valve, and is substantially parallel to the X-axis. The first sealant 301 seals the liquid crystal substrate 20 and the backlight module 10 in the direction along the X-axis.
Specifically, the second sealant 302 is located between the second end 202 of the liquid crystal substrate 20 and the side surface 102 of the backlight module 10. In other words, the second colloid 302 extends substantially along the Y-axis.
In an embodiment, the substrate is tilted by a second angle, so that the joint of the first glue 301 and the inner wall of the blind hole 40 is located at a position corresponding to the dispensing valve, the substrate is rotated, so that the dispensing valve dispenses the joint of the first glue 301 and the inner wall of the blind hole 40 to form a second glue 302, and the second angle is greater than or equal to 40 °, and is less than or equal to 50 °. In this embodiment, the substrate is rotated by fixing the glue valves to obtain a second lane of glue 302 extending substantially along the Y-axis. The second sealant 302 seals the liquid crystal substrate 20 and the backlight module 10 along the Y-axis direction.
In this embodiment, the first glue 301 and the second glue 302 are sequentially dispensed at the connection position between the liquid crystal substrate 20 and the inner wall of the blind hole 40.
