The present embodiment provides a method for screen light processing, which is used for light processing a screen 10. As shown in fig. 1, the screen 10 includes a first straight screen 101, a connection screen 103, and a second straight screen 102, which are connected in sequence, the first straight screen 101 and the second straight screen 102 are disposed opposite to each other, a separation cavity is formed between the first straight screen 101 and the second straight screen 102, and an area to be processed 105 is disposed on the upper edges of the first straight screen 101 and the second straight screen 102.
Specifically, as shown in fig. 2, the method of screen light processing includes:
s1, coating a light reaction coating on one side, facing to the second straight screen 102, of the first straight screen 101;

In the screen light processing method provided by the embodiment, the laser beam firstly passes through the second straight screen 102 and irradiates to the light reaction coating on the first straight screen 101, and then the light reaction coating on the second straight screen 102 is subjected to light processing through the spacer cavity, so that the operation difficulty and complexity of the light processing are reduced, the production time is reduced, the area of the light processing through the spacer cavity is reduced, the accuracy of the light processing position is improved, the qualification rate of the product is ensured, and the production cost is reduced.
Fig. 3 is a flowchart illustrating detailed steps of the method for processing the screen light provided in this embodiment, and the method for processing the screen light provided in this embodiment is described in detail below with reference to fig. 3. The method comprises the following steps:
and S1, coating a photoreaction coating on the side, facing the second straight screen 102, of the first straight screen 101.
Specifically, the photoreactive coating is a photoresist. In this embodiment, before step S1, the method further includes washing the screen 10 and drying. Specifically, the cleaning may be carried out using ultrapure water or ethanol.
As shown in fig. 4, in the optical processing apparatus 1 used in the present embodiment, the optical processing apparatus 1 includes a light source 2 and a stage 3. Specifically, after step S1, the second straight screen 102 is placed toward the light source 2 on the light processing device 1. The screen 10 is sucked on the stage 3 by a suction cup on the stage 3, and the light source 2 is arranged above the stage 3. The light source 2 is an exposure head of an exposure apparatus, which emits an ultraviolet laser beam capable of forming a light blocking area on the screen 10 when the laser beam is irradiated onto the photoresist. The first straight screen 101 faces downward and is placed on the stage 3, so that optical processing can be performed on the first straight screen 101 conveniently.
S2, the laser beam emitted from the light source 2 irradiates the second straight screen 102 perpendicularly to irradiate the photoreactive coating in the region 105 to be treated on the first straight screen 101 after passing through the second straight screen 102.
Specifically, since the screen is made of glass, the laser beam can pass through the second straight screen 102 to perform a photo-processing on the first straight screen 101. The laser beam passes through the second straight screen 102 and irradiates to the photoreaction coating on the first straight screen 101 to form a light resistance layer required on the screen 10, so that the area for carrying out light treatment through the spacer cavity is reduced, the accuracy of the light treatment position is improved, the qualification rate of products is ensured, and the production cost is reduced. In the present embodiment, the first straight screen 101 is rectangular, and the area to be processed 105 on the first straight screen 101 is disposed along three straight edges of the first straight screen 101 in a U shape.
And S3, coating a photoreaction coating on the side, facing the first straight screen 101, of the second straight screen 102.
The photoreaction coatings on the first straight screen 101 and the second straight screen 102 are coated separately, so that when the first straight screen 101 is subjected to photo-processing, no photoreaction coating on the second straight screen 102 prevents a laser beam from passing through the second straight screen 102 to irradiate the first straight screen 101, the area for performing photo-processing through a spacing cavity is reduced, the accuracy of the position for the photo-processing is improved, the qualification rate of products is guaranteed, and the production cost is reduced. Specifically, the photoreactive coating is a photoresist.
Specifically, after step S3, the screen 10 is turned over so that the second straight screen 102 is disposed facing away from the light source 2. Specifically, the second straight screen 102 is directed to the stage 3 and is attached to the stage 3.
S4, the laser beam emitted by the light source 2 passes through the spacing cavity to irradiate the photoreactive coating in the area 105 to be processed, which is the area opposite to the first straight screen 101, of the second straight screen 102.
The placement after turning the screen 10 in step S3 is also convenient for the laser beam to be irradiated from the compartment onto the second straight screen 102 in step S4. As shown in fig. 5 to 6, it can be understood that, because there is a facing portion between the second straight screen 102 and the first straight screen 101, and a light blocking layer has been formed on the first straight screen 101, the laser beam cannot directly pass through the first straight screen 101 to irradiate onto the second straight screen 102, the laser beam can only obliquely irradiate onto the second straight screen 102 from the spacing cavity between the first straight screen 101 and the second straight screen 102, and the laser beam obliquely enters at an angle with respect to the second straight screen 102. The inclination angle of the laser beam is related to the distance H between the first straight screen 101 and the second straight screen 102 and the width L of the region to be processed 105, and the inclination angle is adaptively adjustable. It is understood that when the laser beam is irradiated to the photoreactive coating in the region 105 to be processed on the second straight screen 102, a photoresist layer is already formed on the first straight screen 101, but the thickness of the photoresist layer is negligible, which is only illustrated in fig. 5. In this embodiment, the second straight screen 102 is rectangular, and the region to be processed 105 on the second straight screen 102 is in two opposite straight lines along the edges of the two opposite straight edges. And the length direction of the second straight screen 102 is the same as the length direction of the first straight screen 101, the region to be processed 105 on the second straight screen 102 is arranged on two straight sides arranged in the width direction on the second straight screen 102. It should be noted that, in fig. 5, for clarity, the region to be processed 105 is shown, the first straight screen 101 is in a perspective view, the region to be processed 105 is disposed on a surface of the first straight screen 101 opposite to the second straight screen 102, and the region to be processed 105 is shown in a shadow. The laser beam is indicated by four straight arrows. In addition, only a partial structure of the left area of the first and second straight screens 101 and 102 in fig. 1 is shown in fig. 6.
Further, the optical processing apparatus 1 provided in this embodiment further includes a stage rotating member and a light source rotating member, both the stage rotating member and the light source rotating member are driving motors, and can drive the stage 3 and the light source 2 to rotate, so that the laser beam can be conveniently inclined to irradiate the second straight screen 102 through the spacing cavity, and the angle between the second straight screen 102 and the light source 2 can be conveniently changed.
In this embodiment, the second straight screen 102 is partially opposite to the first straight screen 101, and the second straight screen 102 has a non-blocking area far away from the connecting screen 103 and protruding from the first straight screen 101 along a direction parallel to the first straight screen 101. That is, one end of the second straight screen 102 away from the connecting screen 103 has a non-blocked area protruding from the first straight screen 101 in a direction parallel to the first straight screen 101, that is, the second straight screen 102 is wider than the first straight screen 101 in the width direction. Therefore, step S4 further includes:
s41, the laser beam emitted by the light source 2 irradiates the photoreactive coating on the area to be processed 105, which is protruded from the non-blocked area of the first straight screen 101, of the second straight screen 102.
The laser beam passes through the spacing cavity and irradiates to the area, opposite to the first straight screen 101, of the second straight screen 102, then the laser beam directly irradiates to the area, protruding out of the first straight screen 101, of the second straight screen 102, and the S4 and the S41 are operated separately, so that the accuracy of the light processing position in the protruding area of the second straight screen 102 in the S41 can be guaranteed, the accuracy of the light processing position is improved, the qualified rate of products is guaranteed, and the production cost is reduced.
In some embodiments, in step S41, the laser beam of the light source 2 is obliquely disposed to the second straight screen 102. Since the laser beam in the step S4 is obliquely arranged with respect to the second straight screen 102, the laser beam in the step S41 may also be extended with the oblique laser beam, thereby reducing the time for adjusting the angle of the laser beam, reducing the operation time, simplifying the operation process, and reducing the production cost. Of course, in some embodiments, in step S41, the laser beam of the light source 2 is disposed perpendicular to the second straight screen 102. In other embodiments, in step S41, the laser beam of the light source 2 may be alternatively disposed between the vertical disposition and the inclined disposition with the second straight screen 102, which is not limited herein. It is to be understood that when the angle of the laser beam is changed, it is possible to cause the stage rotator and the light source rotator to simultaneously drive the stage 3 to rotate and the light source 2 to rotate to adjust the angle of the laser beam, or to drive one of the stage 3 and the light source 2 to rotate to adjust the relative angle between the laser beam and the screen 10.
In this embodiment, the edge of the connection screen 103 is also provided with a region to be processed 105, which needs to be optically processed. In this embodiment, two to-be-processed regions 105 on the connection screen 103 are disposed along the edge, and the two ends of the C-shaped to-be-processed region 105 on the first straight screen 101 and the two straight-line-shaped to-be-processed regions 105 on the second straight screen 102 are correspondingly connected. Therefore, after step S4, the method further includes:
and S5, coating a photoreaction coating on the side, facing the compartment, of the connecting screen 103.
The photoreaction coatings of the connecting screen 103 and the first straight screen 101 and the second straight screen 102 are respectively coated, so that the photoreaction coatings on the connecting screen 103 cannot be mistakenly irradiated when the first straight screen 101 and the second straight screen 102 are processed, the accuracy of a light processing position is improved, the qualification rate of a product is ensured, and the production cost is reduced. Specifically, the photoreactive coating is a photoresist.
S6, the laser beam from the light source 2 passes through the compartment and irradiates the photoreactive coating on the connecting screen 103 in the area 105 to be treated.
In the present embodiment, in step S6, the laser beam of the light source 2 is obliquely arranged with respect to the second straight screen 102. Of course, in some embodiments, the laser beam emitted by the light source 2 may also be alternately arranged with the second straight screen 102 between a parallel arrangement and an inclined arrangement, which is more convenient for the laser beam to irradiate the connection screen 103, and is not limited herein.
Specifically, the cross section of the connection screen 103 is curved. Further, in step S6, the screen 10 is rotated along the curved contour of the joining screen 103 while the laser beam emitted from the light source 2 irradiates the photoreactive coating in the region 105 to be processed on the joining screen 103. The screen 10 is rotated along the contour of the connection screen 103, so that all parts of the area to be processed 105 in the connection screen 103 can be irradiated by laser beams in the process of optically processing the connection screen 103, and the qualification rate of products is ensured. In this embodiment, the cross section of the connection screen 103 is semicircular. When the connection screen 103 is processed using a laser beam, the stage rotator and the light source rotator may simultaneously rotate the stage 3 and the light source 2 to adjust the angle of the laser beam, or may rotate one of the stage 3 and the light source 2 to adjust the relative angle between the laser beam and the screen 10.
In this embodiment, a tail screen 104 is disposed at an end of the second straight screen 102 away from the connection screen 103, the cross section of the tail screen 104 is arc-shaped and is curved toward the first straight screen 101, and the tail screen 104 is provided with a region to be processed 105 along an edge. In this embodiment, a straight edge is disposed at an end of the tail panel 104 away from the second straight panel 102, two side edges are connected between the straight edge of the tail panel 104 and the second straight panel 102, the region to be processed 105 on the tail panel 104 is disposed along the edges of the straight edge and the two side edges, and the region to be processed 105 on the straight edge of the tail panel 104 is linear. It is understood that, since the tail screen 104 is disposed in a curved manner, the regions to be processed 105 on both sides are C-shaped. One end of each of the to-be-processed regions 105 on the two sides is respectively connected to the two to-be-processed regions 105 on the second straight panel 102, and the other end is connected to the to-be-processed region 105 on the straight edge of the tail panel 104. The areas to be processed 105 on the first straight screen 101, the connecting screen 103, the second straight screen 102 and the tail screen 104 are connected end to end so that the areas to be processed 105 on the screen 10 are in a ring shape. Preferably, after step S6, the method further includes:
and S7, coating a light reaction coating on the side, facing the compartment, of the tail screen 104.
The tail screen 104 and the photoreaction coatings of the first straight screen 101, the second straight screen 102 and the connecting screen 103 are respectively coated, so that the photoreaction coatings on the tail screen 104 cannot be mistakenly irradiated when the first straight screen 101, the second straight screen 102 and the connecting screen 103 are processed, the accuracy of a light processing position is improved, the qualification rate of a product is ensured, and the production cost is reduced. Specifically, the photoreactive coating is a photoresist. It can be understood that since the tail screen 104 is disposed to be curved toward the first straight screen 101, and the tail screen 104 is not coated with the photoreactive coating when the connection screen 103 is processed, the laser beam may pass through the tail screen 104, the laser beam parallel to the second straight screen 102 may not be always used when the connection screen 103 is optically processed, preventing the direction of the laser beam from being changed after passing through the curved tail screen 104.
S8, the laser beam emitted from the light source 2 irradiates the photoreactive coating on the tail screen 104 in the region 105 to be processed.
In the present embodiment, in step S8, the laser beam of the light source 2 is obliquely arranged with respect to the second straight screen 102. Of course, in some embodiments, in step S8, the laser beam of the light source 2 is disposed perpendicular to the second straight screen 102. In other embodiments, the laser beam of the light source 2 may be alternatively disposed between the vertical disposition and the inclined disposition with the second straight screen 102, so as to facilitate the laser beam to irradiate the tail screen 104, which is not limited herein. It is understood that when the angle of the laser beam needs to be changed, the stage rotator and the light source rotator may be made to simultaneously drive the stage 3 to rotate and the light source 2 to rotate to adjust the angle of the laser beam, or drive one of the stage 3 and the light source 2 to rotate to adjust the relative angle between the laser beam and the screen 10.
Further, in step S8, the screen 10 is rotated along the curved profile of the tail gate 104 while the laser beam emitted from the light source 2 irradiates the photoreactive coating in the region 105 to be processed on the tail gate 104.
Rotating the screen 10 along the profile of the tail screen 104 can ensure that all parts of the area to be processed 105 in the tail screen 104 can be irradiated by laser beams in the process of optically processing the tail screen 104, thereby ensuring the qualification rate of products. When the tail screen 104 is processed using the laser beam, the stage rotator and the light source rotator may simultaneously rotate the stage 3 and the light source 2 to adjust the angle of the laser beam, or may drive one of the stage 3 and the light source 2 to rotate to adjust the relative angle between the laser beam and the screen 10.
Preferably, after step S8, a step of cleaning the screen 10 is further included. And cleaning to remove the excess photoreactive material on the photoreactive coating of the screen 10 after laser irradiation.
It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
