In the process of manufacturing large-size flexible panels, a laser linear spot with a large aspect ratio and high uniformity is required. By scanning the sacrificial layer material of the panel with this spot, the display device and the carrier substrate can be peeled off with low damage and high efficiency. How to detect whether the spot meets the aforementioned uniformity requirements requires detection to guide the optical system that generates the spot.

However, it should be clearly understood that the drawings are for illustration and description purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not drawn to scale.

[0020] The present application is described in detail below through specific embodiments.

[0021] Based on the above, refer to Figure 1~Figure 3 :The embodiment of the present application provides a method for detecting a long light spot, which is applied to a light spot detection system. The light spot detection system includes: a control device and a light source, a lens assembly, a sensor assembly and a guide rail assembly electrically connected to the control device; the sensor assembly is movably connected to the guide rail assembly, and the lens assembly and the sensor assembly are arranged relative to each other; The detection method comprises the steps of: S100, based on the light spot area formed by the light source output, locating the starting light spot position through the lens assembly; S200, collecting starting light spot data from the starting light spot position according to a preset length, and establishing a light spot storage library according to the starting light spot data; S300, taking the initial spot data as the starting point, according to a preset moving length, controlling the sensor assembly to step along a preset path on the guide rail assembly, and controlling the sensor assembly to perform a collection action; S400, when the length of the light spot data collected by the sensor component meets the measurement requirement, writing the collected light spot data into a light spot storage library; S500, obtaining the collection status of the light spot area and making a state judgment on the collection status; S600: If the acquisition status is that the acquisition of the entire light spot area is completed, the multiple light spot data in the light spot storage library are analyzed to obtain a distribution map of the entire light spot area.

[0022] Exemplarily, the lens assembly 102 in the optical path includes a plurality of cylindrical lenses and a microlens array, and the cylindrical lenses are used to reflect the light spot after passing through the reflector. The sensor assembly includes a light spot analyzer 103 and its sensor. For example, the existing light spot analyzer of model BFN0310UK-Basic can be used, which is not limited here. The light source is a laser light source, i.e., an excimer laser, which is used to emit the target light spot to be detected. After the incident laser passes through the attenuation module, the light beam is expanded and homogenized along the long axis, expanded and homogenized along the short axis, and finally focused and projected on the imaging surface 100. The lens assembly 102 can appropriately adjust the number of lenses and the position of the lenses according to the actual imaging effect. The sensor of the light spot analyzer 103 can be adjusted up and down, so that the light spot 101 passes through the lens assembly 102 and is clearly imaged on the light spot analyzer 103, and finally forms a linear light spot 101. Because the spot size is large, and the sensor of the spot analyzer 103 is not enough to obtain all the spots at one time, a parallel guide rail 104 that can move left and right can be installed on the base of the spot analyzer 103. By providing the guide rail, after adjusting the vertical position of the sensor, there is no need to adjust it again, which can reduce the error caused by manual displacement. Therefore, when the other parts of the optical system have been installed and adjusted, it is avoided to move, and the initial spot graphic data of the preset length is collected and saved by the sensor. The slider of the guide rail drives the sensor to step in sequence. At the same time, the sensor component is measured and saved when the collection requirements are met, until all the spot measurements are saved, and the entire linear spot diagram can be obtained after analyzing and processing the saved graphic data.

[0023] In some embodiments, when the length of the light spot data collected by the sensor assembly meets the measurement requirements, the collected light spot data is written into the light spot storage repository, including: The actual step length of the guide rail assembly and the length of the spot data collected by the sensor assembly are obtained, and it is determined whether the length of the collected spot data is valid; specifically, the sensor of the spot analyzer 103 can obtain an image with a length of L0 and a width of W0 at one time, that is, the measurable size is L0*W0, and the linear spot length is L, which is much larger than L0, and the width is W, which is smaller than W0, that is, see Figure 2 and Figure 3 The spot analyzer can fully image in the vertical direction and partially image in the horizontal direction.

[0024] When the length of the acquired spot data is less than the actual step length, the length of the acquired spot data is determined to be valid, and the acquired spot data is written into the spot database. Specifically, the spot pattern data of length x0 is acquired and saved each time, where x0 < L0, and the step length measured by the spot analyzer each time is x, x<x0, so that there is an overlapping area of ​​the light spots measured twice, avoiding the incomplete measurement of the interval area due to step error.

[0025] In some embodiments, obtaining the acquisition state of the light spot area and performing state judgment on the acquisition state include: Obtain the total length of the spot area, and calculate the reference step number according to the total length and the preset length; Obtain the motion state of the sensor component, and obtain the actual number of steps according to the motion state; Determine whether the actual number of steps meets the reference number of steps; If the actual number of steps reaches the reference number of steps, it is determined that the entire spot area is completely collected.

[0026] In some embodiments, based on the spot area formed by the light source output, the starting spot position is located through the lens assembly, including: based on the spot area formed by the light source output, detecting the incident position corresponding to the light source; adjusting the relative positions of the lens assembly and the sensor assembly according to the incident position, so that the sensor assembly locates the starting spot position through the lens assembly.

[0027] For example, see Figure 1~Figure 3 The optical system generates a light spot with a length of 750mm and a width of only 0.25mm. When using a light spot analyzer for detection, the entire light spot cannot be displayed completely at once. Therefore, a light spot detection method is required, in which the sensor component can use a light spot analyzer and its sensor to locate the starting light spot position and move along the long axis of the light spot. The sensor size is 13.1mm*9.8mm, and the light spot detection range is 32μm~13.1mm in the horizontal direction and can be fully detected in the vertical direction. The first imaging is the leftmost end of the light spot. The measurement range for each time is calculated as 13.1mm in width, and the step length is 10mm. The overlapping measurement area between the previous and next imaging is 3.1mm, which avoids the failure to measure the middle area completely due to step errors.

[0028] In some embodiments, if the acquisition status is that the acquisition of the entire light spot area is completed, then after analyzing the multiple light spot data in the light spot storage library to obtain the distribution map of the entire light spot area, it also includes: based on the distribution map of the entire light spot, analyzing and processing to obtain the light spot properties; analyzing and comparing the light spot properties with the preset ideal light spot to obtain the misalignment of the light spot.

[0029] Therefore, if Figure 3 As shown, multiple measurements are taken until the entire spot area is completely covered, and the spot graphics of each area are saved. After analysis and processing, the distribution effect diagram of the entire linear spot is obtained, and the spot properties are further obtained, that is, the collected image information is read to obtain the short axis and long axis distribution, power and direction. For example, Figure 4As shown in the figure, when the simulation obtains the preset ideal spot distribution diagram, the long axis information is obtained from the ideal spot diagram, which is the coordinate diagram below the spot, showing parallel distribution, and its short axis information is shown in the coordinate diagram to the right of the spot, showing Gaussian distribution. The coordinates of the left and right ends of the spot are read out after splicing the collected images to obtain the pointing situation, that is, whether it is parallel distribution.

[0030] During actual analysis, the actual light spot attribute analysis diagram is compared with the ideal distribution diagram to obtain the misalignment amount such as whether the distribution is uniform and parallel. For example, if a large inflection point or fluctuation appears in a certain section or multiple ends of the light spot diagram, it can be judged that the distribution is uneven. If the corresponding relationship of various attributes is greatly different after comparison, it can be concluded that the optical system needs to be re-adjusted. If the difference is small and the uniformity meets the requirements, no adjustment is required. The misalignment amount is used to judge whether the actual light spot meets the use requirements and whether the optical system needs to be adjusted again. At the same time, if the difference is small, the indicators detected are sufficient, and there is no need to adjust again, which can improve the use efficiency and avoid the situation where the light beam generated by the optical system is not used for target peeling or annealing without detection.

[0031] Therefore, the utilization efficiency of the laser spot can be improved by obtaining the misalignment amount of the light spot to guide and adjust the optical system.

[0032] In some embodiments, when detection cannot be performed from below during use, or real-time monitoring is required, for example, when the light source is emitted from top to bottom, a first guide rail 205 and a second guide rail 204 can be set on the guide rail assembly, the first guide rail 205 and the second guide rail 204 are vertically arranged, the second guide rail 205 is connected to the slider on the first guide rail 204, the light source is arranged above the first guide rail 204 and the second guide rail 205, the lens assembly includes a reflector 201, the sensor assembly 203 and the reflector 201 are connected to the slider of the second guide rail 204, and the reflector 201 and the sensor assembly 203 are arranged opposite to each other, wherein the reflector 201 is used to change the path of light according to a preset angle, and can be adjusted to a beam splitter, for example, 99% of the light is transmitted, and 1% of the light is incident on the sensor assembly 203 after being reflected by the beam splitter.

[0033] In this way, step S300 specifically includes: taking the initial spot data as the starting point, according to a preset stepping length, controlling the sensor assembly 203 to step left and right along the length direction of the first guide rail 205 or to step up and down along the length direction of the second guide rail 204, and controlling the sensor assembly 203 to perform the acquisition action. Specifically, Figure 5As shown, the light spot imaging is performed by reflection, that is, when the light beam 200 generated by the optical system is incident from above, it passes through the lower reflector 201 and the imaging lens group 202 and then enters the sensor assembly 203. Similarly, it is not enough to measure all the light spots at one time, and it is necessary to adopt the above-mentioned light spot detection method for step-by-step scanning measurement. The step-by-step movement depends on the second guide rail 204 that can move up and down and the first guide rail 205 that can move left and right. It depends on the specific position of the light spot. The position of the sensor is adjusted up and down and left and right. Each time, part of the light spot is collected. In other words, under the movement of the slider of one of the guide rails, the camera of the sensor assembly is driven to move along the parallel direction of the light beam, and the actual distribution diagram of the light spot presented by the light beam is gradually obtained, so that two-way light spot data collection can be realized. Until all the light spots are measured and saved, the light spots can be integrated and analyzed to obtain the comparison results.

[0034] Therefore, real-time online detection can be performed when the entire optical system is in use. By observing the distribution of the light spot and whether any abnormality occurs in real time, the optical system can be adjusted or shut down as soon as possible if any abnormality occurs.

[0035] In addition, in some embodiments, when only detection is required below the light source, the guide rail assembly can be configured as a mounting plate 302 and a third guide rail 303 fixed on the mounting plate 302, the light source is disposed above the third guide rail 303, the slider of the third guide rail 303 is connected to the sensor unit 304 and the imaging lens assembly 301, the imaging lens assembly 301 is disposed above the sensor unit 304, and the sensor unit 304 is controlled to step along a preset path on the guide rail assembly based on the starting light spot data as the starting point and according to a preset moving length, the sensor unit 304 is controlled to perform an acquisition action, including: using the starting light spot data as the starting point and according to a preset moving length, the sensor unit 304 is controlled to step along the length direction of the third guide rail 303 and the sensor unit 304 is controlled to perform an acquisition action.

[0036] For example, when a large-size linear light spot 300 is incident from above the sensor unit 304 for acquisition measurement, Figure 6 As shown, an imaging lens assembly 301 and a sensor unit 304 may also be arranged at the bottom thereof, the sensor unit 304 is fixed on the third guide rail 303, the third guide rail 303 is located on the fixed mounting plate 302, similarly, it is not enough to measure all the light spots at one time, and it is necessary to adopt the above-mentioned detection method for step scanning measurement, each time a part of the light spots is collected, and the camera of the sensor unit 304 on the third guide rail 303 moves along the direction parallel to the light spots until all the light spots are measured, and then the light spots are integrated and analyzed to obtain comparison results.
