Description

Technical Field

[0001] The present disclosure relates to the field of electronic control technology, and in particular, to a quality signal tracking device and method. Background Art

[0002] Glass substrates are one of the key basic materials in the flat panel display industry, so the production process of glass substrates is extremely important. In the prior art, glass substrates usually need to go through multiple processing steps such as scribing, grinding, cleaning, and inspection before they can be finally packaged as finished products. In the production process of glass substrates, the quality of the glass substrates on the production line is required to be single, and glass substrates of different qualities cannot be mixed in. For example, if the quality of the glass substrates currently being processed on the production line is normal, then glass substrates of the quality of machine adjustment products or re-cleaned products cannot be mixed in.

[0003] However, in the related art, the quality of the glass substrate cannot be detected on the production line.

[0056] Transmission device 101 controls switch 102

[0057] Controller 103 Glass substrate 104 to be tested

[0058] Sensor 105 Display terminal 106 DETAILED DESCRIPTION

[0059] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0060] Before introducing the tracking device and method of the quality signal provided by the present disclosure, the application scenarios involved in the various embodiments of the present disclosure are first introduced. The application scenario can be a production line for glass substrates, where multiple groups of conveying equipment are arranged on the production line, each group of conveying equipment corresponds to a processing step, and the multiple groups of conveying equipment are arranged in the execution order of the corresponding processing steps, and the glass substrate to be tested passes through each group of conveying equipment to perform each processing step. The input port of each group of conveying equipment is connected to the output port of the previous group of conveying equipment in the group of conveying equipment, and the output port of each group of conveying equipment is connected to the input port of the next group of conveying equipment in the group of conveying equipment.

[0061] Figure 1a is a block diagram of a quality signal tracking device according to an exemplary embodiment. Figure 1a As shown, the device 100 includes: a transmission device 101, a control switch 102 and a controller 103. The transmission device 101 corresponds to one control switch 102, and the control switch 102 is connected to the controller 103.

[0062] The conveying device 101 is used to perform corresponding processing steps on the glass substrate 104 to be tested when the glass substrate 104 to be tested enters the input port of the conveying device 101 , and to convey the glass substrate 104 to the output port of the conveying device 101 after completing the processing steps.

[0063] The control switch 102 is used to send a control signal to the controller 103 . The control signal is sent by the user and is used to indicate the quality of the glass substrate 104 to be tested.

[0064] For example, in order to improve the production efficiency of glass substrates, when processing the glass substrates 104 to be tested, the quality of each glass substrate 104 to be tested can be distinguished in real time through the quality signal tracking device 100. When distinguishing the quality of the glass substrates 104 to be tested, the glass substrates 104 to be tested are firstly transported to the processing area through the conveying device 101, so that the processing area performs the processing steps on the glass substrates 104 to be tested. After the processing steps are completed on the glass substrates 104 to be tested, the conveying device 101 will transport the glass substrates 104 to the output port of the conveying device 101. In order to enable the glass substrates 104 to be tested to meet different industrial production requirements, the conveying device 101 set in the processing area can be a group (such as Figure 1a ), or multiple groups (such as Figure 1b As shown in FIG. 1 ), each group of conveying devices 101 corresponds to a processing procedure, and the processing procedure may be, for example, a scribing procedure, a grinding procedure, a cleaning procedure, an inspection procedure, etc. In a scenario where there are multiple groups of conveying devices 101, each group of conveying devices 101 may be connected end to end in the execution order of the corresponding processing procedures, that is, the output port of the conveying device 101 in the execution order is connected to the input port of the conveying device 101 in the execution order.

[0065] Specifically, each transmission device 101 corresponds to a control switch 102. If the transmission device 101 includes multiple groups of transmission devices, then the quality signal tracking device 100 has multiple control switches 102 corresponding to each transmission device 101. Each control switch 102 is connected to the controller 103 in the device 100, that is, the control switch 102 can send the control signal to the controller 103 through a physical connection (for example, a bus, a network cable, or an optical fiber). The controller 103 can be, for example, a DCS (Distributed Control System), a FCS (Field Bus Control System), a PLC (Program Logic Control), and the like.

[0066] The controller 103 is used to receive a control signal, and if a control signal is received, determine the quality signal according to the control signal; if no control signal is received, determine the quality signal according to a historical quality signal output by a previous transmission device.

[0067] The controller 103 is also used to output a quality signal.

[0068] For example, when the glass substrate 104 to be tested enters the input port of the conveying device 101, the user can send a control signal indicating the quality of the currently input glass substrate 104 to the controller 103 through the control switch 102, and the controller 103 receives the control signal. The control switch 102 may include a variety of buttons, which correspond to a variety of control signals. For example, the control switch 102 may include three buttons, which correspond to three control signals, i.e., control signals indicating that the glass substrate 104 to be tested is a normal product, a machine adjustment product, or a re-cleaned product. If the controller 103 receives the control signal, it means that the user has put in a glass substrate 104 to be tested that is different in quality from the glass substrate 104 to be tested that was previously put in at the input port of the conveying device 101, and the quality signal needs to be switched. Then, the quality signal can be directly determined according to the control signal, for example, the control signal can be directly used as the quality signal, or the control signal can be analyzed to obtain the quality of the glass substrate 104 to be tested, and then the quality signal is determined according to the quality of the glass substrate 104 to be tested, thereby realizing the detection and analysis of the quality of the glass substrate. If the controller 103 does not receive the control signal, it means that the quality of the glass substrate 104 to be tested put into the input port of the conveying device 101 remains unchanged, and the user has not put in a glass substrate 104 of other quality to be tested, then the controller 103 can determine the quality signal according to the historical quality signal output by the previous conveying device. The previous conveying device is a conveying device located before the current conveying device 101, that is, the output port of the previous conveying device is connected to the input port of the conveying device 101, and the previous conveying device conveys the glass substrate 104 to the output port after the glass substrate 104 to be tested completes the processing procedure corresponding to the previous conveying device, and then the glass substrate 104 to be tested enters the input port of the conveying device 101. The historical quality signal output by the previous conveying device can be understood as the quality signal of the glass substrate 104 to be tested determined by the previous conveying device, and the historical quality signal can be stored in the device 100, for example.

[0069] It should be noted that the quality signal is a signal for indicating the quality of the glass substrate 104 to be tested, and may include three quality signals for indicating that the glass substrate 104 to be tested is a normal product, a machine adjustment product, or a re-cleaned product. For example, the quality signal indicating a normal product is 0, the quality signal indicating a machine adjustment product is 1, and the quality signal indicating a re-cleaned product is 2. Further, if the conveying device 101 is the first conveying device on the production line, the corresponding historical quality signal may be set to a default signal (for example, a low-level signal "0" to indicate that the quality of the glass substrate 104 to be tested is a normal product), so that the controller 103 can still determine the quality signal of the glass substrate 104 to be tested when no control signal is received. In this way, when the glass substrate 104 to be tested leaves the output port of the conveying device 101, the quality signal of the glass substrate 104 to be tested can be output by the controller 103, so that the technical inspection personnel can quickly determine the quality of the glass substrate 104 to be tested.

[0070] like Figure 1a As shown, in a scenario with a group of conveying devices 101, when the glass substrate 104 to be tested enters the input port of the conveying device 101, the user can send a control signal for indicating the quality of the glass substrate 104 to be tested to the controller 103 through the control switch 102. The control signal can indicate whether the quality of the glass substrate 104 to be tested is a normal product, a machine adjustment product, or a re-cleaned product. For example, when the glass substrate 104 to be tested is a normal product, the control switch 102 can be left unpressed, that is, the default quality signal is 0. When the glass substrate 104 to be tested is a machine adjustment product, the button corresponding to the machine adjustment product in the control switch 102 can be pressed once to indicate that the quality of the glass substrate 104 to be tested is a machine adjustment product. When multiple glass substrates 104 to be tested placed continuously are all machine adjustment products, the button corresponding to the machine adjustment product in the control switch 102 can be pressed for a long time until the next glass substrate 104 to be tested is a normal product, and then the button pops up. When the glass substrate 104 to be tested is a re-cleaned product, the button corresponding to the re-cleaned product in the control switch 102 can be pressed to indicate that the quality of the glass substrate 104 to be tested is a re-cleaned product. When multiple glass substrates 104 to be tested placed continuously are all re-cleaned products, the button corresponding to the re-cleaned product in the control switch 102 can be long pressed until the next glass substrate 104 to be tested is a normal product, and then the button is popped up.

[0071] like Figure 1bAs shown, in a scenario with multiple groups of transmission devices 101, if the quality signal tracking device 100 includes 4 groups of transmission devices 101, then the device 100 includes 4 control switches 102, each group of transmission devices 101 corresponds to a control switch 102, and each group of transmission devices 101 corresponds to a processing procedure. Multiple groups of transmission devices 101 can be connected end to end in the execution order of the corresponding processing procedures, that is, the input port of each group of transmission devices 101 is connected to the output port of the transmission device 101 in the previous execution order, and the output port of each group of transmission devices 101 is connected to the input port of the transmission device 101 in the later execution order. When the glass substrate 104 to be tested is processed, the glass substrate 104 to be tested can be put into the input port of any processing process (i.e., any group of conveying devices), and the user only needs to press different buttons of the control switch 102 corresponding to the corresponding processing process according to the preset rules to send a control signal indicating the quality of the put-in glass substrate 104 to be tested to the controller 103, and the conveying device 101 can convey the glass substrate 104 to be tested to the output port of the group of conveying devices 101 after the glass substrate 104 to be tested has completed the remaining processing processes in sequence.

[0072] After the glass substrate 104 to be tested has completed all the processing steps, the quality level (e.g., good product, defective product, etc.) of the processed glass substrate can be determined by a technical inspector or a specific inspection device. For example, when the glass substrate 104 to be tested leaves the output port of the last group of conveying devices 101, if the quality signal is 0 (i.e., normal product), the glass substrate 104 to be tested may be a good product, a re-cleaned product, or a defective product; if the quality signal is 1 (i.e., a machine adjustment product), the glass substrate 104 to be tested is a defective product; if the quality signal is 2 (i.e., a re-cleaned product), the glass substrate 104 to be tested may be a good product or a defective product, thereby realizing the detection of the quality of the glass substrate. Considering that the quality requirements for glass substrates in actual production are relatively high, the same glass substrate 104 to be tested cannot be indicated as a re-cleaned product multiple times. Therefore, it is necessary to limit the number of times the glass substrate 104 to be tested is indicated as a re-cleaned product. For example, the number of times the glass substrate 104 to be tested can be indicated as a re-cleaned product can be set to 1, that is, the glass substrate 104 to be tested indicated as a re-cleaned product cannot be indicated as a re-cleaned product again after processing.

[0073] In summary, the tracking device of the quality signal in the present disclosure includes: a conveying device, a control switch and a controller, each conveying device corresponds to a control switch, and the control switch is connected to the controller. The conveying device is used to perform a corresponding processing procedure on the glass substrate to be tested when the glass substrate to be tested enters the input port of the conveying device, and after completing the processing procedure, the glass substrate to be tested is transmitted to the output port of the conveying device. The control switch is used to send a control signal to the controller, and the control signal is a signal issued by the user that can indicate the quality of the glass substrate to be tested. The controller receives the control signal, and if the control signal is received, the quality signal is determined according to the control signal. If the control signal is not received, the quality signal is determined according to the historical quality signal output by the previous conveying device, and the quality signal is output. The present disclosure can switch the quality signal output by the controller to indicate the quality of each glass substrate by sending different control signals through the control switch without interrupting the conveying device, and can realize the detection and analysis of the quality of the glass substrate, so that the conveying device and the production line can continuously process glass substrates of different qualities without causing the interruption of the production line, thereby improving the production efficiency of the glass substrate.

[0074] Figure 2 is a block diagram of another quality signal tracking device according to an exemplary embodiment. Figure 2 As shown, the device 100 further includes: a sensor 105 disposed on the conveying device 101 , and the sensor 105 is connected to the controller 103 .

[0075] The sensor 105 is used to send an entry signal to the controller 103 when it detects that the glass substrate 104 to be tested enters the input port of the conveying device 101 , and to send a departure signal to the controller 103 when it detects that the glass substrate 104 to be tested leaves the output port of the conveying device 101 .

[0076] The controller 103 is further configured to receive a control signal when receiving an entry signal.

[0077] The controller 103 is further configured to output a quality signal when receiving a leaving signal.

[0078] For example, the quality signal tracking device 100 may further include a sensor 105, which may be disposed on the conveying device 101. The number of sensors 105 disposed on the conveying device 101 may be one or more, and each sensor 105 is connected to the controller 103. The sensor 105 can detect the position of the glass substrate 104 to be tested on the conveying device 101 and send a corresponding signal to the controller 103. For example, a sensor 105 may be disposed at the input port and the output port of the conveying device 101, respectively. When the glass substrate 104 to be tested enters the input port of the conveying device 101, the sensor 105 disposed at the input port detects that the glass substrate 104 to be tested enters the conveying device 101, and may send an entry signal to the controller 103. When the glass substrate 104 to be tested leaves the output port of the conveying device 101, the sensor 105 disposed at the output port detects that the glass substrate 104 to be tested leaves the conveying device 101, and may send a departure signal to the controller 103. The entry signal and the exit signal can be represented by a rising edge signal and a falling edge signal respectively, and it can be understood that when the glass substrate 104 to be tested enters the input port of the conveying device 101, the signal sent by the sensor 105 to the controller 103 is a rising edge signal, and when the glass substrate 104 to be tested leaves the output port of the conveying device 101, the signal sent by the sensor 105 to the controller 103 is a falling edge signal. The sensor 105 can be, for example, a pressure sensor, a weighing sensor, a resistive sensor, etc. If the controller 103 receives an entry signal sent by the sensor 105, it means that the glass substrate 104 to be tested has entered the input port of the conveying device 101. At this time, the controller 103 can continue to receive the control signal sent by the user and determine the quality signal according to the control signal. If the controller 103 receives a departure signal sent by the sensor 105, it means that the glass substrate 104 to be tested has left the output port of the conveying device 101. At this time, the controller 103 can output the quality signal determined when the glass substrate 104 to be tested enters the input port of the conveying device 101 after the glass substrate 104 to be tested completes all processing procedures, so as to transmit the quality signal of the glass substrate 104 to be tested.

[0079] Optionally, the controller 103 is a programmable logic controller (PLC).

[0080] The PLC is used to store the control signal as a quality signal in the first space if a control signal is received, and store the historical quality signal as a quality signal in the first space if no control signal is received.

[0081] The PLC is also used to store the quality signal stored in the first space into the second space and output the quality signal stored in the second space when the glass substrate 104 to be tested leaves the output port of the conveying device 101 .

[0082] For example, the PLC may be provided with a first space and a second space, which correspond to different register addresses respectively and are used to store different signals. For example, the register address of the first space is D1000, and the register address of the second space is D1001. The PLC receives a control signal sent by the user through the control switch 102, indicating that the user has put a glass substrate 104 to be tested that is different in quality from the glass substrate 104 to be tested that was previously put in at the input port of the conveying device 101. At this time, it is necessary to switch the quality signal output by the device 100, so the control signal can be directly stored in the first space as a quality signal. If the PLC does not receive the control signal sent by the user, it means that the quality of the glass substrate 104 to be tested put in the input port of the conveying device 101 remains unchanged, and the user has not put in a glass substrate 104 to be tested of other qualities, then the PLC can store the historical quality signal as a quality signal in the first space. After determining the quality signal in the first space, when the glass substrate 104 to be tested leaves the output port of the conveying device 101, the quality signal stored in the first space can be transferred to the second space, and then the quality signal stored in the second space is output. The PLC may also be provided with a third space and a fourth space. The third space is used to store the control signal when the glass substrate 104 to be tested enters the previous conveying device. The fourth space is used to store the signal in the third space when the glass substrate 104 to be tested leaves the previous conveying device, i.e., the historical quality signal.

[0083] Figure 3 is a block diagram of another quality signal tracking device according to an exemplary embodiment. Figure 3 As shown, the device 100 further includes: a display terminal 106 , and the display terminal 106 is connected to the controller 103 .

[0084] The display terminal 106 is used to receive the quality signal output by the controller 103 and display the quality signal.

[0085] For example, the quality signal tracking device 100 may further include a display terminal 106, and the display terminal 106 is connected to the controller 103. After the controller 103 determines the quality signal according to the control signal sent by the user, the quality signal may be sent to the display terminal 106, so that the display terminal 106 displays the quality signal output by the controller 103. The display terminal 106 may be, for example, a mobile terminal with a display interface such as a smart phone, a tablet computer, a smart TV, a PDA (English: Personal Digital Assistant, Chinese: Personal Digital Assistant), a portable computer, or a fixed terminal such as a desktop computer. After the display terminal 106 receives the quality signal sent by the controller 103, the quality signal of the glass substrate 104 to be tested can be displayed in digital form on the display terminal 106. For example, if the quality signal displayed on the display terminal 106 is 0 (i.e., a normal product), the glass substrate 104 to be tested may be a good product, a re-cleaned product, or a waste product. Next, a technical inspector or a specific inspection device can continue to determine the quality level of the processed glass substrate 104 to be tested. If the quality signal displayed on the display terminal 106 is 1 (i.e., a machine adjustment product), the glass substrate 104 to be tested can be directly determined as a waste product. If the quality signal displayed on the display terminal 106 is 2 (i.e., a re-cleaned product), the quality level of the processed glass substrate 104 to be tested needs to be inspected by a technical inspector or a specific inspection device, as with a normal product, to determine whether the glass substrate 104 to be tested needs to be reprocessed. If it is determined that the glass substrate 104 to be tested needs to be reprocessed, the glass substrate 104 to be tested is reprocessed. The display terminal 106 may also store the received quality signal, and the technical inspector may view the signal when he needs to judge the quality level of the processed glass substrate, which is not limited in the present disclosure.

[0086] Optionally, the control signal includes: a signal designated by the user indicating that the quality of the glass substrate 104 to be tested is any one of normal product, adjusted product and re-cleaned product; the quality signal includes: a signal for indicating that the quality of the glass substrate 104 to be tested is any one of normal product, adjusted product and re-cleaned product.

[0087] For example, the control signal is specified by the user and sent through the control switch 102, which can indicate that the quality of the glass substrate 104 to be tested is any one of a normal product, a machine adjustment product, and a re-cleaned product. The quality signal is determined by the controller 103 through the control signal, which can indicate that the quality of the glass substrate 104 to be tested is any one of a normal product, a machine adjustment product, and a re-cleaned product. If the user puts a glass substrate 104 to be tested that is different in quality from the glass substrate 104 to be tested that was previously put in at the input port of the conveying device 101, then it is necessary to switch the quality signal. At this time, the user sends the specified control signal through the control switch 102. After receiving the control signal, the controller 103 can directly determine the quality signal according to the control signal, for example, directly use the control signal as the quality signal, or analyze the control signal to obtain the quality of the glass substrate 104 to be tested, and then determine the quality signal according to the quality of the glass substrate 104 to be tested. There is a one-to-one correspondence between the quality signal output by the controller 103 and the control signal sent by the user. It can be understood that if the control signal sent by the user through the control switch 102 indicates that the glass substrate 104 to be tested is a normal product when it enters the conveying device 101, then the quality signal of the glass substrate 104 to be tested determined by the controller 103 when it leaves the conveying device 101 also indicates that the glass substrate 104 to be tested is a normal product. If the user does not put in glass substrates 104 of other qualities to be tested, the control signal may not be sent to the controller 103, and the controller 103 may determine the quality signal based on the historical quality signal output by the previous conveying device.

[0088] Figure 4 is a block diagram of another quality signal tracking device according to an exemplary embodiment. Figure 4 As shown, the conveying equipment 101 is a plurality of groups of conveying equipment 101, each group of conveying equipment 101 corresponds to a control switch 102, and the plurality of groups of conveying equipment 101 are arranged in sequence according to the execution order of the processing procedures corresponding to each group of conveying equipment 101, and the input port of each group of conveying equipment 101 is connected to the output port of the previous group of conveying equipment 101 of the group of conveying equipment 101, and the output port of the group of conveying equipment 101 is connected to the input port of the next group of conveying equipment 101 of the group of conveying equipment 101.

[0089] For example, the quality signal tracking device 100 may include not only the conveying device 101, the control switch 102 and the controller 103, but also a sensor 105 and a display terminal 106. In a scenario where there are multiple groups of conveying devices 101, for example, the quality signal tracking device 100 includes 4 groups of conveying devices 101. The device 100 includes 4 control switches 102 corresponding to the 4 groups of conveying devices 101, one control switch 102 corresponding to each group of conveying devices 101, and each group of conveying devices 101 corresponds to a processing step. Each control switch 102 in the device 100 is connected to the controller 103. One or more sensors 105 may be set on each group of conveying devices 101. For example, a sensor 105 may be set at the input port and the output port of each group of conveying devices 101, and each sensor 105 is connected to the controller 103. Multiple groups of conveying equipment 101 can be connected end to end in sequence according to the execution order of the corresponding processing steps, that is, the input port of each group of conveying equipment 101 is connected to the output port of the previous group of conveying equipment 101 in the execution order, and the output port of each group of conveying equipment 101 is connected to the input port of the next group of conveying equipment 101 in the execution order.

[0090] When the glass substrate 104 to be tested is processed, the glass substrate 104 to be tested can be put into the input port of any processing process (i.e., any group of conveying devices 101). At this time, the user sends control signals to and from the control switch 102 corresponding to the group of conveying devices 101, and the control switch 102 sends the control signals to the controller 103. When the sensor 105 set at the input port of the group of conveying devices 101 detects that the glass substrate 104 to be tested enters, the controller 103 receives the control signal and determines the quality signal according to the control signal. When the sensor 105 set at the output port of the group of conveying devices 101 detects that the glass substrate 104 to be tested leaves, the controller 103 outputs the quality signal. In this way, the user only needs to press different buttons of the control switch 102 corresponding to the corresponding processing process according to the preset rules to determine the control signal, and the quality signal can be displayed through the display terminal 106 connected to the controller 103 after the glass substrate 104 to be tested has completed the remaining processing processes in sequence.

[0091] For example, if the quality signal tracking device 100 includes 4 groups of conveying devices 101, and the processing steps corresponding to each group of conveying devices 101 are scribing process, grinding process, cleaning process, and inspection process, then the 4 control switches 102 connected to the controller 103 can be, for example, control switch A, control switch B, control switch C, and control switch D, wherein the 4 control switches 102 correspond to the above 4 processing steps in sequence, that is, each of the 4 control switches 102 corresponds to each group of conveying devices 101 in sequence. When processing the glass substrate 104 to be tested, the glass substrate 104 to be tested can be put into the input port of any processing step (that is, any group of conveying devices 101). For example, a glass substrate 104 to be tested can be put into the input port of the grinding process. After the glass substrate 104 to be tested is put in, the user needs to press the control switch B corresponding to the grinding process according to the preset rule to send a control signal indicating the quality of the glass substrate 104 to be tested to the controller 103. When the sensor 105 arranged on the conveying device 101 corresponding to the grinding process detects that the glass substrate 104 to be tested is conveyed to the input port of the group of conveying devices 101, the controller 103 receives the control signal, and when the sensor 105 is detected that the glass substrate 104 to be tested is conveyed to the output port of the group of conveying devices 101, the controller 103 is instructed to output a quality signal determined by the control signal. Then, after the glass substrate 104 to be tested has successively executed the grinding process, the cleaning process, and the inspection process, the quality signal is displayed through the display terminal 106 connected to the controller 103.

[0092] In summary, the tracking device of the quality signal in the present disclosure includes: a conveying device, a control switch and a controller, each conveying device corresponds to a control switch, and the control switch is connected to the controller. The conveying device is used to perform a corresponding processing procedure on the glass substrate to be tested when the glass substrate to be tested enters the input port of the conveying device, and after completing the processing procedure, the glass substrate to be tested is transmitted to the output port of the conveying device. The control switch is used to send a control signal to the controller, and the control signal is a signal issued by the user that can indicate the quality of the glass substrate to be tested. The controller receives the control signal, and if the control signal is received, the quality signal is determined according to the control signal. If the control signal is not received, the quality signal is determined according to the historical quality signal output by the previous conveying device, and the quality signal is output. The present disclosure can switch the quality signal output by the controller to indicate the quality of each glass substrate by sending different control signals through the control switch without interrupting the conveying device, and can realize the detection and analysis of the quality of the glass substrate, so that the conveying device and the production line can continuously process glass substrates of different qualities without causing the interruption of the production line, thereby improving the production efficiency of the glass substrate.
