Abstract
Description
Technical Field
[0001] The present invention relates to the field of display technology, and in particular to a voltage verification method, system, electronic equipment and storage medium for a glass panel. Background Art
[0002] At present, due to the process and manufacturing problems of the glass panel, picture quality problems such as crosstalk, flicker, water ripples and Mura may occur when displaying the picture. These problems usually do not exist at the same time, but once they occur, targeted improvements are required. In order to save costs, most small-size glass panels of 32 to 50 inches omit the "Demura" process at the factory. Therefore, there will be no storage IC on these glass panels to place Demura data, resulting in Mura phenomena such as uneven brightness and color. The Mura phenomenon is usually optimized by adjusting the P-Gamma voltage to achieve the "Demura" effect. However, since there are differences between the same model of glass, the voltage value optimized for "A glass" may not be applicable to "B glass", which requires individual adjustment for each piece of glass.
[0003] In related technologies, when adjusting the voltage of the glass panel piece by piece, it is necessary to adjust the Mura phenomenon to the best under a specific screen display. At this time, the voltage may need to be fine-tuned up and down. After the online modification is completed, the value is written into the memory unit of the P-Gamma module to complete the Demura process. However, due to the instability of the machine in the factory assembly line operation, the written content may be disturbed and there may be miswriting. Summary of the invention
[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a glass panel voltage verification method, system, electronic device and storage medium, which can check the content written by the machine to prevent miswriting.

[0026] The embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.
[0027] It should be understood that although the terms "first", "second", "third", etc. may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of this application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.
[0028] Unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, or a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0029] In related technologies, when adjusting the voltage of the glass panel piece by piece, it is necessary to adjust the Mura phenomenon to the best under a specific screen display. At this time, the voltage may need to be fine-tuned up and down. After the online modification is completed, the value is written into the memory unit of the P-Gamma module to complete the Demura process. However, due to the instability of the machine in the factory assembly line operation, the written content may be disturbed and there may be miswriting.
[0030] In view of the above problems, the embodiments of the present application provide a voltage verification method, system, electronic device and storage medium for a glass panel, which can verify the content written by a machine to prevent miswriting.
[0031] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.
[0032] Figure 1 It is a flow chart of a voltage verification method for a glass panel shown in an embodiment of the present application.
[0033] See also Figure 1 , a voltage verification method for a glass panel, comprising:
[0034] Step S101, accepting a voltage value to be adjusted, calculating and processing the voltage value to be adjusted and a preset voltage value table, and outputting a first pre-processed voltage value table.
[0035] It should be noted that, according to the display situation of the display screen, it is determined whether the display problem is caused by crosstalk, flicker, water ripples or Mura, and the voltage value to be adjusted is obtained. Then the voltage value to be adjusted is calculated and processed with the preset voltage value table. Among them, the preset voltage value table is the voltage value table that comes with the P-Gamma IC. Not all voltages will be adjusted for Mura voltage regulation. Generally speaking, only some voltage values will be adjusted. Therefore, there are generally only a few voltage values to be adjusted, and then the voltage value to be adjusted will be merged and replaced with the preset voltage value table to obtain the first pre-processed voltage value table. The first pre-processed voltage value table here can be understood as a standard voltage value table.
[0036] Step S102, writing the voltage value to be adjusted into a second pre-processed voltage value table.
[0037] It should be noted that the second pre-processing voltage value table here may have the risk of being written incorrectly, thereby causing slight display abnormality on the display screen.
[0038] Step S103: determine whether the first preprocessing voltage value table is the same as the second preprocessing voltage value table. If not, generate and display abnormal voltage values, display the abnormal voltage values, and output an abnormal screen.
[0039] It should be noted that by comparing the first pre-processing voltage value table with the second pre-processing voltage value table, it is possible to accurately find out which Gramma voltage mis-write anomaly causes the Mura phenomenon. However, based on the judgment result, an abnormal voltage value is generated and displayed, and the abnormal voltage value is executed, so that the display screen displays a specific picture to remind the operator that the glass panel has a mis-write situation and needs to be removed and repaired.
[0040] Figure 2 for Figure 1 In a more detailed embodiment, a voltage verification method for a glass panel includes:
[0041] Step S201, according to the voltage value to be adjusted, obtain the voltage position to be replaced in the preset voltage value table; replace the voltage value to be adjusted according to the voltage value corresponding to the voltage position to be replaced, and output a first preprocessing voltage value table.
[0042] It should be noted that not all voltages will be adjusted for Mura voltage regulation. Generally speaking, only some voltage values will be adjusted. Therefore, based on the voltage value to be adjusted obtained by manual calculation, the voltage position to be replaced in the preset voltage value table is obtained. The voltage position to be replaced here refers to the voltage position that needs to be replaced with the voltage value to be adjusted, and there is a preset voltage value on the voltage position to be replaced. Further, the voltage value to be adjusted is replaced according to the voltage value corresponding to the voltage position to be replaced to obtain the first pre-processed voltage value table.
[0043] Step S202, writing the voltage value to be adjusted into the memory unit of the register, and outputting a second pre-processed voltage value table.
[0044] It should be noted that, for the convenience of storage, the voltage value to be adjusted will be written into the memory unit of the register.
[0045] Step S203, read the second preprocessing voltage value table of the memory unit of the register, judge the first preprocessing voltage value table and the second preprocessing voltage value table multiple times, if they are different, generate and display abnormal voltage values, execute the display abnormal voltage values, and output an abnormal screen.
[0046] It should be noted that in order to ensure the accuracy of the calibration, this step will be judged three times. If they are all different, an abnormal voltage value will be generated and displayed to output an abnormal screen to remind the operator.
[0047] Corresponding to the aforementioned application function realization method embodiment, the present application also provides a glass panel voltage verification system, an electronic device and corresponding embodiments.
