[ first embodiment ] A method for manufacturing a semiconductor device
Referring to fig. 1, fig. 1 is a flowchart of a lamp panel classification method according to a first embodiment of the present invention. The lamp panel classification method comprises the following steps:
step S1, acquiring a parameter detection value of the lamp panel to be graded, wherein the parameter detection value is used for representing the brightness and the chromaticity of the lamp panel to be graded; specifically, parameter detection values of the lamp panel to be graded are collected through data collection equipment such as a colorimeter or equipment with a brightness and chroma value measurement function, and the representing modes of brightness and chroma include but are not limited to brightness values and color coordinate values, or brightness values and wavelengths, or tristimulus values;
step S2, determining a brightness interval and a chromaticity interval where the parameter detection values of the lamp panel to be graded are located; specifically, the classification results corresponding to the brightness interval and the chromaticity interval are associated through a preset grading parameter table, and parameter detection values of the lamp panel to be graded are compared one by one according to the brightness interval and the chromaticity interval of the preset grading parameter table; and
step S3, obtaining the classification result of the lamp panel to be graded according to the brightness interval and the chromaticity interval; specifically, when all parameter detection values of the lamp panel to be graded are located in the luminance interval and the chrominance interval, the classification result associated with the luminance interval and the chrominance interval is used as a classification result.
In a specific embodiment, the lamp panel classification method further includes obtaining control information according to the classification result, and feeding back the control information to a loading and unloading device such as a manipulator.
In order to more clearly understand the present embodiment, the lamp panel classification method of the present embodiment is briefly described below. The lamp panel classification method provided by the embodiment of the invention is characterized in that the software is used for grading the parameter detection values of the lamp panels to be graded according to the preset grading parameter table, so that the colors of the LED lamp panels belonging to the same grading in multiple batches are uniform after the LED lamp panels are spliced into the display screen. The preset grading parameter table here may be obtained by a user (user) by operating the software to perform setting, or may be obtained by the user by operating the software to import the preset grading parameter table, which is not limited herein. The following description will be given by taking an example in which the user (user) performs setting by operating the software to obtain the preset grading parameter table.
A user sets a plurality of graded brightness intervals and chromaticity intervals of a plurality of parameter detection values according to actual needs. And collecting the parameter detection value of the lamp panel to be graded through data collection equipment such as a colorimeter or equipment with a measured brightness and chroma value. The data acquisition method can adopt the existing method, and the details are not repeated here. The parameter detection value is used for representing the brightness and the chromaticity of the lamp panel to be graded, and the brightness and the chromaticity can be represented by a combination of brightness and color coordinates (Cx, Cy), a combination of brightness and wavelength, or other parameters capable of representing chromaticity such as XYZ tristimulus values. Each of the gradations includes the corresponding luminance interval and the chrominance interval, and the gradations can be seen in table 1 and table 2.
TABLE 1 luminance and chrominance intervals with luminance and color coordinates as multiple gradations
TABLE 2 luminance and chrominance intervals in multiple gradations of luminance and wavelength
In addition, the above-mentioned lamp panel to be graded may also be a self-luminous lamp panel, and the preset grading parameter table generally includes a plurality of graded luminance intervals and chromaticity intervals of different colors, for example, one grading interval may have a luminance interval and chromaticity interval corresponding to at least 1 (monochromatic) color to 3 (RGB three colors) or may be set by adding other composite colors (white, yellow, etc.).
And after data acquisition, classifying the parameter detection values according to a preset grading parameter table to obtain a classification result. For example, the parameter detection values are compared with the corresponding luminance intervals and the corresponding chrominance intervals of the plurality of grades one by one to judge which classification result the lamp panel to be graded belongs to. And when the parameter detection values are all located in the brightness interval and the chromaticity interval corresponding to the classification result, taking the corresponding classification result as the classification result of the lamp panel to be classified. For example, the acquired parameter detection values of the lamp panel to be graded include, for example, a red brightness value of 870, a Cx of 0.693, a Cy of 0.3, a green brightness value of 1750, a Cx of 0.17, a Cy of 0.738, a blue brightness value of 280, a Cx of 0.137, and a Cy of 0.078. Comparing the parameter detection value of the lamp panel to be graded with the brightness interval and the chromaticity interval in the table 1 one by one, and determining that the classification result of the lamp panel to be graded is the first grade. Therefore, the classification result of the lamp panel to be classified is the first grade. And finally, outputting the classification result of the graded lamp panel, for example, outputting the classification result on a display screen or in other modes, so that a user can learn the classification result of the lamp panel.
Further, lamp plate classification when the LED lamp plate is completed through an automatic production line and a manipulator, data collection is carried out on the LED lamp plate by data collection equipment after the LED lamp plate is fed, a parameter detection value is obtained, then the collected parameter detection value is transmitted to software for classification, after the LED lamp plate reaches a feed opening, the software outputs a classification result, for example, the classification result is displayed through a display or is sent to corresponding equipment, and finally, the LED lamp plate is placed in a placement area corresponding to grading according to the classification result through manual work or automatic equipment, so that the classification of the LED lamp plate can be completed.
In summary, in the present embodiment, the parameter detection values of the lamp panels to be graded are graded according to the preset grading parameter table, so that the LED lamp panels in each grade can be corrected by using normal correction software, and a better display effect is achieved, thereby achieving a better display effect of multiple batches of display screens, further improving the value of multiple batches of display screens, reducing the correction difficulty of chromatic aberration of LED finished products caused by processes, and solving the problem of fatigue observation during manual observation according to the output classification result, and even outputting the LED finished products to the manipulator for mechanical classification, thereby reducing the production cost and labor intensity.
