All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
[ first embodiment ] A method for manufacturing a semiconductor device
Referring to fig. 1, a LED display control system detection method according to a first embodiment of the present invention is shown. The detection method of the LED display control system comprises the following steps:
s10, sending the target test image to be transmitted to the LED display module through the LED display control system to be tested to be displayed to obtain a display image;
s12, controlling the image acquisition device to acquire the display image to obtain an acquired image;
s14, acquiring the acquired image obtained by the image acquisition device; and
s16, comparing and analyzing the target test image and the collected image to determine whether the LED display control system to be tested is normal.
In order to facilitate understanding of the present invention, a detailed description of the LED display control system detection method of the present embodiment will be given below with reference to fig. 2.
Fig. 2 shows an LED display control system 20, which includes an upper computer 200, an LED display module 204 and an image acquisition device 206, and the upper computer 200 and the LED display module 204 are adapted to be electrically connected to an LED display control system 202 to be tested. Specifically, the upper computer 200 is, for example, a PC, the upper computer 200 is electrically connected to the LED display control system 202 to be tested and the image acquisition device 206, where the upper computer 200 is connected to the LED display control system 202 to be tested, for example, through a network cable or a video connection line, for example, a DVI line, and the upper computer 200 is connected to the image acquisition device 206 through a USB line or a network cable. The LED display module 204 is electrically connected to the LED display control system 202 to be tested through a flat cable or a connector. The LED display module 204 may be an LED lamp panel, or a plurality of LED lamp panels spliced together. The LED display control system 202 under test is, for example, a module controller such as a receiving card or, for example, a combination of a display controller such as a sending card and a module controller such as a receiving card. The image capture device 206 may be, for example, an area-array camera (e.g., a CCD camera).
In the process of executing the LED display control system detection method of this embodiment, first, the upper computer 200 (specifically, the test software on the upper computer 200) responds to the operation of the user to send the target test image to the LED display control system 202 to be tested, and the LED display control system 202 to be tested performs image processing (for example, decoding and data conversion) on the received image to be tested and then sends the image to be tested to the LED display module 204 for display so as to obtain a display image (corresponding to step S10 in fig. 1).
Thereafter, the upper computer 200 controls the image capturing device 206 to capture the display image displayed by the LED display module 204 to obtain a captured image (corresponding to step S12 in fig. 1), and acquires the captured image from the image capturing device 206 (corresponding to step S14 in fig. 1).
Then, the upper computer 200 compares and analyzes the target test image and the collected image to determine whether the LED display control system 202 to be tested is normal (corresponding to step S14 in fig. 1), that is, whether the LED display control system is good; if the product is normal, the product is good, otherwise, if the product is abnormal, the product is not good. Here, the abnormality of the LED display control system 202 under test may indicate that the LED display control system 202 under test incorrectly identifies the target test image, or may indicate that the LED display control system 202 under test receives correct image data but performs incorrect image processing when performing image processing. In the embodiment of the present invention, the specific abnormality cause of the LED display control system 202 to be tested is not located, but whether the LED display control system 202 to be tested is abnormal is determined only according to the result of image output.
In addition, it should be noted that, in the whole testing process, the LED display control system 204 to be tested does not perform scaling processing on the target test image, but directly sends the original target test image to the LED display module 204 for displaying with the same resolution.
Specifically, the above alignment analysis process (corresponding to step S14) can be implemented by the following two embodiments, one of which includes the following steps: (1) the upper computer 200 performs image processing on the display image to determine color information of the collected image and pixel points corresponding to each LED lamp point in the LED display module 204, so as to obtain display color information. Here, the color information is RGB color values, and the display color information is a set of color information of pixel points corresponding to all the light points of the display image and the LED display module 204. Here, the image processing typically includes region positioning and point positioning, which are well-established prior art and will not be described in detail herein. (2) The upper computer 200 determines color information of each pixel point of the target test image to obtain target test color information, where the target test color information is a set of color information of all pixel points of the target test image. The target test image may be a solid color image or a general color image, and is not limited in this respect. (3) The upper computer 200 compares the display color information with the target test color information one by one to determine whether the display color information is consistent with the target test color information so as to obtain a comparison result, and determines whether the to-be-tested LED display control system 202 is normal according to the comparison result. Specifically, under the condition that the comparison result is that the display color information is consistent with the target test color information, the upper computer 200 determines that the LED display control system 202 is normal. And if the comparison result is that the display color information is inconsistent with the target test color information, the upper computer 200 determines that the LED display control system 202 is abnormal. It should be noted that, in this embodiment, each pixel point in the target test image drives and controls each LED light point of the LED display module 204, and each LED light point corresponds to one pixel point in the collected image.
In another embodiment, the target test image includes, for example, a solid full bright image (e.g., a solid image such as a red full bright image, a green full bright image, a blue full bright image, and a white full bright image) and a solid line image (e.g., a solid horizontal line image, a solid vertical line image, a solid left oblique line image, and a solid right oblique line image), and the display image includes a first captured image corresponding to the solid full bright image and a second captured image corresponding to the solid line image. Here, the first captured image is an image displayed when the upper computer 200 sends the solid-color full-bright image to the LED display module 204, and the second captured image is an image displayed when the upper computer 200 sends the solid-color line image to the LED display module 204. The corresponding implementation steps are as follows: (1) the upper computer 200 compares and analyzes the pure color full bright image and the first collected image to determine a first comparison result. Specifically, taking the pure color full-bright image as a red image as an example, the process of determining the first comparison result correspondingly includes: analyzing color information, namely RGB color values, of pixel points corresponding to the first collected image and each LED lamp point of the LED display module 204 to determine whether the color information of each pixel point is matched with the color information of a red image, namely whether the first collected image is indicated to be the red image, and if the first collected image is determined to be the red image, displaying the first collected image normally according to a first comparison result. (2) The upper computer 200 compares and analyzes the pure color line image and the second collected image to obtain a second comparison result. Specifically, taking the pure-color line image as a red left-oblique line image as an example, the process of determining the second comparison result is as follows: and judging whether the LED lamp points which should be lightened in the LED display module 204 are lightened according to the red left oblique line image and the second collected image so as to obtain a second comparison result. For example, the LED lamp point on the LED display module 204 that should be turned on can be determined according to the red left oblique line image, and it can be determined whether the LED lamp point currently turned on by the LED display module 204 is the LED lamp point that should be turned on by combining the second collected image, when the lamp turning-on condition is correct, the second comparison result is that the second collected image is displayed normally, and when the lamp turning-on condition is wrong, the second comparison result is that the second collected image is displayed abnormally. (3) And the upper computer 200 determines whether the display control system is normal according to the first comparison result and the second comparison result. Specifically, when both the first captured image and the second captured image are displayed normally, it is indicated that the display control system is normal, and when at least one of the first captured image and the second captured image is displayed abnormally, it is indicated that the display control system is abnormal. It should be noted that, it may also be determined whether the displayed image has problems of screen blooming, misalignment, black screen, and color cast in other manners, so as to determine whether the LED display control system 202 to be tested is normal according to the determination result, which is not specifically described herein.
In summary, in the scheme of this embodiment, whether the LED display control system to be tested is normal is determined by comparing and analyzing the target test image with the collected image obtained by actually displaying the display image on the LED display module through the LED display control system to be tested, which is collected by the image collection device, so that the test automation is realized, the detection efficiency and the accuracy are improved, human-eye observation is not needed, the quality of the test result is improved, the missing inspection caused by personal reasons is avoided, and the missing inspection rate is reduced.
