[ first embodiment ] A method for manufacturing a semiconductor device
In the existing display control equipment, when a user plays a video source sent by an upper computer such as a PC or a front-end video processor, a problem that a display screen cannot display a 3D effect may occur, which mainly includes two possibilities, that is, a normal display control equipment, but an input video source is problematic due to improper setting of the upper computer or other abnormal situations, so that the problematic video source cannot be displayed as a normal 3D display picture even if the display control equipment is normal; on the other hand, the video source sent by the upper computer is normal, but the display control device is abnormal, so that the normal video source cannot be correctly processed, and the normal 3D display screen cannot be displayed. However, when such a problem occurs, it is difficult for the user to determine which of the above-mentioned cases causes the failure, and it is also very inconvenient for the technician to troubleshoot the failure. Therefore, in order to improve human efficiency and reduce the range of troubleshooting problems to quickly troubleshoot a fault location, a first embodiment of the present invention provides a 3D screen display testing method, as shown in fig. 1, where the 3D screen display testing method includes:
step S1: responding to user operation to obtain a test signal;
step S3: acquiring a local 3D test picture according to the test signal;
step S5: and processing and outputting the 3D test picture for testing the display accuracy of the 3D picture based on human vision.
The 3D image display test method is implemented in a display control device, for example, the display control device includes a normal mode and a test mode, the display control device processes a video source sent by an upper computer normally to control an LED display screen to display a video source image in the normal mode, and the 3D image display test method provided in this embodiment is implemented in the test mode. The test signal in step S1 is generated, for example, after the user operates a test mode switch on the display control device, where the test mode switch may be a mechanical button or a touch screen switch. Specifically, for example, each time the user presses the test mode switch, the user outputs a test signal, and after acquiring the test signal, the display control device switches from the normal mode to the test mode, for example.
In one embodiment, step S3 is preceded by, for example:
step S2: and generating the 3D test picture according to preset picture parameters.
The step S2 may be, for example, after the step S1, to regenerate the 3D test screen according to the reception of the test signal. Alternatively, before step S1, for example, after the display control device is powered on or enters the 3D mode, a 3D test screen may be generated first, regardless of whether the test mode is the test mode, and then, for example, a buffer memory or the like may be further performed, so that the 3D test screen may be directly acquired when necessary. As shown in fig. 2, which is a flowchart illustrating a 3D screen display testing method according to another embodiment of the present invention, step S2 is performed between step S1 and step S3 based on the 3D screen display testing method shown in fig. 1. The preset picture parameters include, for example, resolution, frame rate, mode information, picture start coordinates, and picture pattern information of the 3D test picture, for example, the resolution is 1920 × 1080, which means that the Width (Width) of the 3D test picture is 1920 and the Height (Height) is 1080. For example, a frame rate of 60Hz means that 60 frames of images are produced per second. The mode information corresponds to a video mode of the 3D test picture, the video mode is selected from a left-right mode, an up-down mode or a continuous frame mode, wherein the video mode refers to a storage mode of the 3D image, for example, the width of a picture finally displayed in the left-right mode (Side by Side) is half of the original width, for example, the resolution is 1920 x 1080, the width of the picture finally displayed is 960, the height is 1080, and a left half picture corresponding to a left eye and a right half picture corresponding to a right eye are sequentially played; for example, the Top-and-bottom mode (Top-and-bottom) finally displays a 3D picture with a resolution of 960 × 1080 and a width of 960 and a height of 540, and the Top half picture corresponding to the left eye and the bottom half picture corresponding to the right eye are sequentially displayed; the final display width and height of the continuous frame mode are not changed, and the adjacent two frames are played alternately corresponding to the left eye and the right eye. The picture pattern information corresponds to the mode information and includes left and right pattern information, top and bottom pattern information, and adjacent frame pattern information, the picture pattern information is used to indicate the pattern displayed in a specific area of the picture (or the content to be displayed by each pixel), such as a pure color pattern or a gray scale, a diagonal, a square, and a 3D picture pattern, for example, the left half picture is displayed as pure red, and the right half picture is displayed as pure blue, and the picture pattern information may be stored in the form of, for example, an RGB value of each pixel. For example, in the preset frame parameters of a certain 3D test frame, if the video information corresponds to the left-right mode, the frame pattern information includes left-right pattern information (e.g., left red, right blue, pure color); the video information corresponds to the up-down mode, and the picture pattern information includes up-down pattern information (e.g., red, blue, and pure color); the video information corresponds to a continuous frame mode, and the picture pattern information includes adjacent frame pattern information (e.g., adjacent frames alternating red and blue, pure color). Of course, the contents included in the pattern information are expressed in text form for easier understanding, and are not to be construed as limiting the understanding of the present embodiment.
In the following, the relationship between the preset parameters of the frame and the generated 3D test frame is still illustrated in a text form, for example, the preset parameter a corresponding to a certain 3D test frame a is represented as:
a: [ resolution: 1920 × 1080, frame rate: 60Hz, mode information: left-right mode, left-eye start coordinates: (0, 0), right eye start coordinate: (960, 0), picture pattern information: left dark gray and right light gray, pure color) ]
Referring to fig. 3, which is a schematic diagram of a 3D test frame a, according to the preset frame parameters, a process of generating the 3D test frame a is as follows: after the final display, the image viewed through the 3D glasses is a dark gray area with the left side 960 × 1080 and an image viewed through the right eye is a light gray area with the right side 960 × 1080. It should be noted that, after the 3D test picture is generated according to the preset picture parameters, the 3D test picture itself contains the data content of the parameters, and the parameters can still be stored and read in the subsequent processing process.
In an embodiment, the 3D screen display testing method further includes, for example, that the preset screen parameters are not limited by video source parameters sent by the upper computer, and may be, for example, that the display control device is self-contained in a factory, or may be selected or set by a user according to actual requirements, and for example:
step S4: and responding to the parameter input operation of the user to acquire the preset picture parameters.
Step S4 may be performed, for example, at any position before step S2, and after step S4, for example, buffering may be performed. Referring to fig. 2, step S4 is performed before step S1, for example.
Alternatively, in another embodiment, step S2 further includes, for example:
step S21: and selecting target picture parameters from multiple groups of preset picture parameters according to the parameter selection control signal to generate a target 3D test picture. For example, the plurality of sets of preset frame parameters include:
b: resolution 1920 × 1080, frame rate 60HZ, mode information: left-right mode, left-eye start coordinates: (0, 0), right eye start coordinate: (960, 0), picture pattern information: left red right blue, solid ];
c: resolution 1080 × 1920, frame rate 60HZ, mode information: up-down mode, left eye start coordinates: (0, 0), right eye start coordinate: (0, 960), picture pattern information: red top and yellow bottom, pure color ].
The parameter selection control signal is generated, for example, by a user operating a selection key of a display control device, the control device is provided with, for example, a "test B" button and a "test C" button, the user presses "test B" to select B as a target screen parameter to generate a left-right mode 3D test screen B corresponding to the group B, and presses "test C" to select C as a target screen parameter to generate a top-bottom mode 3D test screen C corresponding to the group C, or, for example, the "test B" and the "test C" adopt a "test B/C" switch button for switching between the two, which is not limited in a specific form in this embodiment, or, for example, more keys such as "test D" may correspond to more different groups of preset screen parameters, and also not limited in specific contents of a plurality of groups of different preset screen parameters, the two different groups of preset picture parameters may only be different in mode information, only different in frame frequency, only different in picture pattern information, or different in multiple parameters, which is not limited in this embodiment.
In one embodiment, referring to fig. 2, step S5 further includes, for example:
step S51: processing and outputting the 3D test picture to a display screen for display;
step S53: outputting a frame synchronization signal corresponding to the 3D test picture to a 3D transmitter, controlling the action of 3D glasses by the 3D transmitter, so that the picture effect when the display screen displays the 3D test picture is watched based on human vision, and judging the correctness of the 3D picture display according to the picture effect.
Wherein, the step S51 is executed for example synchronously with the step S53, the 3D emitter is used for controlling the 3D glasses (shutter type) to work, and the frame synchronization signal is used for realizing the synchronization effect of the 3D glasses and the display picture, for example, the left eye of the 3D glasses is opened while the left eye picture is displayed, the right eye is closed, the right eye of the 3D glasses is opened while the right eye picture is displayed, the left eye is closed, and the 3D effect is generated by using the visual illusion of the left and right eyes.
The following describes the principle of the 3D screen display testing method provided in this embodiment in detail:
in a normal working state, the display control device receives a video source sent by an upper computer, for example, decodes the video source, then performs 3D display processing according to a video mode, for example, a left-right mode, and outputs a 3D image to a receiving card after the processing so as to control a display screen to display a 3D image. The user can see the 3D effect through 3D glasses (which can be polarized or shutter type). When the 3D effect cannot be seen, the user presses the test mode switch, the display screen control device generates a test signal, and executes the above steps S1, S3, and S5, where the picture patterns of the 3D test picture are, for example, red for the left eye and blue for the right eye (the user can obtain this information through the setting item of the display control device), when the display screen displays the 3D image after the 3D test picture processing, the user observes the display effect through 3D glasses, covers the right eye, the picture observed by the left eye is red, covers the left eye, the picture observed by the right eye is blue, the picture observed by both eyes is purple, it indicates that the 3D test picture is normally displayed, it is determined that the display control device can normally control the display screen to display the 3D picture, the cause of failure comes from the upper computer, and the technician mainly checks the upper computer. If the 3D display effect cannot be observed, the display control device is indicated to have a fault, and the display control device needs to be checked. However, it should be noted that if the colors observed by the left and right eyes are opposite and cannot be regarded as "no 3D effect", the test may be performed again after adjusting the left and right eyes to be not opposite.
The above example is a case where the video mode of the video source is the same as the video mode of the 3D test picture, further, for example, the video of the video source is switched to the up-down mode, at this time, if the test is still performed according to the 3D test picture of the left-right mode, if the 3D test picture can normally display the 3D effect, it cannot be determined that the fault is necessarily the fault of the upper computer, it may be that the display screen control device can normally process the left-right mode but cannot normally process the up-down mode, at this time, for example, the user may modify the test parameters to adjust the video mode of the 3D test picture to the up-down mode, if the 3D effect can be normally displayed, the display control device is normal, and it is determined that the fault of the upper computer.
Or after the user starts the display control equipment, the user can directly enter the test mode to test the 3D test pictures with the video modes of the left-right mode, the up-down mode and the continuous frame mode one by one, and the three types of the test pictures can be accessed to the upper computer to control and display the video source sent by the upper computer when the three types of the test pictures can be normally displayed.
Of course, the above is only an example of a process of manually determining the display effect of the 3D test picture by the user, and the determination of the display effect of the 3D test picture may also be completed by an intelligent device having an image capturing and recognizing function instead of manually, which is not limited in this embodiment.
The embodiment processes and outputs the local 3D test picture to test the correctness of the 3D picture display based on human eye vision, judges whether the display effect of the 3D test picture is normal or not based on human eyes to judge whether the display control equipment can normally process the 3D picture or not, and the 3D test picture is the local test picture and is not influenced by an upper computer, so that the upper computer and the display control equipment can be decoupled, the fault position can be conveniently and quickly checked, and the human efficiency is improved.
