Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The display device produced by a manufacturer needs to face many customers, and each customer may have different customer systems, and there are differences between different customer systems. In the case of not adapting to another customer's system, it is easy to cause loss of customers due to the low adaptability of the existing display device.

The display processing method, display panel and display device provided in this embodiment can improve the display effect of the image and enhance the adaptability between the display device and different signal sources when the original image data provided by the signal source is abnormal.

An embodiment of the present invention provides a display processing method, which is applied to a display panel. As shown in FIG. 1 , the method includes:

Step 101: After receiving the original image data sent by the signal source, trigger a detection operation on the original image data.

Step 102: when it is detected that the original image data is abnormal, adjust the phase parameter of the original image data from an initial value to a target value;

Step 103 : Transmit the adjusted actual image data to the driving circuit of the display panel, wherein the picture noise when displayed according to the actual image data is smaller than the picture noise when displayed according to the original image data.

In the embodiment of the present invention, the actual image data is obtained by detecting the original image data sent by the signal source, and adjusting the phase parameter of the original image data to the target value in the case of detecting that the original image data is abnormal, and converting the actual image data It is transmitted to the driving circuit, so that the noise of the picture displayed by the display panel is reduced, the display effect is improved, and the adaptability of the display panel to different signal sources can also be enhanced. Therefore, the technical solution provided by the present invention can improve the display effect of the display panel when the original image data is abnormal, and enhance the adaptability of the display panel to different signal sources.

After receiving the original image data provided by the signal source, the receiving end of the above-mentioned display panel needs to convert the original image data into actual image data that can drive the display panel to display, but the signal quality of the original image data provided by the unsuitable signal source Poor and poor signal shielding will cause the display panel to appear noise when displaying high-frequency images.

As shown in Figure 2, under normal circumstances (that is, no abnormality in the original image signal is detected), after the display panel receives the original image signal sent by the signal source, it goes through the picture detection function (PDF) module, dynamic color temperature correction (ACC) A series of modules such as module, dither module and spread spectrum (SSCG) module are processed for image quality, and then the processed image signal is sent to the drive circuit of the display panel through the output terminal.

In the embodiment of the present invention, the display panel adds the functions of detecting the original image data and adjusting the phase. A specific detection method may be to detect whether the eye diagram of the original image signal has more clutter. The eye diagram shown in FIG. 3a indicates more clutter, and the eye diagram shown in FIG. 3b has less clutter.

When it is detected that the original image signal is abnormal, the phase parameter of the original image data is additionally adjusted from the initial value to the target value on the basis of the above image quality processing, that is, the relative position of the original image data and the clock is adjusted, to a certain extent Improve the quality of the signal and improve the display effect of image data on the display panel.

It should be noted that the abnormality in the original image data includes the absence of part of the original image data, the phase change of the original image data caused by electromagnetic interference, and the like.

The specific adjustment process of the phase parameters is shown in Figure 4. After phase adjustment, A in the original image data is A' in the actual image data, and B in the original image data is B' in the actual image data after phase adjustment.

In an optional embodiment, before the step of detecting that the original image data is abnormal, the method further includes:

Use preset test conditions to detect the original image data;

If image noise is detected in the original image data during the detection process, and an abnormal result is obtained after comparing the original image data with preset normal data and preset abnormal data by using a comparison circuit, the original image data is determined to be the original image. There is an abnormality in the image data.

In this embodiment, test conditions for detecting the original image data are preset, and using the test conditions to detect the original image data can clearly find out whether there is image noise in the subsequent display of the original image data, for example: the test condition is gray The test images with different tone transitions are set in the level conversion area, as shown in Figure 5, so that if the original image data is abnormal at high frequency, image noise will easily appear in the test image because the data conversion is too fast.

The test sequence for detection using the preset test conditions may be to scan in the direction from the output end to the receiving end, that is, to detect the original image data between the SSCG module and the output end, and then to detect the original image data between the Dither module and the SSCG module. Detect the original image data between the ACC module and the Dither module, then detect the original image data between the PDF module and the ACC module, and finally detect the original image data between the receiving end and the PDF module. Such a detection sequence can not only detect whether the original image data is abnormal, but also can detect whether each image quality processing module is abnormal. For example: when the detection result of the original image data between the ACC module and the Dither module is abnormal, but the detection result of the original image data between the PDF module and the ACC module is not abnormal, it can be determined that the abnormality of the ACC module leads to abnormal image quality processing. The resulting raw image data is abnormal. If the original image data between the detection receiving end and the PDF module is detected, it is determined that the abnormal cause of the original image data is caused by the adaptation of the signal source and the display panel.

In addition, a comparison circuit is added to the display panel, as shown in FIG. 6 , the comparison circuit has tested normal image data and abnormal image data in advance, and stored their respective characteristic parameters. When the comparison circuit tests the abnormal original image data, it will obtain a result similar to or the same as the abnormal image data, so as to output a low level as the abnormal result; when the comparison circuit tests the normal original image data, it will obtain the same result as the normal image. data are similar or the same result, thus outputting a high level as a normal result

In this embodiment, when image noise is detected in the process of detecting the original image data using the preset test conditions, and the comparison circuit obtains an abnormal result, it is determined that the original image data is abnormal. In this way, it is possible to determine whether there is an abnormality in the original image data, and also to determine the cause of the abnormality. In the case of the abnormality caused by the image quality module, the image quality module can be replaced in time to avoid unnecessary phase adjustment.

In another optional embodiment, the step of adjusting the phase parameter of the original image data from an initial value to a target value includes:

Determine the adjustment range of the phase parameter of the original image data according to the phase parameter and the amplitude parameter of the original image data;

The phase parameter of the original image data is increased from an initial value by a preset value and then adjusted to a target value, where the preset value is within the adjustment range.

In this embodiment, the adjustment range of the phase parameter of the original image data is determined based on the phase parameter and the amplitude parameter of the original image data in combination with a table look-up method. As shown in FIG. 7 , the amplitude (Swing) and the skew (Skew) of the original image data correspond to 1, 2, 3 and 4 gears. Different gears correspond to the clock frequencies of different original image data, and Fclk is used as a reference for comparison. By determining the phase parameter and amplitude parameter of the original image data, after determining the gear, the adjustment range of the phase parameter of the original image data can be obtained.

Since excessive adjustment of the phase will also cause bad effects of electromagnetic interference (EMI), the display effect of the display panel will not be improved. In this embodiment, the phase parameter of the original image data is determined according to the phase parameter and the amplitude parameter of the original image data. The adjustment range can avoid the situation of poor EMI caused by excessive adjustment of the phase, and ensure the display effect of the display panel.

In another optional embodiment, the step of triggering a detection operation on the original image data after receiving the original image data sent by the signal source includes:

Trigger the detection operation on the original image data after receiving the original image data sent by the signal source for the first time;

After the step of transmitting the adjusted actual image data to the drive circuit of the display panel after adjusting the phase parameter of the original image data from the initial value to the target value, the step includes:

save the target value;

After receiving the original image data sent by the signal source again, the phase parameter of the image data is adjusted to the target value, and the adjusted actual image data is transmitted to the drive circuit of the display panel.

That is, it needs to be detected when the original image data sent by the signal source is received for the first time, and the phase parameter target value of the actual image data is saved after adjusting the phase of the original image data when the original image data is abnormal. This target value can make the display panel adapt to the signal source, so when the signal source is received again after that, there is no need to detect the original image data, and the phase of the original image data sent by the signal source is directly adjusted. to the target value.

In this embodiment, after the original image data of the signal source is received for the first time, there is no need to perform further detection when the original image data of the signal source is received again, and the phase parameter of the original image data can be directly adjusted to the phase value that is considered to be suitable for the signal source. Therefore, the time for detecting the original image data each time is saved, the adaptability of the display panel to the signal source is also improved, and the display effect of the display panel for displaying the original image data sent by the signal source is improved.
