Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are intended to be within the scope of the present application.

The embodiment of the application provides a screen scanning method, which can be applied to electronic equipment. The electronic device may be a display device such as a television.

Referring to fig. 1, fig. 1 is a schematic flow chart of a screen scanning method according to an embodiment of the present disclosure. The screen scanning method is applied to electronic equipment, and can comprise the following steps:

step 101, detecting the aspect ratio of the frame display of the target video.

In some embodiments, the aspect ratio of the target video is determined by detecting the video signal corresponding to the target video. The video signal has a signal format, which refers to a display scale format of the signal, and the common formats include 4. The target video signal format is 4. Therefore, the aspect ratio of the picture display of the target video can be determined by detecting the video signal corresponding to the target video.

In some embodiments, after detecting the aspect ratio of the frame display of the target video, the method further includes:

Wherein the default scanning start behavior is the first line of the screen, and the default scanning end behavior is the last line of the screen. The second control signal does not have a picture display aspect ratio, that is, the screen does not need to consider the picture display aspect ratio of the target video, so that the scanning starting line and the scanning ending line of the screen do not need to be determined again, and the scanning can be directly carried out according to the default scanning starting line and the default scanning ending line. Since the picture display aspect ratio of the target video at this time is equal to the screen aspect ratio, the picture of the target video can be displayed exactly on the screen, and there is no area on the screen where the picture is not displayed.

and if the image display aspect ratio of the target video is equal to the screen aspect ratio, controlling the screen to scan based on a default scanning start column and a default scanning end column through a second control signal, wherein the second control signal does not carry the image display aspect ratio.

The default scanning starting column is the first column of the screen, and the default scanning ending column is the last column of the screen. The second control signal does not have the picture display aspect ratio, namely the screen does not need to consider the picture display aspect ratio of the target video, so that the scanning start column and the scanning end column of the screen do not need to be determined again, and the scanning is directly carried out according to the default scanning start column and the default scanning end column. Since the picture display aspect ratio of the target video at this time is equal to the screen aspect ratio, the picture of the target video can be displayed exactly on the screen, and there is no area on the screen where the picture is not displayed.

And 102, comparing the aspect ratio of the picture display of the target video with the aspect ratio of the screen.

After detecting the aspect ratio of the target video, the aspect ratio of the target video needs to be compared with the aspect ratio of the target video.

Step 103, if the aspect ratio of the picture display of the target video is not matched with the aspect ratio of the screen, controlling the screen to determine a target screen picture scanning area matched with the aspect ratio of the picture display through a first control signal and scanning the target screen picture scanning area so as to display the target video in the target screen picture scanning area. Wherein the first control signal carries the picture display aspect ratio.

The aspect ratio of the picture display of the target video does not match the aspect ratio of the screen, that is, the aspect ratio of the picture display of the target video is larger or smaller than the aspect ratio of the screen. At this time, the screen needs to be controlled by the first control signal to re-determine the screen image scanning area, so that the re-determined screen image scanning area (target screen image scanning area) matches the image display aspect ratio of the target video, and then the screen is controlled to scan according to the target screen image scanning area, so that the target video is displayed in the target screen image scanning area.

The first control signal has a picture display aspect ratio, that is, the screen needs to re-determine a screen picture scanning area according to the picture display aspect ratio of the target video, and then scan according to the re-determined screen picture scanning area (target screen picture scanning area).

In some embodiments, if the aspect ratio of the target video is greater than the aspect ratio of the screen, the controlling the screen to determine a target screen image scanning area matching the aspect ratio of the screen display and scan the target screen image scanning area by the first control signal includes:

and controlling the screen to scan in the target screen picture scanning area.

For example, if the aspect ratio of the picture display of the target video is 21, and the aspect ratio of the screen is 16, then the screen is controlled by the first control signal to adjust the scanning start line and the scanning end line of the scanning area of the screen, that is, the scanning start line is changed from the original first line to the 281 th line, and the scanning end line is changed from the original last line (2160) to the 1880 th line, so as to obtain the target screen scanning area of the scanning start line and the scanning end line 1880 th line, and finally the screen is controlled to scan in the target screen scanning area. That is, a picture of 21.

If the screen specification is 3840 × 2160@60hz, the scan time per line is about:

line scan time t =1/60/2160 ≈ 7.7ns

21 (picture display aspect ratio of 21):

refresh rate (field frequency) f = 1/(1/2160/60 ≈ 2160-560)) ≈ 81Hz

That is, when the aspect ratio of the picture display of the target video is 21, if the optimal resolution is 3840 × 1600, the field frequency can be supported up to 81Hz, so that the over-frequency function can be realized without sacrificing the picture quality. Therefore, compared with the mode of scanning by inserting the black edge, the scheme can save the scanning time and further improve the refresh rate of the screen.

For another example, if the picture display aspect ratio of the target video is 32 and the screen aspect ratio is 16. That is, a screen of 32.

If the screen specification is 3840 × 2160@60hz, the screen supports about scan time per line:

line scan time t =1/60/2160 ≈ 7.7ns

The best resolution of a picture of 32 (picture display aspect ratio is 32):

the refresh rate (field frequency) of the signal at this time can be calculated by the following equation:

refresh rate (field frequency) f = 1/(1/2160/60 × (2160-1080)) =120Hz

That is, when the picture display aspect ratio of the target video is 32. Therefore, compared with the mode of scanning by inserting the black edge, the scheme can save the scanning time and further improve the refresh rate of the screen.

In some embodiments, if the aspect ratio of the picture display of the target video is smaller than the aspect ratio of the screen, the controlling the screen to determine and scan the target screen picture scanning area matching the aspect ratio of the picture display by the first control signal includes:

and controlling the screen to scan in the target screen picture scanning area.

For example, if the picture display aspect ratio of the target video is 4 and the screen aspect ratio is 16, the screen is controlled by the first control signal to adjust the scan start column and the scan end column of the scan area of the screen picture, that is, the scan start column is changed from the original first column to the 480 th column, the scan end column is changed from the original last column (3840) to the 3360 th column, so as to obtain the target screen picture scan area with the scan start column being the 480 th column and the scan end column being the 3360 th column, and finally the screen is controlled to scan in the target screen picture scan area.

In some embodiments, if the frame display aspect ratio of the target video does not match the screen aspect ratio, controlling the screen to determine a target screen frame scanning area matching the frame display aspect ratio and scan the target screen frame scanning area by using a first control signal includes:

and if the picture display aspect ratio of the target video is not matched with the screen aspect ratio, outputting a first control signal through a time sequence control module on a mainboard to control the screen to determine a target screen picture scanning area matched with the picture display aspect ratio and scan.

The electronic equipment comprises a main board, a timing controller and a timing control module, wherein the main board is provided with the timing controller, and the timing controller is used for controlling the timing of the electronic equipment. Therefore, for the electronic equipment without an independent time sequence controller, when the picture display aspect ratio of the target video is not matched with the screen aspect ratio, the time sequence control module on the mainboard outputs the first control signal to control the screen to determine the target screen picture scanning area matched with the picture display aspect ratio and scan the target screen picture scanning area.

In some embodiments, before the timing control module outputs the first control signal to control the screen to determine the target screen picture scanning area matched with the picture display aspect ratio and scan, the method further includes:

the time sequence control module converts a video signal corresponding to the target video into a low-voltage differential signal which can be identified by the screen, and generates the first control signal based on the low-voltage differential signal.

Since the screen cannot directly identify the video signal, the video signal corresponding to the target video needs to be converted into a low-voltage differential signal that can be identified by the screen through the timing control module.

In some embodiments, if the aspect ratio of the picture display of the target video does not match the aspect ratio of the screen, the controlling the screen to determine the target screen picture scanning area matching the aspect ratio of the picture display and scan the target screen picture scanning area through the first control signal further includes:

and if the image display aspect ratio of the target video is not matched with the screen aspect ratio, outputting a first control signal through a time schedule controller to control the screen to determine a target screen image scanning area matched with the image display aspect ratio and scanning.

When the image display aspect ratio of the target video is not matched with the screen aspect ratio, the screen is controlled to determine a target screen image scanning area matched with the image display aspect ratio through the first control signal output by the time sequence controller and scan.

In some embodiments, before the timing controller outputs the first control signal to control the screen to determine the target screen picture scanning area matching with the picture display aspect ratio and scan, the method further comprises:

Since the screen cannot directly recognize the video signal, the video signal corresponding to the target video needs to be converted into a low voltage differential signal that can be recognized by the screen through the timing controller.

All the above optional technical solutions may be combined arbitrarily to form optional embodiments of the present application, and are not described herein again.

In particular implementation, the present application is not limited by the execution sequence of the described steps, and some steps may be performed in other sequences or simultaneously without conflict.

Wherein the first control signal carries the picture display aspect ratio. According to the embodiment of the application, when the picture display aspect ratio of the target video to be displayed is not matched with the screen aspect ratio, the scanning area of the screen picture is determined again, namely the scanning starting line and the scanning ending line of the scanning area of the screen picture are determined again, the scanning is carried out on the scanning area of the screen picture after the determination is carried out again, and the scanning is not carried out in a mode of inserting black edges, so that the scanning time can be saved, and the refreshing rate of a screen can be improved.

The audio circuit 160 may transmit the electrical signal converted from the received audio data to the speaker 161, and convert the electrical signal into a sound signal for output by the speaker 161; on the other hand, the microphone 162 converts the collected sound signal into an electric signal, converts the electric signal into audio data after being received by the audio circuit 160, and then outputs the audio data to the processor 180 for processing, and then to the RF circuit 110 to be transmitted to, for example, another terminal, or outputs the audio data to the memory 120 for further processing.
