Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

Referring to fig. 1, a display device according to a first embodiment of the present invention is shown, where the display device includes a driving chip 10, a processing module 20, and a display screen 30, the driving chip 10 is respectively interfaced with the processing module 20 through a first path 01, a second path 02, and a third path 03, the processing module 20 is connected with the display screen 30, and optionally, the processing module 20 and the display screen 30 may be interfaced.
The driving chip 10 is configured to generate an on-screen menu image signal and transmit the on-screen menu image signal to the processing module 20 through the first path 01 when receiving a display instruction of an on-screen menu, and read signal initial data from the processing module 20 through the second path 02 when receiving an interrupt signal transmitted by the processing module 20, generate signal prompt data according to the signal initial data, and transmit the signal prompt data to the processing module 20 through the third path 03.
And the processing module 20 is configured to send the on-screen menu image signal to the display screen 30, send an interrupt signal to the driver chip 10 through the second path 02 when detecting that the target attribute of the picture input signal changes, generate a pop-up window image signal according to the signal prompt data when receiving the signal prompt data sent by the driver chip 10, and send the pop-up window image signal to the display screen 30.
And a display screen 30 configured to display an on-screen menu according to the on-screen menu image signal and to display a pop-up window according to the pop-up window image signal.
The user can control the display device through the remote controller, the terminal and other devices, so as to call the screen menu for display, and the driving chip 10 in the display device can receive the display instruction of the screen menu issued by the user, so as to generate the screen menu image signal, that is, the screen menu is drawn through the driving chip 10. Then, the driver chip may send the on-screen menu image signal to the processing module 20 through the first path 01, that is, the data writing operation on the on-screen menu may be implemented through the first path 01. Wherein the first path 01 is used for transmitting image signals. The processing module 20 can forward the on-screen menu image signal to the display screen 30 after receiving the on-screen menu image signal through the first path 01, so that the display screen 30 can display the on-screen menu according to the on-screen menu image signal, and a user can view the on-screen menu displayed by the display device.
In practical applications, the on-screen menu may be generally used to display screen configuration information, such as color temperature (colorectp.), contrast (contrast), brightness (brightness), chroma (chroma), brightness (tint), color gamut (displaygamut), gamma value of a display, gamma value of an image, and the like. When the user wants to check or modify the picture configuration information, the user can call an on-screen menu for displaying through a remote controller, a terminal and the like matched with the display device.
In addition, the picture input signal for displaying the picture may be accessed to the processing module 20 in the display device, and when detecting that the target attribute of the picture input signal changes, the processing module 20 may send an interrupt signal to the driving chip 10 through the second path 02, where the interrupt signal may be used to trigger the driving chip 10 to read signal initial data required for displaying the popup window from the processing module 20 through the second path 02. In practical applications, the target attribute may be set according to content to be displayed by the pop-up window, for example, if the pop-up window displays the switched signal source only when the signal source is switched, the target attribute may be set as the signal source, that is, when the signal source of the target attribute changes, the processing module 20 may send the interrupt signal to the driving chip 10, and when the signal source does not change, but the image resolution corresponding to the image input signal changes, the processing module 20 may not send the interrupt signal to the driving chip 10, because the image resolution corresponding to the image input signal is not the set target attribute.

In a specific application, the signal initial data may be represented by values of the relevant registers in the processing module 20, that is, the representation form of the signal initial data may be binary register values, so that after the driver chip 10 reads the signal initial data, signal meanings corresponding to binary values of the signal initial data may be determined by querying the local database, and the signal meanings are display contents required by the pop-up window, that is, signal prompt data. Then, the driving chip 10 may transmit the signal prompt data to the processing module 20 through the third path 03.

Then, when the processing module 20 receives the signal prompt data sent by the driving chip 10, the processing module 20 may generate a pop-up window image signal according to the signal prompt data, that is, a pop-up window image is drawn according to display content required by the pop-up window, in the embodiment of the present invention, the pop-up window image is drawn by the processing module 20, then, the processing module 20 may send the pop-up window image signal to the display screen 30, so that the display screen 30 may display the pop-up window according to the pop-up window image signal, and a user may simultaneously view the pop-up window a and a screen menu B displayed by the display screen 30, as shown in fig. 2, the remaining display area of the display screen 30 may display a picture C, such as a monitoring picture, etc. it should be noted that a target attribute after the picture input signal is changed is displayed in the pop-up window a, for example, referring to fig. 2, when a signal source of the picture input signal is switched to an SQD (square division) -8K signal, and the resolution is switched to 80 854383, SQD-8K information of "resolution: 7684" SQD-8K "and" 4384.
In the embodiment of the present invention, the driving chip 10 may generate an on-screen menu image signal and send the on-screen menu image signal to the processing module 20 through the first path 01, that is, the data writing operation on the on-screen menu may be implemented through the first path 01. In addition, the driving chip 10 may read signal initial data required for displaying the popup from the processing module 20 through the second path 02 when receiving the interrupt signal sent by the processing module 20, that is, the read data operation on the popup may be implemented through the second path 01. In the embodiment of the present invention, the data writing operation on the screen menu and the data reading operation on the popup can be implemented through different transmission paths between the driver chip 10 and the processing module 20, so that the data writing operation on the screen menu and the data reading operation on the popup can be performed simultaneously, and the screen menu and the popup can be displayed simultaneously.
In addition, in the embodiment of the present invention, because the display device can simultaneously perform data reading and writing by using two transmission paths, the display device can also solve the problem of low data reading and writing efficiency caused by using one i2c interface in the prior art, that is, the data reading and writing efficiency of the display device is improved.
Furthermore, in the embodiment of the present invention, when receiving the interrupt signal sent by the processing module, the driving chip may read the signal initial data required for displaying the popup window from the processing module through the second path, so that the driving chip 10 does not need to continuously read the signal initial data required for displaying the popup window through a timer, and therefore, the display device may further solve the problem of large system resource consumption caused by reading data in a timing query manner in the prior art, that is, reduce the system resource consumption of the display device.

In practical applications, signal systems, transmission protocols and the like corresponding to different input interfaces are usually different, so that a picture input signal of a certain system can only be transmitted through the input interface corresponding to the system, and when a signal source of the picture input signal is switched, the picture input signal is switched to other input interfaces for access. The input interface may include an SDI (serial digital interface), an HDMI (high definition multimedia interface), and the like, which is not specifically limited in this embodiment of the present invention.
