Detailed Description
Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. The same or similar numbered elements/components used in the drawings and the embodiments are used to represent the same or similar parts.
An embodiment of the present invention is a multi-panel display device. In this embodiment, the multi-screen display apparatus may be a handheld apparatus having multiple display screens, but is not limited thereto.
Fig. 2 is a schematic diagram of the multi-screen display apparatus in this embodiment, as shown in fig. 2. As shown in fig. 2, the multi-screen display device 2 includes a first display panel PL1, a first driving circuit DIC1, a second driving circuit DIC2, a second display panel PL2, a third driving circuit DIC3 and an application processor AP.
In this embodiment, the first display PL1 is a main display with a large display area and the second display PL2 is a sub display with a small display area, but not limited thereto. The first display PL1 and the second display PL2 can display frames simultaneously or only one of the first display PL1 and the second display PL2 can display frames according to actual requirements.
The first driving circuit DIC1 and the second driving circuit DIC2 are both coupled to the first display PL1 for driving the first display area and the second display area of the first display PL1, respectively. The third driving circuit DIC3 is coupled to the second display PL2 for driving the second display PL2.
It should be noted that the multi-panel display apparatus 2 in this embodiment only includes a single application processor AP, and the application processor AP has a first transmission port MIPI _ a and a second transmission port MIPI _ B.
The first transmission port MIPI _ a of the application processor AP is respectively coupled to the second driving circuit DIC2 corresponding to the first display PL1 and the third driving circuit DIC3 corresponding to the second display PL2. The application processor AP simultaneously transmits the first display data VID1 having the first tag and the second display data VID2 having the second tag to the second driving circuit DIC2 and the third driving circuit DIC3 through the first transmission port MIPI _ a. The first tab corresponds to the first display PL1 and the second tab corresponds to the second display PL2.
When the first display data VID1 with the first tag and the second display data VID2 with the second tag are simultaneously transmitted to the second driving circuit DIC2, the second driving circuit DIC2 receives only the first display data VID1 with the first tag for display on the corresponding first display PL1.
When the first display data VID1 with the first tag and the second display data VID2 with the second tag are simultaneously transmitted to the third driving circuit DIC3, the third driving circuit DIC3 will only receive the second display data VID2 with the second tag for display on the corresponding second display screen PL2.
The second transmission port MIPI _ B of the application processor AP is coupled to the first driving circuit DIC1 corresponding to the first display PL1. The second transfer port MIPI _ B transfers only the first display data VID1 with the first tag to the first driving circuit DIC1. When the first display data VID1 having the first tag is transmitted to the first driving circuit DIC1, the first driving circuit DIC1 receives the first display data VID1 having the first tag for display on the corresponding first display screen PL1.
Therefore, the multi-display apparatus 2 can simultaneously drive the first display screen PL1 (primary screen) and the second display screen PL2 (secondary screen) to display the screen that it should display through only a single application processor AP without additionally providing another application processor.
Another embodiment of the present invention is a multi-panel display device. FIG. 3 is a schematic view of the multi-panel display apparatus in this embodiment, as shown in FIG. 3. As shown in fig. 3, the multi-screen display apparatus 3 includes a first display panel PL1, a first driving circuit DIC1, a second driving circuit DIC2, a second display panel PL2, a third driving circuit DIC3 and an application processor AP.
In this embodiment, the first display PL1 is a main display with a large display area and the second display PL2 is a sub display with a small display area, but not limited thereto. The first display PL1 and the second display PL2 can display frames simultaneously or only one of the first display PL1 and the second display PL2 can display frames according to actual requirements.
The first driving circuit DIC1 and the second driving circuit DIC2 are both coupled to the first display PL1 for driving the first display area and the second display area of the first display PL1, respectively. The third driving circuit DIC3 is coupled to the second display PL2 for driving the second display PL2.
It should be noted that the multi-panel display apparatus 3 in this embodiment only includes a single application processor AP, and the application processor AP has a first transmission port MIPI _ a and a second transmission port MIPI _ B.
The first transmission port MIPI _ a of the application processor AP is coupled to the third driving circuit DIC3 corresponding to the second display PL2. The application processor AP transmits the second display data VID2 with the second tag to the third driving circuit DIC3 through the first transmission port MIPI _ a. The second tab corresponds to second display PL2.
When the second display data VID2 having the second label is transmitted to the third driving circuit DIC3, the third driving circuit DIC3 receives the second display data VID2 having the second label for display on the corresponding second display screen PL2.
The second transmission port MIPI _ B of the application processor AP is respectively coupled to the first driving circuit DIC1 and the second driving circuit DIC2 corresponding to the first display PL1. The application processor AP simultaneously transmits the first display data VID1 having the first tag and the first display data VID3 having the third tag to the first driving circuit DIC1 and the second driving circuit DIC2 through the second transmission port MIPI _ B. The first tab corresponds to a first display region of the first display PL1 and the third tab corresponds to a second display region of the first display PL1.
When the first display data VID1 having the first tag and the first display data VID3 having the third tag are transmitted to the first driving circuit DIC1, the first driving circuit DIC1 receives only the first display data VID1 having the first tag for display in the first display region of the corresponding first display screen PL1.
When the first display data VID1 with the first tag and the first display data VID3 with the third tag are transmitted to the second driving circuit DIC2, the second driving circuit DIC2 receives only the first display data VID3 with the third tag for display in the second display region of the corresponding first display screen PL1.
In other words, since the second port MIPI _ B simultaneously transmits the first display data VID1 with the first tag and the first display data VID3 with the third tag to the first driving circuit DIC1 and the second driving circuit DIC2, the first driving circuit DIC1 and the second driving circuit DIC2 identify the display data that they should receive according to whether the tag of the first display data VID1 is the first tag or the third tag, so that the first display area and the second display area of the first display PL1 can display correct display data.
Therefore, the multi-display apparatus 3 can simultaneously drive the first display screen PL1 (primary screen) and the second display screen PL2 (secondary screen) to display the screen that it should display through only a single application processor AP without additionally providing another application processor.
The combination of the above contents shows that: compared with the prior art, the multi-screen display device provided by the invention can simultaneously drive the main screen and the auxiliary screen to display the pictures to be displayed through only one application processor, so that the requirement of system hardware can be greatly reduced, and communication among different application processors can be avoided.
