Description

The application processor AP simultaneously transmits the first display data VID1 with the first label and the first display data VID3 with the third label to the first driving circuit DIC1 and the second driving circuit DIC2 through the second transmission port MIPI_B. The first label corresponds to the first display area of the first display screen PL1 and the third label corresponds to the second display area of the first display screen PL1.

當具有第一標籤的第一顯示資料VID1及具有第三標籤的第一顯示資料VID3被傳送至第一驅動電路DIC1時，第一驅動電路DIC1僅會接收具有第一標籤的第一顯示資料VID1，以供相對應的第一顯示屏PL1的第一顯示區域顯示之。 When the first display data VID1 with the first label and the first display data VID3 with the third label are sent to the first driving circuit DIC1, the first driving circuit DIC1 will only receive the first display data VID1 with the first label , so as to be displayed in the first display area of the corresponding first display screen PL1.

當具有第一標籤的第一顯示資料VID1及具有第三標籤的第一顯示資料VID3被傳送至第二驅動電路DIC2時，第二驅動電路DIC2僅會接收具有第三標籤的第一顯示資料VID3，以供相對應的第一顯示屏PL1的第二顯示區域顯示之。 When the first display data VID1 with the first label and the first display data VID3 with the third label are sent to the second driving circuit DIC2, the second driving circuit DIC2 will only receive the first display data VID3 with the third label , so as to be displayed in the second display area of the corresponding first display screen PL1.

換言之，由於第二傳輸埠MIPI_B同時傳送具有第一標籤的第一顯示資料VID1及具有第三標籤的第一顯示資料VID3至第一驅動電路DIC1及第二驅動電路DIC2，因此，第一驅動電路DIC1係根據第一標籤來辨別其應接收的具有第一標籤的第一顯示資料VID1且第二驅動電路DIC2係根據第三標籤來辨別其應接收的具有第三標籤的第一顯示資料VID3，使得第一顯示屏PL1的第一顯示區域及第二顯示區域能顯示正確的顯示資料。 In other words, since the second transmission port MIPI_B simultaneously transmits the first display data VID1 with the first label and the first display data VID3 with the third label to the first driving circuit DIC1 and the second driving circuit DIC2, the first driving circuit DIC1 identifies the first display data VID1 with the first label that it should receive according to the first label, and the second drive circuit DIC2 identifies the first display data VID3 that it should receive with the third label according to the third label, The first display area and the second display area of the first display screen PL1 can display correct display data.

藉此，多屏顯示裝置3可僅透過單一個應用處理器AP同時驅動第一顯示屏PL1(主屏)與第二顯示屏PL2(副屏)顯示其應該顯示的畫面，而無需額外設置另一應用處理器。 In this way, the multi-screen display device 3 can simultaneously drive the first display screen PL1 (main screen) and the second display screen PL2 (sub-screen) to display the screen it should display through only a single application processor AP, without additionally setting another screen application processor.

綜合上述內容可知：相較於先前技術，本發明所提出的多屏顯示裝置可僅透過單一個應用處理器同時驅動主屏與副屏顯示其應顯示的畫面，故可大幅降低系統硬體之需求且能夠避免不同應用處理器之間的溝通。 Based on the above content, it can be seen that, compared with the prior art, the multi-screen display device proposed by the present invention can drive the main screen and the sub-screen to display the images to be displayed at the same time through only a single application processor, so the requirement of system hardware can be greatly reduced And can avoid communication between different application processors.
