Embodiment Construction

[0023] Please refer to image 3 as well as Figure 4 , image 3 It is a schematic diagram showing the data structure of the data channel (DDC) of the present invention, Figure 4 for image 3 Schematic diagram of the format of each set of timing information in. In the data structure of the display data channel (DDC) of the present invention, in addition to the existing system data, timing requirements and specification descriptions using 128 bytes of memory space, another 128 bytes of memory space is used to store multiple sets of timings. Information (timing information). Such as image 3 As shown, a computer host (not shown) includes: a first storage block 20 and a second storage block 22, each using 128 bytes of memory space, the first storage block 20 stores system data 24 and timing requirements 26 And the specification description 28, and the second storage block 22 stores multiple sets of timing information 30. When the computer host connects a new display to the display ca...

Abstract

It's a kind of display data transmission method between a electronic apparatus and a display apparatus. This electronic apparatus comprises a display circuit and a presetting first display data. The display apparatus comprises a second display data. The method is: connecting the electronic apparatus with the display apparatus; the display apparatus transfers the second display data to the electronic apparatus, then compares the first display data and the second display data, then generates the third display data within this electronic apparatus. At last, the third display data can be transferred to the display apparatus through the electronic apparatus. So the display apparatus can display iamge by the third display data.

Description

Technical field [0001] The invention provides a method for transmitting display data between an electronic device and a display device, in particular to a method for transmitting display data after comparing the display data of the electronic device and the display device. Background technique [0002] In the development of computer multimedia technology, monitors and display cards responsible for image output have always played an important role. In order to comply with the existing plug and play (PNP) specifications, the current display data channel (DDC) is mostly used to transmit display data between the display and the display card, that is, the display will change its hardware specifications. The data is directly transmitted to the display card in the host, so that the display card can drive the display. Since the display cards of various brands have different setting methods for the display mode of the display, they often cause compatibility problems with each other. For e...
