Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The existing technology has the following drawbacks: due to high hardware requirements (for example: high requirements for the chip of the host SOC, multiple DSI serialization chips and display interface should be left on the chip, and the connection line between the host and the display screen is long. , the requirement for the number of MIPI-DSI interfaces is also high), resulting in high costs, restrictions on the number of display screens, and the display requirements of each display screen are not considered during display, resulting in poor customer experience. Based on this, the purpose of the present invention is to provide a display system, method and device based on daisy chain connection, which can realize on-demand distribution according to the pixel requirements of the display screen and improve customer experience.

In order to facilitate the understanding of this embodiment, a display system based on a daisy chain connection disclosed in the embodiment of the present invention is first described in detail.

Example 1:

As shown in FIG. 2 , a display system based on daisy chain connection provided by an embodiment of the present invention includes: a host 10 and a plurality of display modules. The host 10 includes a host chip 11 and a first conversion module 12 connected to the host chip. , each display module includes a second conversion module, and a corresponding display screen;

The host chip 11 forms a daisy-chain connection relationship with all display modules; wherein, the daisy-chain connection relationship is as follows: a second conversion module (ie, the target conversion module 201 in FIG. 3 ) of a target display module 20 is connected to the first conversion module 12 . , the second conversion modules of the remaining display modules 21 (ie, the remaining conversion modules 211 in FIG. 3 ) are connected with the second conversion modules of the target display module 20 in a cascaded manner; in practical applications, any display can be selected according to the actual The module is regarded as the target display module 20, and the other display modules 21 are display modules other than the target display module 20;

The workflow of the system is as follows: the host chip 11 is used to determine the pixel requirements of each display module, and allocate pixel information to each display module based on the pixel requirements of each display module. The host chip 11 sends the original signal, so that the original signal is converted by the first conversion module 12 and the second conversion module to obtain the display content information corresponding to each display screen. The display screen (including the target display screen 202 and other display screens 212 in FIG. 3 ) is used to display corresponding display content information based on the allocated pixel information.

The above-mentioned original signal includes: MIPI_DSI signal and/or MIPI_DP signal, and the signal used for displaying the content information includes at least one of the following: LVDS signal, EDP signal and RGB signal. The first conversion module 12 is a serializer Ser, and Ser is used to convert the MIPI_DSI signal or MIPI_DP signal into a FPD-LINK signal or a GMSL signal; the second conversion module is a deserializer Des, and Des is used to convert the FPD-LINK signal or GMSL signal The signal is converted to display content information. The display screen in this embodiment may be a TFT (Thin Film Transistor, thin film field effect transistor) display screen. It should be noted that this embodiment does not impose any restrictions on the type of the display screen.

The second conversion module of one target display module 20 can be connected to the first conversion module 12 by means of daisy-chain connection, and the second conversion modules of the remaining display modules 21 can be connected to the second conversion module of the target display module 20 by cascading The modules are connected, not all display modules are connected to the first conversion module 12, so this embodiment can reduce the cost of the first conversion module 12, and there is no limit to the number of display screens. need to be allocated to improve customer experience.

In order to improve the transmission efficiency, in an optional embodiment, the FPD-LINK signal or the GMSL signal is transmitted from the Ser to the Des by means of coaxial transmission.

In order to allocate pixel information to each display screen according to the actual situation, in an optional embodiment, the host chip 11 is further configured to determine the maximum pixel size supported by the first conversion module 12, and the pixel information allocated to all the display screens is among the and does not exceed the maximum pixel size.

In this embodiment, the maximum pixel size supported by the output interface of the host can be used as the highest limit condition, so that the sum of the total pixel information of the split screen (that is, the above-mentioned display screen) does not exceed the maximum pixel supported by the SOC, and the display content of the split screen Information can be distributed arbitrarily. The host chip 11 allocates pixel information and display content information to each display screen. Specifically, each display module has I2C communication with the host chip 11 , so the pixel information and display content information of each display screen can be set through the host chip 11 .

In an optional embodiment, the host chip 11 is further configured to determine the position of each display module in the daisy chain, and assign a corresponding level to the corresponding display module according to the position. Among them, the display module connected to the host has the highest level, and the display module at the end of the daisy chain has the lowest level.

As shown in FIG. 3, an embodiment of the present invention provides another display system based on daisy-chain connection, which may include: an SOC (that is, the above-mentioned host chip), a Ser TX (that is, the above-mentioned serializer Ser), and three display modules, wherein the first display module includes a first Des and a digital instrument panel, the second display module includes a second Des connected to the first Des and a central information display screen, and the third display module includes a connection to the second Des The third Des and HUD display. The above Ser TX represents the transmitting end of the host, which can use any of the following types of chips: UH983, UH981 or MAX96745. The above-mentioned first Des and second Des both represent the receiving end of the display module, so any of the following types of chips can be used: UH984, UH988 or MAX96878. With only these three display modules, the third Des at the end of the daisy chain can use any of the following types of chips: UH948, UH928, UH926, MAX96752, MAX9678, or MAX9276.

The SOC has only one MIPI-DSI interface, and when the SOC has only one MIPI-DSI interface, a SerTX can be connected. However, when the SOC has multiple MIPI-DSI interfaces, multiple Ser TXs can be connected. That is to say, the output of the SOC has a same-level expansion, which can be divided into two. The above SOC can output a MIPI_DSI signal or MIPI_DP signal, Ser TX can convert MIPI_DSI signal or MIPI_DP signal into FPD-LINK signal or GMSL signal, and transmit FPD-LINK signal or GMSL signal to the first Des through coaxial or twisted pair , through the first Des can be converted into LVDS signal, EDP signal or RGB signal, at the same time can be divided into two groups of FPD-LINK signals connected to the second Des of the next display module through the transmission line. RX in Figure 3 represents the signal input terminal, and TX represents the signal output terminal. After RX is received, it can only drive the display screen under the corresponding display module, while TX can output the signal to the lower-level display module. It can be seen from FIG. 3 that there is no same-level extension between each display module, the display module connected to the Ser has the highest level, and the display module at the end of the daisy chain has the lowest level. The eDP/oLDI/RB/CSI-2 in the figure can all refer to the signal interface, and the signal interface is used to receive signals through RX and convert the received signals.

The host chip on the host side can use the DS90UB983-Q1 model, and the Ser on the host side converts the received signal into FPD-LINK signal or GMSL output, the chip on the display module side can use the DS90UB988-Q1 model, and the FPD-LINK signal is used as the display module input. Converted by Des to two sets of LVDS signal outputs to drive the display, and two sets of FPD-LINK signal outputs can be connected to the next level of display.

As shown in FIG. 4 , an embodiment of the present invention provides another display system based on daisy chain connection, which is applied to an automobile scene, including but not limited to: 3K central display screen, 2K cluster display screen, and the like.

As shown in FIG. 5 , an embodiment of the present invention provides another display system based on daisy-chain connection, including: a host computer, display 1, display 2 . . . until display N+1. Display 1 represents the display module with the highest level. The more times the screen is split, the lower the level. Display N+1 is the end of the daisy chain, representing the display module with the lowest level. All split-screen operations can only be performed under the same operating system, and different operating systems cannot perform split-screen operations. It should be noted that the level of the split screen cannot be skipped. If one second-level screen is reduced, the previous third-level screen becomes a second-level screen, and so on, which will not be repeated in this embodiment.

In this embodiment, on-demand allocation can be achieved through the pixel requirements of various display screens, and the pixel information of each display screen can also be arbitrarily allocated through software. Multi-screen interaction can also be achieved between each display screen. The host in this embodiment only needs one or a small number of display screen interfaces. When adding a screen, the screen is split from the display module end. Therefore, the split screen in this application can be flexibly increased or decreased based on the relationship of the daisy chain connection. Since this embodiment has lower requirements on the host chip, the cost of the host chip and the cost of the connecting wire consumables are both lower.

This embodiment describes a display system based on daisy-chain connection from the hardware structure. The main technical points of the system are as follows: (1) a DSI/DP interface drives the multi-screen display technology, which can reduce the cost of the host chip; (2) ) Multi-screen display interactive technology, which can improve the experience; (3) Video coaxial transmission with power line interface technology, the current display transmission generally uses twisted-pair transmission lines, and its transmission bandwidth is limited, about 6Gbps, while the same The bandwidth of axis transmission can reach 12Gbps, which can support larger pixel transmission and improve display efficiency.
