Description
Technical Field
The present disclosure relates to the field of display, and in particular, to a novel display device and a display system.
Background
Generally, a liquid crystal display device mainly includes a source driving circuit, a gate driving circuit, a horizontal direction circuit board (X-board, abbreviated as XB board), a System On Chip (SOC) disposed On a System board or a main board (MB board), and a Timing Controller (TCON), wherein the System On Chip (SOC) is connected to the circuit main board and the horizontal direction circuit board through a Flexible Flat Cable (FFC) for signal transmission therebetween, wherein the System On Chip receives an image data signal to be transmitted and outputs the image data signal to be transmitted, and then the input signal is processed by a line expansion module and a column expansion module, and the processed data is transmitted to the Timing controller, which transmits the received data to the source driving circuit and the gate driving circuit through the horizontal direction circuit board, thereby driving the panel to display.
With the release of the capacity of each liquid crystal panel factory, the large-size liquid crystal panel is highly competitive, and the price descending pressure is large. In order to reduce the cost, large-sized television manufacturers gradually change from Normal (including Control Board (CB) design) to TCONLESS lcd panels. In the related technology of the TCONLESS type liquid crystal panel, all or part of TCON functions are realized by a system-on-chip (SOC) on a system board (MB board), and the area of the SOC on the MB board can be kept unchanged after the TCON function is added; the ST IC is collectively called a Small TCON IC, has a signal conversion function, and can convert, for example, a P2P signal into a mini-LVDS (mini low voltage differential signaling) signal for output.
The existing P2P protocols are of various types, such as ISP, USIT, CHPI, CSPI, CMPI, CEDS, etc., and are applied to different panel manufacturers, different P2P protocols are used, image data formats and tracking modes between TX RX are different, which may cause different P2P protocols supported by different Source drivers (S/D) to be different, and thus a system board needs to be designed differently according to different P2P protocols, and the system board has poor universality.
In addition, as shown in fig. 1, the data transmission path in the Normal design of the current panel structure is: SOC → CB → XB → panel, wherein the SOC and TCON IC on CB transmit the control data and data of the liquid crystal panel through VBYONE (V-by-One or VBO) protocol, the TCON IC converts the received data into mini-LVDS format and transmits the mini-LVDS format to XB, meanwhile, the TCON IC also comprises the optical adjustment functions of white balance (ACC), over-voltage drive (OD), Demura (eliminating panel display unevenness) and the like; and the data transmission path of TCON-less design SOC → XB → panel, wherein SOC and XB transmit the liquid crystal panel control data and data through P2P interface protocol.
The VBO interface of the existing Normal (XB + CB) framework only transmits control data and data of an image, the optical adjustment part needs a TCON IC to complete, and the CB cost is higher; the S/D of the existing TCON-less framework needs to be matched with a P2P interface, so that compared with the S/D of a mini-LVDS interface, the manufacturing and testing cost is increased; because there is no TCON, the Panel Timing is produced by SOC, the Panel Timing debugging and the revision need the SOC to cooperate, the SOC revision is difficult for a long period, and the cost is high; is not beneficial to the development of the Panel new technology; the timing signals required by the panels of a COF (Chip-On-Film) model and a GOA (Gate On array) model are different, and the SOC compatibility is poor; different GOA circuit designs of different panels are different, required time sequence signals are different, and SOC compatibility is poor.

As shown in fig. 2, the novel display device 10 provided in the present embodiment includes: a display Panel (Panel) 111; the driving module is electrically connected with the display panel 111 and comprises a source driving module 1115 and a gate driving module 1113; a horizontal direction circuit board (XB)113 electrically connected to the source driver block 1115 and the gate driver block 1113; a system board (MB)13 electrically connected to the horizontal direction circuit board 113 and having a System On Chip (SOC)131a thereon; a function module 1130 including a Gamma (GM) module, a power supply (DC-DC) module, a small-sized timing control chip (ST IC), and a Level Shifter (Level Shifter) module; wherein, the said small-scale time sequence control chip (ST IC) is set up on the said horizontal direction circuit board (XB)113, is used for the high-speed signal conversion, does not have the optical adjustment function.
In the display device 10 shown in fig. 2, the four frame line modules in the function module 1130 are merely examples, and do not limit GM, DC-DC, and L/S to XB.
Further, the Source driving module 1115 is provided with a Source driver (Source COF) 1115S; the Gamma module is used for generating Gamma voltage; the power supply module is used for generating a power supply (power) signal required by the circuit; the small-sized time sequence control chip (ST IC) is used for converting P2P or VBO high-speed signals output by the system-on-chip into mini-LVDS signals.
Furthermore, the functional module also comprises a level conversion module; the level conversion module generates a time sequence control signal of the grid drive module based on the small time sequence control chip; the gate driving module is GOA. For this GOA model, the Gate On Array has no Gate COF, i.e., no Gate Dirver IC, and has an L/S-level conversion module.
Furthermore, the gamma module, the power module and the level conversion module are not all disposed on the horizontal circuit board, for example, the level conversion module is disposed on the horizontal circuit board; the power supply module is arranged on the mainboard and provides a power supply signal required by the level conversion module. For example, the panel structure or display device of GOA + TCONLESS proposed in this embodiment includes an SOC, a module for generating Gamma voltage GM, a DC-DC module for generating power signals required by the circuit, and other peripheral components on MB; the XB consists of an ST IC, a Level Shifter module for generating a GOA control signal and other peripheral elements, and is matched with a Source driver IC of mini LVDS and a GOA circuit in the scanning direction.
Specifically, as shown in fig. 7, based on the foregoing embodiment, an optimization scheme is proposed, where L/S is limited to XB, and MB only needs to provide power required by L/S, so that different GOA panels can be effectively compatible, that is, MB-XB interface definitions are optimized, and MB compatibility can also be improved. The scheme limits ST IC, L/S on XB, DC-DC, Gamma compatible on system factory MB; ST IC and L/S are not limited to XR/XL, and the quantity of XB is not limited; in the implementation of the system architecture, the functional modules and signal flow are shown in fig. 8.
The display device of the embodiment can change the connection between the MB and the XB from double-row wire plugging to single-row wire plugging, reduces the loss caused by the wire plugging by half, and can effectively reduce the cost; compared with a Normal framework, CB is reduced, and cost can be effectively reduced; compared with the existing TCON-less architecture, ST IC is added on XB, S/D uses mini-LVDS interface, and the cost of S/D can be reduced; ST IC can generate Timing required by Panel, and can effectively reduce SOC debugging period; the ST IC can also comprise a new technology IP unit, which is beneficial to the optimization of panel technology; in addition, the GM module, the DC-DC module, the Level Shifter module and the like are reasonably arranged on the MB or the XB respectively, so that the overall scientificity and compatibility are improved.
