Description

显示装置、显示系统 技术领域
本申请涉及显示领域，尤其涉及一种显示装置、显示系统。
背景技术
一般液晶显示装置主要包括设置在液晶面板(Panel)上的源驱动电路、栅驱动电路，水平方向电路板(X-board，简称XB板)，设置在系统板或主板(MB)上的系统级芯片(Sygtem On Chip，简称SOC)、时序控制器(Timing Control，简称TCON)，通常通过柔性扁平电缆(Flexible Flat Cable，简称FFC)米连接模块主板(MB板)和水平方向电路板(XB板)，以进行二者之间的信号传输，其中，系统级芯片接收待传输图像数据信号，并将所述待传输图像数据信号输出，随后将输入信号经过行扩展模块和列扩展模块进行处理，将处理后的数据传送给时序控制器，时序控制器将接收到的数据通过水平方向电路板传输至源驱动电路和栅驱动电路，从而驱动面板进行显示。
随着各个液晶面板厂产能释放，大尺寸液晶面板竞争激烈，价格下行压力大。大尺寸电视整机厂商为降低成本，逐渐由Normal型液晶面板(包含控制板(CB)的设计)转为采用TCONLESS型液晶面板。TCONLESS型液晶面板相关技术中TCON全部或部分功能由系统板(MB板)上的系统级芯片(SOC)实现，MB板上SOC增加TCON功能后其面积可以保持不变。
现行P2P(point-to-point)协议种类较多，如ISP(Integrated-Stream Protocol)、USI-T(Unified Standard Interface for TV)、CHPI(China BOE Point-to-Point Interface)、CSPI(China Star Point-to-Point Interfaoe)、CMPI(Clock Embedded Point-to-Point Interface)、CEDS(Clock Embedded Differential Signal)等，应用于不同的面板厂商，使用不同的P2P协议，图像数据格式和TX(Transmit)与RX(Receive)间的training方式都会不同，这会导致不同的源驱动器(Source Driver，简称S/D)所支持的P2P协议不尽相同，则系统板需要根据不同P2P协议做出不同设计，系统板通用性差。
另外，如图1所示，现行Normal型液晶面板的面板结构设计中的资料(数据)传输路径为：SOC→CB→XB→panel，其中，SOC与CB上的TCON IC通过VBYONE(V-by-One或VBO)协议传输液晶面板控制资料和数据资料，TCON IC将接收到的资料转为mini-LVDS格式传输给XB，同时，TCON IC还包括白平衡(ACC)、过压驱动(OD)、消除面板显示不均(Demura)等光学调整功能；而TCON-less设计的资料传输路径SOC→XB→panel，其中，SOC与XB通过P2P接口协议传输液晶面板控制资料和数据资料。
现行Normal(XB+CB)架构的，光学调整功能需要由TCON IC来完成，CB成本较高；而现行TCON-less架构的S/D需搭配使用P2P接口，较mini-LVDS接口的S/D，制造和测试成本增加：因无TCON，Panel Timing(时序)由SOC产生，Panel Timing调试和改版需要SOC来配合，SOC改版困难周期长，且成本高：不利于Panel新技术发展；COF(Chip-On-Film，覆晶薄膜)机种与GOA(Gate on Array)机种的面板所需时序信号不同，SOC兼容性差；不同面板的GOA电路设计不同，所需时序信号亦存在差异，SOC兼容性差。

【实施例五】
如图2所示，本实施例中提供的一种新型的显示装置10，包括；显示面板(Panel)111；驱动模组，电连接所述显示面板111，包括源极驱动模块(也称源极驱动电路)1115和栅极驱动模块(也称栅极驱动电路)1113：水平方向电路板(XB)113，电连接所述源极驱动模块1115和栅极驱动模块1113，水平方向电路板113例如包括左水平方向电路板(XL)113a和右水平方向电路板(XR)113b：系统板(MB)13，电连接所述水平方向电路板113，其上具有系统级芯片(SOC)131a；功能模块(也称功能电路)1130，包括伽玛(Gamma)模块(也称伽玛电路)、电源(DC-DC)模块(也称电源电路)、时序控制芯片(ST IC)、电平转换(Level Shifter，简称L/S)模块(也称电平转换电路)；其中，所述时序控制芯片(ST IC)设置于所述水平方向电路板(XB)113上，用于高速信号转换，不具有光学调整功能。
需要说明地是，图2所示的显示装置10中，功能模块1130中的四个框线模块仅为示例，并不构成 对Gamma模块、DC-DC模块、L/S模块不全在XB上的限制。
进一步地，所述源极驱动模块1115上具有COF型源驱动器(Source COF)1115S；所述伽玛模块用于产生Gamma电压；所述电源模块用于产生显示装置的整个电路所需的电源(power)信号；所述时序控制芯片(ST IC)用于将所述系统级芯片输出的P2P或VBO高速信号转换为mini-LVDS信号。
进一步地，所述电平转换模块基于所述时序控制芯片产生栅极驱动模块的时序控制信号；所述栅极驱动模块为GOA。需要说明地是，对于此GOA机种，Gate OnArray而无Gate COF，即无Gate Driver IC，而具有L/S模块——电平转换模块。
进一步地，所述伽玛模块、所述电源模块、所述电平转换模块不全设置于所述水平方向电路板上，例如所述电平转换模块设置于所述水平方向电路板上；所述电源模块设置于所述主板上，提供所述电平转换模块所需的电源信号。例如，本实施例提出的GOA+TCONLESS的面板架构或显示装置，其MB上包括SOC、产生Gamma电压Gamma模块、产生显示装置的整个电路所需的power信号的DC-DC模块、以及其他周边元件(Peripheral component)；XB包括ST IC、产生GOA控制信号的Level Shifter模块、以及其他周边元件(Peripheral component)，搭配mini LVDS的Source driver IC和扫描方向的GOA电路。
具体地，如图7所示，基于前述方案，本实施例提出一种显示装置的优化方案，具体为；L/S模块设置于XB上，MB仅需提供L/S模块所需power，可有效兼容不同GOA面板，即优化MB-XB接口定义，也可提高MB兼容性。此方案通过将ST IC、L/S模块设置在XB上，将DC-DC模块、Gamma模块兼容在系统厂的MB上：但不限定ST IC、L/S模块在XR/XL上，也不限定XB数量；该系统架构的具体实施中，各功能模块及信号流转如图8所示。
本实施例的显示装置，较Normal架构减少CB，可以将MB与XB间连接由双排线插拔改为单排线插拔，排线插拔带来的损耗减半，可有效降低成本；较Normal架构减少CB，也可有效降低成本；较现行TCON-less架构，XB上增加ST IC，S/D使用mini-LVDS接口，可降低S/D自身的成本；ST IC可产生Panel所需Timing，可有效降低SOC调试周期；ST IC也可以包含新技术IP单元(也称IP核)， 有利于面板技术优化；另外，对Gamma模块、DC-DC模块、Level Shifter模块等分别合理设置于MB或XB上，提升总体科学性及兼容性。
