Description

显示装置的数据保护系统及保护方法 技术领域
本申请涉及显示技术领域，具体涉及一种显示装置的数据保护系统及保护方法。
背景技术
显示器中，系统主板通过线路连接至控制板(Control Board，C-Board)，控制板通过如柔性扁平电缆(Flexible Flat Cable，FFC)连接印制电路板(PCB)，印制电路板再通过源极覆晶薄膜(Source-Chip on Film，S-COF)和栅极覆晶薄膜(Gate-Chip on Film，G-COF)与显示区连接。显示器驱动方式包括：系统主板将颜色(例如：R/G/B)压缩信号、控制信号及电源传输至控制板。信号经过时序器(Timing Controller，TCON)处理后，传输至源极驱动电路(Source Driver)及栅极驱动电路(Gate Driver)。通过相关的集成电路或芯片将必要性的数据与电源传输于显示区，从而使得显示器获得呈现画面需求的电源、信号。
在显示器的驱动板上，设置有可编程可擦除型存储器(EEPROM)，设置为存储时序器的控制数据与设定(TCON Code)。但时序器在读取数据时，经常容易发生EEPROM中存储的数据被改写的事情。在显示装置开机、系统导入或相关作业期间，时序器会读取EEPROM里面存储的控制数据，完成时序器的初始化设定。EEPROM的写保护信号(Write Protect，WP)，常态下为高电位(H)，即正常状态下都要处于写保护状态。然而，由于线材或其他干扰，可能会导致写保护信号也会被失效，那么就有可能会出现误动作而导致EEPROM里面存储的控制数据被改写，进而会造成显示画面异常，错误频出。

为更进一步阐述本申请为达成预定申请目的所采取的技术手段及功效，以下结合附图及可选的实施例，对依据本申请提出的一种显示面板及其应用的显示装置，其具体实施方式、结构、特征及其功效，详细说明如后。
