Description

模组厂供客户端快速识别模组供应商的方法
技术领域
本发明涉及显示模组技术领域，尤其涉及一种模组厂供客户端快速识别模组供应商的方法。
背景技术
在目前的液晶模组行业中，客户端同一个项目往往有多家不同的显示模组供应商，对于同一项目不同模组供应商提供的成品模组，在外观上往往难以分辨是出自于哪一家模组供应商，在外观上仅有FPC丝印上可以得到区分，但是各家模组厂对于FPC的丝印命名都有自己的规范，导致客户端单通过丝印很难去辨别，而且仅通过FPC丝印去辨别模组供应商这种做法不仅时效性低，而且也可能出现误判，以至于将模组用错，导致装错屏的不良品流出，进而造成终端客户装机后，出现整机闪屏、不显、电流异常、功耗偏高等问题，引起终端客户投诉、罚款。因此，现有技术存在缺陷，需要改进。
发明内容
本发明的目的是克服现有技术的不足提供一种通过软硬件结合的技术，从软件和硬件两个方面来精准识别模组的供应商，可以很好的规避通过识别模组FPC上丝印来人为判断模组供应商准确性低、效率低、成本高、极易出现误判的问题，从而避免客户将装错屏的不良品流出到终端客户，规避后续可能造成的损失及风险，具体是提供一种模组厂供客户端快速识别模组供应商的方法。
本发明的技术方案如下：本发明一种模组厂供客户端快速识别模组供应商的方法，包括以下步骤：步骤1：分别通过第一方法和第二方法得到模组供应商，步骤2：将所述第一方法和第二方法得到的模组供应商结果进行比对；步骤3：若步骤2的比对结果相同，则输出模组供应商；
其中：第一方法为：在模组FPC上设置电压检测电路；通过检测电压检测电路的电压并进行对比来判定模组供应商；第二方法为：通过识别模组的寄存器的地址和值并进行对比来判定模组供应商。
进一步地，所述第一方法中，电压检测电路包括第一电阻和第二电阻，所述第一电阻一端与电源端电性连接，所述第一电阻的另一端分别与检测端、第二电阻的一端电性连接，所述第二电阻的另一端接地。
进一步地，所述电压检测电路中，包括分压结构一和/或分压结构二和/或分压结构三；其中，
所述分压结构一为：第一电阻的阻值不为0，第二电阻的阻值为0；
所述分压结构二为：第一电阻的阻值为0，第二电阻的阻值不为0；
所述分压结构三为：第一电阻和第二电阻的阻值均不为0。
进一步地，在所述步骤3中，若步骤2的比对结果不同，则进入步骤4；所述步骤4为：再进行一次步骤1和步骤2，若比对结果相同，则输出模组供应商。
进一步地，所述步骤4中，若比对结果依旧不同，则输出识别失败的结果。
采用上述方案，本发明的有益效果在于：本方案通过软硬件结合检测和对比的方式，通过硬件和软件两个维度与设定值进行对比，进而快速、准确地识别模组来自于哪家供应商，从而避免了人工从模组FPC丝印来判断模组供应商带来的不准确性、效率低等问题，避免了将装错模组的产品出给到终端客户装机进而可能造成的风险，大大降低了隐患，减少了可能造成整机有显示不良甚至报废的风险及经济损失。
附图说明
图1为本发明一实施例的电压检测电路的电路图。
具体实施方式
以下结合附图和具体实施例，对本发明进行详细说明。
请参阅图1，在本实施例中，本发明提供一种模组厂供客户端快速识别模组供应商的方法，包括：包括以下步骤：步骤1：分别通过第一方法和第二方法得到模组供应商。其中：第一方法为：在模组FPC上设置电压检测电路；通过检测电压检测电路的电压并与预存的数据进行对比，来判定模组供应商，在预存的电压值中，特定的电压值对应特定的模组供应商，当检测得到的电压值与预存的数据匹配时，则可以判断为该模组供应商的产品。第二方法为：通过识别模组的寄存器的地址和值并进行对比来判定模组供应商，此方法在模组上电后读取寄存器寄相应的地址和值，系统可根据回读到的地址和值并根据预存的对应芯片来判断此对应的地址和对应的值是来自于哪一家模组供应商，也可以准确、快速的识别出模组供应商。
步骤2：将所述第一方法和第二方法得到的模组供应商结果进行比对。步骤3：若步骤2的比对结果相同，则输出模组供应商。例如所述第一方法和第二方法得到的模组供应商是A，此时则结果相同，可以输出模组供应商为A
进一步地，所述第一方法中，电压检测电路包括第一电阻R1和第二电阻R2，所述第一电阻R1一端与电源端(本实施例中为IOVCC端，电压为1.8V)电性连接，所述第一电阻R1的另一端分别与检测端(本实施例中为LCD_ID端)、第二电阻R2的一端电性连接，所述第二电阻R2的另一端接地。
进一步地，所述电压检测电路中，包括分压结构一和/或分压结构二和/或分压结构三；其中，
所述分压结构一为：第一电阻R1的阻值不为0，第二电阻R2的阻值为0，此时LCD_ID端检测电压为IOVCC的电压(1.8V)。
所述分压结构二为：第一电阻R1的阻值为0，第二电阻R2的阻值不为0，此时LCD_ID端检测的电压为0V。
所述分压结构三为：第一电阻R1和第二电阻R2的阻值均不为0。此时LCD_ID端检测的电压＝IOVCC/(R1+R2)*R2。
通过硬件ID电路的设计，模组上电后LCD_ID信号检测脚会读取到相应的电压值，模组厂对应特定的电压值可由客户端设定，进而模组厂FPC搭配相应硬件ID电路的分压电阻R1、R2电阻值，得到客户想要的特别电压值，即可实现模组一上电，系统通过读取LCD_ID电压值快速准确的判断出模组供应商。
进一步地，在所述步骤3中，若步骤2的比对结果不同，则进入步骤4；所述步骤4为：再进行一次步骤1和步骤2，若比对结果相同，则输出模组供应商。
进一步地，所述步骤4中，若比对结果依旧不同，则输出识别失败的结果。
综上所述，本发明的有益效果在于：通过软硬件结合检测和对比的方式，通过硬件和软件两个维度与设定值进行对比，进而快速、准确地识别模组来自于哪家供应商，从而避免了人工从模组FPC丝印来判断模组供应商带来的不准确性、效率低等问题，避免了将装错模组的产品出给到终端客户装机进而可能造成的风险，大大降低了隐患，减少了可能造成整机有显示不良甚至报废的风险及经济损失。
以上仅为本发明的较佳实施例而已，并不用于限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
