Description

一种电视机芯板测试装置
本申请基于申请号为CN2015211431256、申请日为2015年12月31日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
【技术领域】
本发明实施例涉及电视机芯板测试技术领域，尤其涉及一种电视机芯板测试装置。
【背景技术】
目前的电视机芯板生产出来后要经过严格的测试后才能用于电视机整机组装，而目前工厂生产测试过程中都是用对应机型的液晶屏(LCD panel)搭设显示设备用于测试电视机芯板的功能。对于小尺寸电视还能应付，但对于50英寸以上的大屏电视就显的捉襟见肘，尤其是目前电视分辨率及接口类型不同，无法实现固定用某款液晶屏来测试。
【发明内容】
为了克服现有的相关产品的所有不足，本发明提出一种电视机芯板测试装置，该装置能使不同分辨率、不同接口类型的机芯板共用某款普通的小尺寸电视机或监视器作为显示设备。
本发明实施例解决其技术问题所采用的技术方案是：
本发明实施例所提供的一种电视机芯板测试装置，包括：电视机芯板、信号转换器以及显示设备；所述电视机芯板与信号转换器通过缆线电性连接，所述信号转换器与显示设备通过接口线电性连接。
作为本发明实施例的进一步改进，所述电视机芯板传输出的测试信号类型包括V BY ONE和LVDS。
作为本发明实施例的进一步改进，所述信号转换器包括第一转换元件、第 二转换元件以及第三转换元件，所述第二转换元件分别与第一转换元件和第三转换元件电性连接。
作为本发明实施例的进一步改进，所述显示设备包括带数字视频接口或高清晰度多媒体接口的电视机或监视器等。
作为本发明实施例的进一步改进，所述电视机芯板与信号转换器通过缆线电性连接，所述信号转换器与显示设备通过接口线电性连接。
与现有技术相比，本发明有以下优点：
将机芯板输出的V BY ONE和LVDS信号通过信号转换器转换成普通的小尺寸电视机或监视器都能接收的信号，使机芯板的测试不受液晶屏规格和尺寸的限制，增加了显示设备的共用性。。
