显示设备和测试显示设备的方法
摘要：
本发明涉及显示设备和测试显示设备的方法。显示设备包括：延迟生成电路，该延迟生成电路生成基准信号和竞争信号，该竞争信号是基于延迟设置信号而生成的；输入顺序判断电路，该输入顺序判断电路判断基准信号和竞争信号的输入顺序；延迟设置电路，该延迟设置电路基于输入顺序判断电路中的判断结果而生成延迟设置信号；以及内部同步控制电路，该内部同步控制电路控制CPU和显示面板之间的显示数据的传输。使用基准信号和竞争信号执行内部同步控制电路的操作测试。因此，能够提高故障检出率。
摘要（英）：

A display apparatus includes a delay generation circuit that generates a reference signal and a competing signal, the competing signal being generated based on a delay set signal, an input order judgment circuit that judges an input order of the reference signal and the competing signal, a delay set circuit that generates the delay set signal based on a judgment result in the input order judgment circuit, and an internal synchronous control circuit that controls transfer of display data between a CPU and a display panel. An operation test of the internal synchronous control circuit is performed using the reference signal and the competing signal. Hence, fault coverage can be enhanced.
