随着液晶电视尺寸的增大以及解析度的升高，需要传输的数据也日益增多，由此差分信号作为一种高速的传输协议便得到普及，数据传输的质量也面临更严峻的考验，只有在电压幅值(电压幅值的大小对应数据的高电平和低电平)满足要求时，数据才能存储在寄存器中以使数据传输准确无误。With the increase in size and resolution of LCD TVs, the data that needs to be transmitted is increasing. As a result, differential signals are popularized as a high-speed transmission protocol, and the quality of data transmission is also facing a more severe test. When the voltage amplitude (the magnitude of the voltage amplitude corresponds to the high level and low level of the data) meets the requirements, the data can be stored in the register to make the data transmission accurate.
然而，随着差分对数量的增多及驱动板日益的薄型化，再加上传输数据的增加，以及由于传输的数据始终在变化，实际接收到的数据幅值状况复杂多变，使得数据传输的幅值状况越来越糟糕，从而在实际应用中需要耗费大量的时间来进行人工调试，确保每一对的差分传输状况，耗时耗力。However, with the increase in the number of differential pairs and the increasingly thinner driver boards, coupled with the increase in transmitted data, and because the transmitted data is always changing, the actual amplitude of the data received is complicated and variable, making data transmission The amplitude condition is getting worse and worse, so in practice, it takes a lot of time to manually debug to ensure the differential transmission status of each pair, which is time-consuming and labor-intensive.
