Abstract
With the rapid increase in size and frame rate of TV products, high‐ speed data transmission has become a major issue to be solved. This paper studied the PCB impact factors of high‐speed digital signal transmission on large‐sized display panels, like channel loss, crosstalk between adjacent signals, etc. Simultaneously, improvement methods for signal amplitude attenuation in panel transmission systems was proposed. Based on 98’ 4K 120Hz TV product platform, the signal attenuation of transmission system was evaluated, and the effectiveness of the improvement schemes also was verified, the result shows signal quality in system can be improved above 20%.
