DISPLAY PANEL ASSEMBLY, REGULATION METHOD THEREFORE, AND DISPLAY APPARATUS

摘要

A display panel assembly comprises a display panel (100), a driving circuit (140), and a control circuit (143). The display panel (100) is provided with a display region (110) and a fan-out region (120). Multiple first data lines (111) are disposed in the display region (110). Multiple second data lines (121) with multiple lengths are disposed in the fan-out region (120) and are connected to the first data lines (111). The driving circuit (140) comprise a function circuit (142) and an adjustable resistor group (145) connected to an output end of the function circuit (142). The second data lines (121) are coupled to the output end of the function circuit (142) by mans of the adjustable resistor group (145). The adjustable resistor group (145) is used for reducing an impedance difference of a connection line between the output end of the function circuit (142) and the first data lines (111). The control circuit (143) is used for controlling a resistance value of the adjustable resistor group (145).
