Abstract

A display device (10) and a display device (10) load testing method. By means of a timing controller (11) receiving and executing an eye pattern enlarging instruction output by an inner integrated circuit bus controller (13) to correspondingly output an eye pattern enlarging drive signal to a driving chip (14), influence on the determination of a load testing result due to the serious attenuation of a drive signal during the load testing of the display device (10) is avoided, thereby improving the accuracy of the load testing of the display device (10).

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display device and a method for on-load testing of the display device. Background technique [0002] After the display device is manufactured, it is necessary to judge the accuracy of the mass production code burned in the flash memory of the printed circuit board (Printed Circuit Board Assembly, PCBA). The mass production code includes various control circuits (sequence control circuit, programmable gamma correction buffer circuit and digital power management integrated circuit, etc.) data information required for operation. When judging the mass production code, it is necessary to use a jumper to transmit the test signal output by the test equipment to the control circuit on the printed circuit board for processing, and the control circuit needs to run the mass production code to be in a working state to process the test signal. The final test signal is transmitte...
