Title:
LIGHTING FIXTURE OF DISPLAY PANEL, AND LIGHTING TESTING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/192027
Kind Code:
A1
Abstract:
Disclosed are a lighting fixture of a display panel, and a lighting testing method. The lighting fixture comprises: a signal generator (11) for generating multiple paths of control signals and a first data signal; and a controller (12) connected to the signal generator (11) and used for lighting, when effective signals of the control signals and an effective signal of the first data signal are functioning at the same time, sub-pixels, corresponding to the control signals, in a corresponding row in a display panel, wherein the multiple paths of control signals respectively correspond to a plurality of sub-pixels in pixels in each column; in each period, the time positions of the effective signals of the control signals corresponding to the sub-pixels needing to be lit, and the time positions of the effective signal of the first data signal are the same; and the time positions of the effective signals of the remaining control signals are at a distance of a set time period away from the effective signal of the first data signal. Thus, it can be prevented that the effect of lighting testing is affected by mistaken charging of the other sub-pixels in the case of data signal delay.
