Abstract

The invention provides a lighting test module. The lighting test module is used for performing the lighting test for a display panel, the lighting test module comprises a data voltage generating circuit arranged on a peripheral circuit board, wherein the data voltage generating circuit is used for providing a data voltage for preset data lines contained by the display panel during the lighting test. The lighting test module is advantaged in that during the lighting test, the data voltage generating circuit providing the data voltage is arranged outside the display panel and is subjected to hardwareization, the data voltage is provided by the data voltage generating circuit for the preset data lines, the quantity of the preset data lines is flexible and variable, the lighting test module isespecially suitable for unconventional, low resolution display panel development or process validation, and the process is simple during process validation of the display panel.

Description

Technical field [0001] The invention relates to the field of display technology, in particular to a lighting test module. Background technique [0002] The liquid crystal glasses do not need color film. The special panel (panel) of the concave-convex lens is realized by controlling the liquid crystal inversion simulation. The number of data lines required for the liquid crystal glasses is small. The conventional source driver is used, and the binding size is limited. The number of lines causes waste. At this stage, the process verification is mainly through a series of work stages such as array substrate production, Cell (boxing), Cutting (cutting), Cell Test (boxing test), Bonding (binding), lighting, etc., and finally assembled into a display module group. The shortcomings of some display panels can be found in the box test stage. Whether the process is feasible requires binding Driver IC (Integrated Circuit, integrated circuit) and binding flexible circuit boards, which can b...
