Abstract
The invention provides a testing device and a testing method which are used for a liquid crystal module. The testing device comprises a vibration platform capable of vibrating in a vertical direction, a cover cap and a plurality of striking elements. The cover cap is detachably arranged on the vibration platform, and forms accommodation space between the vibration platform and the cover cap to accommodate the liquid crystal module to be tested and the plurality of striking elements to be tested. The plurality of striking elements are arranged in the accommodation space and are used for striking a panel of the liquid crystal module to be tested when the vibration platform vibrates to check whether anomaly of liquid crystal quantity exists. When the testing device tests the anomaly of the liquid crystal quantity of the liquid crystal module, the plurality of striking elements can strike the panel of the liquid crystal module to be tested in a dynamic and multi-point mode, and can better and more accurately confirm whether the anomaly of liquid crystal quantity of the liquid crystal module to be measured exists or not, and therefore product quality is improved, and customer complaints are reduced.
Description
technical field [0001] The invention relates to the technical field of liquid crystal module testing, in particular to a testing device and a testing method for a liquid crystal module to test whether there is an abnormal liquid crystal quantity. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD for short) uses the optical anisotropy and birefringence properties of liquid crystal molecules to control the transmission of light through TFT switches and signal voltage input to display images. In the liquid crystal display panel (Panel), the color filter (Colorfilter) substrate and the TFT substrate are boxed together by frame glue, and there is a spacer (PhotoSpacer) support in the middle of the two-layer substrate to form a certain interval (Cellgap) between the two-layer substrate. ), so that a liquid crystal filling area is formed between the two substrates to fill the liquid crystals, and the liquid crystal molecules in the liquid crystal fi...
