Abstract
Disclosed is a method for improving transmittance of flat or curved liquid crystal display panel. The method includes the following steps. (1) A substrate is manufactured according to the BPS technology. The substrate includes an array substrate and a CF substrate. A spacer and a black matrix are provided on a side of the array substrate and a transparent conductive electrode film is provided on a side of the CF substrate. (2) Marks are engraved on designated positions of the CF substrate by means of a laser and the CF substrate is aligned with the marks on a platform of a UV2A exposure machine. (3) Tracking lines are engraved on the transparent conductive electrode film and a region bounded by the tracking lines is aligned with a light-shielding region of a gate line or a light-shielding region of a data line on the side of the array substrate. (4) The substrate is exposed to light and a mask is used to track the tracking lines. The method, by taking advantage of a laser patterning method, overcomes the technical prejudices and enables the BPS technology to be compatible with the UV2A technology. Besides, a satisfactory transmittance can also be obtained through the method.
