    • A process condition evaluation method for a liquid crystal display module (LCM) includes: a first step of obtaining a threshold power measuring pattern, an analysis sample for a cell bonding status in an LCD fabrication process, and obtaining a lower substrate sample by separating an upper substrate from the threshold power measuring pattern; a second step of supplying voltages on a gate pad on the lower substrate sample with sequentially increasing a voltage level by a predetermined unit by using an electrical device, and obtaining a threshold current and a threshold voltage by measuring currents at a drain pad whenever voltage increased by a predetermined unit is applied to the gate pad; and a third step of obtaining threshold power based on the threshold current and the threshold voltage, and thereby evaluating process conditions of the LCM.
    • 液晶显示模块(LCM)的工艺条件评估方法包括:获得阈值功率测量图案的第一步骤,LCD制造工艺中的单元接合状态的分析样本,以及通过分离下一个 上基板从阈值功率测量图案; 第二步骤,通过使用电气装置依次增加预定单位的电压电平,在下部基板样品上的栅极焊盘上提供电压,并且每当电压增加时,通过测量漏极焊盘处的电流来获得阈值电流和阈值电压 通过预定单元施加到栅极焊盘; 以及第三步骤,基于阈值电流和阈值电压获得阈值功率,从而评估LCM的处理条件。
