LCD Driver

指驱动液晶panel的回路或IC。以matrix来表示，可分为行电极Driver与列电极Driver 英：

LCD Driver is for driving LC panel circuit or IC. In matrix terms, it can be differentiated into column electrode Driver and row electrode Driver.

LCD Projector

将小型的液晶面板（LCD panel）放大投影而取得大画面之方式。可分为使用3片单色TFT的3板式及使用1片彩色TFT的单板式。从价格、重量来看，单板式较有利。3板式系利用二色镜（dichroic mirror）自光源的光中取出光的三原色后进行彩色之显示。分为rear pro 与 front pro二种方式。就亮度来说，rear pro较有利。 英：

A method to magnify and project a smaller-sized LCD panel into a bigger display. This can be achieved by using either three single-color TFT or one color TFT. From a price and weight standpoint, it should be more beneficial to use the one color TFT method. The three single-color TFT method uses a dichroic mirror to display the colors from external light sources. It is divided into rear projector and front projector. In terms of brightness, rear projector has more advantages than front projector.

Line defect

出现于水平及垂直之线状的显示缺陷。 英：

Line defect is a display defect which appears in horizontal or vertical lines.
