摘要： A liquid crystal display (10) is provided with a source (23, Fig. 2) of backlighting (24) which augments reflected (25) incident light to provide increased contrast. A liquid crystal cell (17) which does not contain dye, but becomes clear when a field is applied, is sandwiched between a liquid crystal cell (14) with a dye and the source (23). The cell without dye is electrically connected so that when the front liquid crystal cell (14) is turned ON to make selected portions of it transparent, the back liquid crystal cell (17) is OFF so that corresponding portions of it are highly reflecting. No voltage is allowed to be applied across nonselected portions of the front liquid crystal and a voltage is applied across corresponding nonselected portions of the back liquid crystal making the nonselected portions of the back liquid crystal clear, producing a display of high contrast. The source (23) at the rear of the back liquid crystal cell is a clear plastic wedge which is edge lighted. The edge lighted wedge only appears bright in the areas where the voltage on the back liquid crystal cell (17) is OFF or not applied thereto.

摘要翻译：液晶显示器（10）设置有背光（24）的源（25，图2），其增加反射（25）入射光以提供增强的对比度。不含染料的液晶单元（17）被夹在具有染料的液晶单元（14）和源（23）之间，当施加场时变得清晰。没有染料的电池电连接，使得当前部液晶盒（14）导通以使其选择的部分透明时，背面液晶单元（17）关闭，使得其对应的部分反射高。不允许在前液晶的非选择部分上施加电压，并且在背面液晶的相应非选择部分上施加电压，使背面液晶的非选择部分清晰，产生高对比度的显示。背面液晶单元后部的源（23）是边缘点亮的透明塑料楔形物。在背面液晶单元（17）上的电压关闭或不施加到其上的区域中，边缘点亮的楔形物仅显示明亮。
