Abstract
Description
technical field
[0001] The invention relates to a front light liquid crystal display combined with a touch panel, in particular to a light guide plate combining the touch panel with the front light source of the liquid crystal display. Background technique
[0002] Traditional reflective type liquid crystal displays generally use a front light as a light source, and then utilize a V-cut of a light guide panel to guide the light source into the liquid crystal display. Such as figure 1 As shown, a substrate 100 serving as the lower glass substrate of a reflective liquid crystal display has a matrix thin film transistor 102 thereon, a protective layer 104 , and a reflective layer 106 located on the protective layer 104 . An upper glass substrate 114 is located on the reflective layer 106 . A retardation plate 116 and a polarizing plate (polarizing plate) 118 are sequentially disposed on the upper glass substrate 114 , and a color filter 112 and a transparent conductive layer ...
