Problems solved by technology

However, directly attaching the touch panel to the LCD panel will not only increase the thickness and weight of the entire display module, but also reduce the light transmittance.
In addition, too many transparent glass layers will not only cause the problem of too deep depth of field, but also greatly increase the weight of the entire display module

Abstract

The planar display with touch panel has its light guiding board of front light source used as the base board for touch panel and this can save a glass base board for touch panel.

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 ...
