Abstract

An on-cell Touch Screen Panel (TSP) Active Matrix Organic Light Emitting Diode (AMOLED) structure is provided. The on-cell TSP AMOLED structure includes an AMOLED, a display driver for driving the AMOLED, a display driver reinforcing material positioned at an upper part of the display driver, and a window positioned at an upper part of the display driver reinforcing material, wherein a resin or Optical Clear Adhesive (OCA) is applied between an upper surface of the display driver reinforcing material and a lower surface of the window. Therefore, separation and twist of a display driver reinforcing material can be prevented.

Description

technical field [0001] The invention relates to an active matrix organic light emitting diode (AMOLED) structure of an on-cell touch screen panel (TSP). More particularly, the present invention relates to an on-board touch screen panel AMOLED structure in which a resin is formed between the AMOLED and a window. Background technique [0002] In order to increase the display area while reducing the weight and thickness of the mobile terminal, touch screen technology is applied to the mobile terminal. Such touch screen technology is implemented using a touch screen panel (TSP) and a display such as a liquid crystal display (LCD) or an active matrix organic light emitting diode (AMOLED). There are more and more touch screen technologies utilizing AMOLED with high optical characteristics. [0003] figure 1 is a partial cross-sectional view showing the structure of a TSP AMOLED according to the prior art. [0004] refer to figure 1 , shows a TSP AMOLED structure 100 . A TSP ...
