Abstract

The invention discloses an upward lighting transparent touch screen with organic light emitting diode, wherein the screen comprises a baseboard, an upper cover plate, an organic light emitting diode display element, a capacitor touch controller, and a seal layer. The diode is laminated on the baseboard, the controller is laminated on the upper cover plate, and the seal layer is combined with the baseboard and the upper cover plate to seal the diode and the controller between the baseboard and the upper cover plate. The controller forms a first transparent conductive layer, an insulation layer, a second transparent conductive layer and an electromagnetic shield layer on the upper cover plate, while the shield layer can effectively reduce the electric field interface between the diode and the controller. The invention can accurately and sensitively sense touch operation, with wide application in screens.

Description

technical field [0001] The present invention relates to a transparent touch screen, in particular to a transparent touch screen (touch screen) of an up-emitting organic light emitting diode (Organic Light Emitting Device; OLED). Background technique [0002] Currently, OLED display devices can be classified into two types of light emitting types: bottom emitting type and upward emitting type. Since the light emitted by the bottom-emitting structure will be shielded by the thin-film transistor (TFT) structure on the substrate and affect the aperture ratio, the upward-emitting structure is an effective solution to solve the light-emitting area ratio of traditional active light-emitting diode display devices. Countermeasures. [0003] Touch screen is currently the most simple, user-friendly and space-saving input tool. It has been widely used in tourist guide systems, automatic teller machines, palmtop computers, point-of-sale terminals and industrial control systems. [0004...
