Problems solved by technology

When the finger touches the wiring area, the touch wiring will generate a sensing signal. In addition, when the finger touches the edge of the screen display area, the touch wiring close to the display area will also be sensed, so that the touch wiring will appear. The signal volume of the corresponding touch electrode becomes larger, which reduces the touch accuracy and causes false alarms, so that the touch screen cannot work normally.

Abstract

The invention provides an integrated touch control organic light emitting diode display device comprising a display device which is arranged in a display area; a film packaging layer which covers the display device of the display area; a touch control device which comprises a touch control electrode which is arranged in the display area and a touch control wire which is arranged in a non-display area, wherein at least a part of touch control wire is arranged at the same layer of a first metal layer and a second metal layer; and a shielding electrode which covers the touch control wire and is insulated from the touch control device, wherein the shielding electrode is electrically connected with a fixed potential. Appearance of false alarm points can be prevented without additionally arranging the film layer so as to enhance the accuracy of touch control.

Description

technical field [0001] The present invention relates to the field of organic light-emitting display, in particular to an organic light-emitting diode display device with integrated touch control. Background technique [0002] With the increasing number of multimedia devices, people are talking more and more about touch screens, because as a new input device, touch screens have many advantages such as ruggedness, fast response, space saving, and easy communication. With this technology, the user can operate the host by lightly touching the display screen with a finger, thus making the human-computer interaction more straightforward. This technology greatly facilitates those users who do not understand computer operations. [0003] As organic light emitting display devices gradually enter people's lives, recently, touch technology is more and more applied to organic light emitting diode display devices. The On-Cell technology currently applied to the touch solution of the OLE...
