Abstract

The present invention provides a touch screen. The touch screen comprises a touch panel, wherein the touch panel is provided with a display area and a non-display area; a plurality of capacitance touch electrodes are arranged on the touch panel and comprise a plurality of electrodes in parallel arranged in a first direction and a plurality of electrodes in parallel arranged in a second direction; the first direction and the second direction are mutually crossed; at least one part of the capacitance touch electrodes are arranged in the display area, and at least one part of the capacitance touch electrodes re shared as an electromagnetic touch electrode; a first additive electrode is further arranged on the touch panel, is also arranged in the non-display area and is arranged in parallel relative to the capacitance touch electrodes in the first direction; and the first additive electrode is an electromagnetic touch electrode. According to the touch screen and the display apparatus, the additive electrode is arranged in the non-display area, an effective detection range to a touch pen on the touch panel is expanded, and the characteristic absence of the edge of the touch panel in the prior art is improved.

Description

technical field [0001] The present application relates to a touch screen, and in particular, to a touch screen and a display device including the touch screen. Background technique [0002] The traditional electromagnetic-capacitive integrated touch screen is assembled by three separate systems, including LCD display panel, electromagnetic touch panel and capacitive touch panel. The capacitive touch panel and the electromagnetic touch panel are respectively arranged above and below the LCD display panel. These three systems output their respective signals without interfering with each other. This traditional electromagnetic-capacitance integrated touch screen has disadvantages such as high cost, low module strength, and many input / output (I / O) interfaces. [0003] For this reason, an electromagnetic capacitive integrated touch screen that shares capacitive touch electrodes is proposed. figure 1 The capacitive touch screen on which the electromagnetic capacitive integrated...
