Problems solved by technology

[0004] However, since the light-sensing display proposed by Boer et al. must use a charge readout amplifier to charge the light-emitting pixels, the signal on the readout line will be easily disturbed, so that the As a result, the signal to noise ratio (S / N ratio) of the signal on the readout line becomes lower, and the light-sensing display proposed by Boer et al. The position touched by the touch panel

Embodiment Construction

[0069] figure 1 It is a partial cross-sectional schematic diagram of the touch panel 100 according to the first embodiment of the present invention. Please refer to figure 1 The touch panel 100 includes an active element array substrate (such as a TFT array substrate) 101 , an opposite substrate 103 , and a liquid crystal layer 105 . The active device array substrate 101 includes a first substrate Sub1 and a plurality of pixel structures, and the pixel structures can be arranged in an array on the first substrate Sub1.

[0070] In this embodiment, at least one first pixel structure Pix in every M×N pixel structure has a first display area and a first sensing area, wherein M and N are positive integers, and the remaining pixel structures can only It is enough to have the first display area, but it is not limited thereto. For example, assuming that the resolution of the touch panel 100 is 1024×768, it can be assumed in this embodiment that each 6×4 pixel structure has at leas...

Abstract

The present invention provides a touch panel and a portable electronic device having the touch panel. The touch panel includes: multiple pixel circuits arranged in an array mode, wherein at least onefirst pixel circuit of each M*N pixel circuits includes: an active component, having a gate, a source cathode and a drain, the gate is electrically connected with the drain, the source cathode is electrically connected with a read wire; and a switch, one end is electrically connected with the second drain, the other end is electrically connected with the scanning wire. When the switch is turned on, the region of showing M*N pixel circuits constitution is the touched position of the touch panel, and M, N are positive integers. The touch panel of the invention accurately judges the touching position of the touch panel by users only by judging the dividing voltage value between the reference capacitor of the pixel configuring with a sensing region and the sensing capacitance whether changed or not, or only by judging the switch of the pixel configuring with the sensing region whether turned on or not.

Description

technical field [0001] The present invention relates to a portable electronic device, and in particular to a portable electronic device with a touch panel. Background technique [0002] Due to the rapid development of today's technology, portable electronic devices (such as PDA mobile phones) have gradually become one of the electronic products that modern people rely on. Generally speaking, today's PDA mobile phones are equipped with a touch panel (touch panel) function, so that users can directly operate the PDA mobile phone through a stylus or fingers. However, since the touch panel of the current PDA mobile phone is generally a push-type touch panel composed of a display (such as a thin film transistor liquid crystal display, TFT-LCD) and a touch panel, it is made in this way. The traditional touch panel will cause the disadvantages of reducing the brightness of the display and increasing the thickness of the original display. [0003] Therefore, in view of the current...
