Embodiment Construction

[0039] Please refer to FIG. 4(A), which shows an equivalent circuit diagram of the driving circuit of the input display according to the first embodiment of the present invention. As shown in FIG. 4(A), the drive circuit 200 includes a first gate line G in each readout pixel n-1 and the second gate line G n , and the first data line D m-1 and the second data line D m with the first and second gate lines G n-1 , G n Arranged across to form the readout pixels of the input display. In addition, in each readout pixel, the readout line 203 is arranged between the first and second data lines D m-1 、D m between, while the common line C p-1 Set on the first gate line G n-1 with the second gate line G n between. On the other hand, the circuit layout in each readout pixel can be divided into two parts, that is, the pixel unit 201 and the photoelectric unit 202 . In more detail, the pixel unit 201 further includes a pixel thin film transistor 2011, and the pixel thin film tran...

Abstract

The present invention provides an image sensor array and a liquid crystal display for increasing the readout time thereof. The image sensor array and liquid crystal display both comprise a substrate, a readout line disposed on the substrate, a first switch line and a second switch line both intersecting the readout line, a first position defined by the readout line and the first switch line, a second position defined by the readout line and the second switch line, and a sensor element disposed on the first position and separated from the second position, wherein the first switch line transmitting a first switch signal and the second switch line transmitting a second switch signal overlapped the first switch signal.

Description

technical field [0001] The invention relates to a drive circuit of a display, in particular to a circuit of a readout pixel of an input display and a driving method thereof. Background technique [0002] Because amorphous silicon materials have photoelectricity, and because the technology of photoelectric elements designed with these amorphous silicon materials is fully compatible with the technology of known active matrix (Active Matrix) liquid crystal displays, so, embedded these amorphous silicon The optoelectronic element is used as an input display, which is more competitive in cost than the known input display with a touch panel. [0003] In addition, the light transmittance of an input display with a touch panel will be reduced by at least 20% due to the touch panel; while the light transmittance of an input display using an amorphous silicon photoelectric element is only as high as that The photoelectric device in a pixel and the wiring method of the matching readou...
