Problems solved by technology

In addition, since the touch sensing lines and other signal transmission lines (such as data lines, scan lines, and touch scan lines) are arranged in different layers, two different chips need to be arranged between the touch chip and the touch display panel. The flexible printed circuit board is used to respectively transmit and receive the touch scanning signal on the touch scanning line and the touch sensing signal on the touch sensing line in the touch display panel, and the assembly of the flexible printed circuit board will make possible Lower product yield

Embodiment Construction

[0029] Figure 1A It is a schematic diagram of a touch display device according to an embodiment of the present invention, Figure 1B shown as Figure 1A For the schematic side view of the touch display device of the embodiment, please also refer to Figure 1A and Figure 1B . The touch display device includes a first substrate 102, a second substrate 104, a plurality of data lines DL1, a plurality of scanning lines SL1, a plurality of touch sensing lines RL1, a display driver chip 106, a touch control chip 108 and a motherboard control unit 110. Wherein the first substrate 102 can be, for example, a thin film transistor substrate, and the second substrate 104 can be, for example, a color filter substrate, and as Figure 1B As shown, the second substrate 104 is disposed above the first substrate 102 . Further, the touch display device may also include a protective lens 116 (not shown in the figure to keep the illustration simple. Figure 1A Middle), which is disposed above ...

Abstract

A touch display apparatus is provided. Data lines are used to transmit display data signals or touch scan signals during different periods, wherein the data lines, the scan lines of the touch display apparatus and touch sensing lines of the touch display apparatus are disposed on a same substrate.

Description

technical field [0001] The present invention relates to an electronic device, and in particular to a touch display device. Background technique [0002] As far as a general flat display device is concerned, its image is composed of a two-dimensional pixel array. The driving mechanism can be divided into horizontal scanning lines and vertical data lines to drive the color and gray scale of each pixel. Traditional touch panels are, for example, resistive or capacitive. Measurements in two directions are used to determine whether there is a touch point and determine the position of the touch point. With the advancement of manufacturing technology, the touch panel has been successfully integrated into the display panel to achieve more effective and convenient control. [0003] Although the touch panel has been successfully integrated into the display panel, there is still room for improvement in the integration technology of the touch panel and the display panel. In the known...
