High-accuracy narrow bezel embedded flat display touch structure

The present invention relates to a structure having a touch panel, and more particularly to a high-accuracy narrow bezel embedded flat display touch structure.

Modern consumer electronic devices are often equipped with a touchpad as one of their input devices. The touchpad can be divided into resistive, capacitive, sonic, and optical types according to different sensing principles.

The technical principle of the touch panel is to detect the voltage, current, sound wave or infrared light according to different sensing methods when the finger or other medium touches the screen, thereby measuring the coordinate position of the touch pressure point. For example, the resistance type is to use the potential difference between the upper and lower electrodes to calculate the position of the pressure point to detect the touch point. A capacitive touch panel detects a change in capacitance from a generated current or voltage by utilizing a change in capacitance generated by electrostatic coupling between a transparent electrode arranged and a human body.

With the popularity of smart phones, the demand for multi-touch technology is increasing. At present, multi-touch is mainly realized by Projected Capacitive touch technology.

Projected capacitive technology is mainly through double-layer indium tin oxide Indium Tin Oxide (ITO) forms a matrix of interlaced sensing units to detect accurate touch positions. The basic principle of the projected capacitive touch technology is based on capacitive sensing. By designing a plurality of etched indium tin oxide electrodes, the array has different planes and transparent lines perpendicular to each other to form an X- and Y-axis drive. line. These wires are controlled by the controller, which sequentially feeds the detected capacitance value changes to the controller.

FIG. 1 is a schematic diagram of a conventional mutual capacitance sensing. The sensing conductor lines 110, 120 on the touch panel structure 100 sensed by the conventional mutual induction capacitance (Cm) are arranged along the first direction (X) and the second direction (Y). There is a mutual induction capacitance (Cm) 160 between the sensing conductor line 110 arranged in the first direction (X) and the sensing conductor line 120 arranged in the second direction (Y), and the mutual induction capacitance (Cm) 160 is not a physical capacitance, and the edge thereof is The mutual induction capacitance (Cm) between the sensing conductor line 110 arranged in the first direction (X) and the sensing conductor line 120 arranged in the second direction (Y).

When the touch sensing is to be performed, an internal driver (not shown) of the control circuit 131 on the flexible circuit board 130 drives the sensing conductor line 110 arranged in the first direction (X) for the first time period T1, and uses the same. The voltage Vy_1 charges the mutual induction capacitor (Cm) 160. During the first time period T1, all the sensors (not shown) inside the control circuit 131 sense all the second direction (Y) arranged on the sensing conductor line 120. The voltage (Vo_1, Vo_2, ..., Vo_n) is used to obtain n data, that is, after m driving cycles, m×n data can be obtained.

The mutual sensing capacitor (Cm) is mainly used to form a matrix of interlaced sensing units with double-layer Indium Tin Oxide (ITO) on the display panel to detect an accurate touch position. . therefore Will increase manufacturing procedures and costs. At the same time, when the sensing conductor 120 transmits the sensed signal to the control circuit 131 on the flexible circuit board 130 when performing the touch sensing, the side line 150 of the panel 140 needs to be routed to connect to the flexible circuit board. 130. This design will increase the width of the touch panel border and is not suitable for the narrow bezel design trend.

In view of the above problems, the In-Cell Touch technology integrates the touch components into the display panel, so that the display panel itself has a touch function, so that no additional process of assembling or assembling with the touch panel is required. The In-Cell Touch technology is provided with an ITO transparent sensing electrode layer or an optical sensing element on the upper glass substrate or the lower glass substrate of the display panel. However, this not only increases the cost, but also increases the process procedure, which leads to a decrease in process yield and a rise in process cost, and a need for a stronger backlight with a lower aperture ratio, which also increases power consumption. Therefore, there is still room for improvement in the conventional flat display touch structure.

The main purpose of this creation is to provide a high-accuracy narrow-frame in-line flat-panel display touch structure, which only needs to be connected on one side, which can increase the amount of capacitance change between conductor blocks, and use less The voltage can drive the conductor block line and improve the accuracy of contact point detection.
