Display device having touch function and terminal equipment including display device

Abstract

The invention discloses a display device having a touch function. The display device comprises a touch sensing module (2), a touch display controller (3) and a display module (4); the touch display controller (3) is used for receiving an image signal and a control signal sent by a host, controlling the display module (4) to display, and controlling the touch sensing module (2) to perform touch identification and send an identified signal to the host; and, after receiving a small keyboard input window triggering signal sent by the host, the touch display controller (3) controls the display module (4) to display an input window with a small keyboard, and controls the touch sensing module (2) to detect touch position information of a small keyboard area, match the touch position information with small keyboard position information to obtain small keyboard input data, and then transmit the small keyboard input data to the host (5). The display device having the touch function can be completely compatible with an existing entity password keyboard; international and domestic standard requirements can be satisfied; and existing equipment can also be replaced more easily.

Description

technical field [0001] The present invention relates to the field of touch screens, in particular to a display device with a touch function and a terminal device including the device, in particular to a touch display device with a password input function and an ATM device including the touch display device.

When using an ATM device, there is an inevitable process of entering the password. The password input of the current ATM device has been using a special keyboard. time, good confidentiality, the old keyboard input needs to be eliminated

Although the current ATM equipment is equipped with a touch screen on the display screen for selection operation, but at the same time, the selection operation buttons are repeatedly set on the side of the display screen, and the touch screen becomes a dispensable burden; the traditional touch screen can be used For password input, but it depends on the host, the function of password input is realized by the host and the touch screen, that is: the host is responsible for generating the password keyboard and controlling the display display, the touch screen is responsible for input, and the exchange between the host and the touch screen is in the process of password input The information does not meet the security specification requirements of existing password input equipment, such as Q / CUP007.6-2010 UnionPay card acceptance terminal security specification

Moreover, since the ATM mainframe involves currency circulation, a high level of security is required, and ordinary touch screens cannot be used to input passwords, and there will be flaws in confidentiality
