[0055] Please refer to Image 6 , Image 6 A flow chart of a method for displaying lines drawn on a touch screen provided by the third embodiment of the present invention is shown. Also refer to figure 1 , the method may be a touch screen line drawing display process executed by the touch display device in the first embodiment. The method for displaying lines drawn on a touch screen may include the following steps 601-605:

[0056] Step 601 , use the touch sensor 111 to sense the user's touch operation on the display screen, generate a touch sensing signal according to the touch operation, and provide the generated touch sensing signal to the timing controller 101 .

[0057] Wherein, the touch operation is an action of a user's finger touching and drawing a line on the display screen.

[0058] Step 603, use the timing controller 101 to obtain the pixel coordinate information of the touch point, and then transmit the obtained pixel coordinate information to the signal conve...

Abstract

The invention provides a touch display device. The touch display device comprises a time schedule controller, a display screen, a signal converter and a memory. A touch sensor is arranged in the display screen and used for sensing touch operations, acting on the display screen, of a user and generating touch sensing signals according to the touch operations. The time schedule controller is used for obtaining touch parameters according to the touch sensing signals during an Nth frame, obtaining pixel coordinate information of touch points in an active display time slot during a (N+1)th frame, storing the obtained pixel coordinate information into the memory in a blanking time slot during the (N+1)th frame, and reading the pixel coordinate information stored into the memory in an active display time slot during a (N+2)th frame prior to transmitting the pixel coordinate information to the signal converter. The signal converter is used for converting the pixel coordinate information into display information and sending the display information to the display screen to display. The invention further provides a touch screen line drawing display method. By the touch display device and the touch screen line drawing display method, simple, rapid and accurate display of line drawing of the display screen can be achieved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display device and method. Background technique [0002] Now, many portable video electronic products, such as mobile phones, PDAs, game consoles, etc., are equipped with touch screens, which bring a lot of convenience to users' operations. Since the touch screen can replace many button operations, users only need to lightly touch the icons or text displayed on the touch screen to realize the operation of the device, so that many physical buttons can be saved, and the original user can save the cost of setting buttons. space. Especially for portable electronic products, the appearance of the touch screen can not only greatly reduce the number of physical keys, but also make the use of the touch screen to further enlarge the area of ​​the display screen. [0003] Usually, the operation on the touch screen is to click or draw a line, which is equivalent to the fu...
