Problems solved by technology

[0005] It can be seen from the structure of the main capacitive touch screens mentioned above that the existing capacitive touch technology needs to combine the touch sensor and / or cover lens with the liquid crystal display panel through a full lamination process. However, the process is cumbersome, the cost is high, and the production efficiency is low

Abstract

A touch display panel comprises a first substrate and a second substrate opposite to the first substrate, wherein the first substrate is located above the second substrate to enable he first substrate to be located on one side close to a user, grid lines and data lines are formed on one side of the first substrate close to the second substrate and intersected to form multiple pixel units arranged in a matrix mode, a pixel electrode and an oxide thin-film transistor are arranged in each pixel unit, the pixel electrodes are connected with the grid lines and data lines through the oxide thin-film transistors, at least one portion of the grid lines concurrently serves as one of touch driving lines and touch sensing lines, at least one portion of the data lines concurrently serves as the other one of the touch driving lines and the touch sensing line, the grid lines and the data lines receive image scanning signals and data signals at an image display stage for image display and receives touch driving signals and output touch sensing signals at a touch detection stage for touch detection.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display panel and a touch display device. Background technique [0002] With the development of the information age and the acceleration of the pace of life, touch technology has gradually replaced the traditional mouse and keyboard due to its humanized design and simple and fast input, and is widely used in various electronic products. Such as: mobile phones, computers, personal digital assistants, etc. According to different sensing principles, touch panels are divided into: resistive, capacitive, optical, acoustic, and electromagnetic. Since the capacitive touch display panel has the advantages of fast response, high sensitivity, good reliability and high durability, the capacitive touch display panel has been widely used at present. [0003] The capacitive touch screen mainly includes a protective glass (Cover Lens) and a touch sensor (Touch Sensor). There...
