Abstract

The invention provides a display substrate, a display panel, a touch display device and a manufacturing method thereof. The display substrate includes a display area and a non-display area, and a plurality of first binding pins and a plurality of second binding pins are arranged in the non-display area. Binding pins; the first binding pins are used for binding with the flexible circuit board, and some of the first binding pins are connected to the signal lines set in the display area, so that the signal lines can pass through the first binding pins and connect with the flexible circuit board. The driver integrated circuit on the flexible circuit board is connected; the second binding pin is used for binding with the touch panel, and the second binding pin is connected with another part of the first binding pin in a one-to-one correspondence, so that the touch panel The touch electrodes can communicate with the touch integrated circuit on the flexible circuit board through the second binding pin and the first binding pin. Using the display substrate can reduce the binding steps in the binding process of the touch display device with the display substrate, and can also enable the touch display device with the display substrate to realize an ultra-narrow frame.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate, a display panel, a touch display device and a manufacturing method thereof. Background technique [0002] The plug-in touch display device is to stick the plug-in touch screen on the outside of the display panel. In the prior art, when carrying out the bonding (bonding) process of the plug-in touch display device, firstly, it is necessary to connect the display panel to a Chip On Flex (Chip On Flex, or Chip On Flex) film provided with a driver IC (Driver IC). On Film (referred to as COF) and the main flexible circuit board (Main Flexible Printed Circuit, referred to as MFPC) binding, the touch panel and the touch flexible circuit board (Touch Flexible Printed Circuit) equipped with a touch integrated circuit (Touch IC), TFPC for short), then attach the touch panel to the display panel, and finally, bind the main flexible circuit board to the touch f...
