Abstract: A display panel and a display device are disclosed. The display panel includes bonding pads placed in the bonding region, a driving chip, and a conductive resin connected to the bonding pads. The driving chip comprises a first region close to the display region and a second region away from the display region. The second region has a plurality of driving terminals. The driving terminals and the corresponding bonding pads are one-by-one electrically connected to each other. The thickness of at least a part of the conductive resin corresponding to the first region is set to be greater than the thickness of the conductive resin corresponding to the second region to compensate the height difference caused by the raise of the driving terminals when the driving chip is bonded. This ensures that the driving chip could be well bonded on the display panel and avoids the shallow donor conductivity.

Abstract: The present invention provides a LTPS TFT substrate and a manufacturing method thereof. The LIPS TFT substrate of the present invention includes a metal layer formed on a channel zone so that the metal layer, a source electrode, and a drain electrode can be used as a mask to form LDD zones in a poly-silicon layer in order to save the mask needed for separately forming the LDD zones; further, due to the addition of the metal layer that is connected to the channel zone of the poly-silicon layer, the electrical resistance of the channel zone can be effectively reduced to increase a TFT on-state current. The LTPS TFT substrate manufacturing method of the present invention forms a metal layer on a channel zone at the same time of forming a source electrode and a drain electrode and uses the metal layer, the source electrode, and the drain electrode as a mask to form LDD zones in a poly-silicon layer so as to save the mask needed for separately forming the LDD zones thereby reducing the manufacturing cost and increasing throughput.

Abstract: The invention provides a touch driver circuit, by only using a select signal (Select) to control the operation of transport gates (TG1, TG2) to realize output of a valid pulse touch driver signal (TXH) and a constant low voltage signal (TXL). The circuit structure is simplified, and removes a plurality of elements and two control signals so as to reduce the layout space occupied by the touch driver circuit as well as reduced the border width of the touch display to realize narrow border design for touch display panel.

Abstract: A GOA circuit and an embedded touch display panel are provided. By providing an abnormity protection module in the nth-level GOA unit, the level of the scanning signal of the nth-level GOA unit is pulled up when the embedded touch display panel is powered off abnormally.
