Abstract

Official abstract text for this publication.

The invention provides a driving method, driver circuit and designing method of driver circuit for in-cell touch display panel. The driving method comprises: Step 10: connecting all horizontal scan lines of the touch display panel to a first GOA circuit, the first GOA circuit performing display scanning according to a preset timing sequence; Step 20: after completing each time of TP scanning according to preset timing sequence, a first horizontal scan line in a following scanning according to preset timing sequence still connected to a second GOA circuit, the second and first GOA circuits synchronously performing display scanning to the first horizontal scan line. The driving method, driver circuit and design method of driver circuit for in-cell touch display panel provided by the invention solve the dark line problem appearing in time-sharing scanning between display and TP terms for in-cell touch display panel, and improve display quality.

First claim

Opening claim text (preview).

What is claimed is: 1. A driving method for in-cell touch display panel, which comprises: connecting all horizontal scan lines of the touch display panel to a first gate on array (GOA) circuit, and the first GOA circuit performing display scanning according to a preset timing sequence; and after completing each time of touch panel scanning according to the preset timing sequence, a first horizontal scan line in a following scanning according to the preset timing sequence being still connected to a second gate on array (GOA) circuit, the second GOA circuit and the first GOA circuit synchronously performing display scanning to the first horizontal scan line, wherein the first horizontal scan line is connected to both the first and second GOA circuits, while remaining ones of the horizontal scan lines are connected to the first GOA circuit only. 2. The driving method for in-cell touch display panel as claimed in claim 1 , wherein the touch display panel is a hybrid in-cell LCD. 3. The driving method for in-cell touch display panel as claimed in claim 1 , wherein the touch display panel is a full in-cell LCD. 4. The driving method for in-cell touch display panel as claimed in claim 1 , wherein the first GOA circuit and the second GOA circuit are located respectively at two opposite sides of the touch display panel. 5. The driving method for in-cell touch display panel as claimed in claim 1 , wherein the first GOA circuit and the second GOA circuit have a thrust passing simulation confirmation in advance. 6. A driver circuit for in-cell touch display panel, which comprises: a first gate on array (GOA) circuit, and a second gate on array (GOA) circuit; the first GOA circuit being connected to all horizontal scan lines of the touch display panel, and performing display scanning according to a preset timing sequence; and after completing each time of touch panel scanning according to the preset timing sequence, a first horizontal scan line in a following scanning according to the preset timing sequence being still connected to the second GOA circuit, the second GOA circuit and the first GOA circuit synchronously performing display scanning to the first horizontal scan line, wherein the first horizontal scan line is connected to both the first and second GOA circuits, while remaining ones of the horizontal scan lines are connected to the first GOA circuit only. 7. The driver circuit for in-cell touch display panel as claimed in claim 6 , wherein the first GOA circuit and the second GOA circuit are located respectively at two opposite sides of the touch display panel. 8. The driver circuit for in-cell touch display panel as claimed in claim 6 , wherein the first GOA circuit and the second GOA circuit have a thrust passing simulation confirmation in advance.
