Driving method, driver circuit and design method of driver circuit for in-cell touch display panel
First Claim
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.

Abstract
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.
