Abstract

The present invention provides a panel and a panel preparation method. The panel includes: a substrate including a first surface and a second surface arranged oppositely; a thin film transistor array disposed on the first surface, the thin film transistor array including a plurality of thin film transistors distributed in a matrix; the first an insulating layer, disposed on the thin film transistor array; a common electrode layer, disposed on the first insulating layer, and the common electrode layer includes a plurality of sensing units distributed in a matrix, and adjacent sensing units A gap is arranged between them; a second insulating layer is arranged on the common electrode layer and fills the gap; a shielding layer is arranged on the second insulating layer and is arranged corresponding to the gap; the shielding layer and the The common electrode layers are electrically connected.

Description

technical field [0001] The invention relates to the display field, in particular to a panel and a method for preparing the panel. Background technique [0002] With the increasingly fierce competition in the smart phone market, touch-display integration (referred to as touch-display integration) products has ushered in a new round of competition. In cell technology is regarded as a high-end technology in this field and is widely sought after. The so-called in cell technology refers to embedding touch panel functions into liquid crystal pixels. In the current self-capacitive touch technology solution, the common electrode is usually cut to form a plurality of sensing units (sensors) distributed in a matrix, and there are cutting slits between adjacent sensing units. When the electric field generated by the data line (data line) passes through the cutting slit between the sensing units, it will affect the corresponding liquid crystal at the cutting slit, disturbing the steer...
