Abstract

The invention discloses a flexible display panel and a preparation method thereof. According to the flexible display panel, a display area, a combination area and a frame area are defined; the flexible display panel includes a flexible substrate, a protection layer, a semiconductor layer and a touch control layer, wherein grid electrode lead wires, earth wires, touch control inductive pickup electrode lead wires and a display area liner are arranged on the portion, in the display area, of the flexible display panel; first through holes are formed in the protection layer in the frame area, thegrid electrode lead wires are electrically connected with grid electrodes in the semiconductor layer through the first through holes. The flexible display panel has the advantages that traditional wiring positions are changed, hidden wiring design is adopted, the wires and the display area are designed at the same positions, in this way, extra space cannot be occupied, the non-display area is reduced, and the panel edge wiring width is effectively reduced.

Description

technical field [0001] The invention relates to the field of touch display devices, in particular to a flexible display panel and a preparation method thereof. Background technique [0002] In recent years, with the increasing application of consumer electronics products, more and more products are applied by combining the touch function with the display. Touch Technology has become a technology due to its convenient operation and high integration. development hotspot. [0003] Touch technology has developed rapidly in recent years, and a variety of touch technologies have been put into mass production. For the existing touch display panel, according to the location of the touch sensor (Touch Sensor), it can be divided into the type where the touch sensor is covered on the liquid crystal box (On Cell), and the type where the touch sensor is embedded in the liquid crystal box ( In Cell), and the touch sensor is attached to the display panel (Out Cell). [0004] With the ad...
