Abstract

The embodiment of the invention provides a touch control display panel, a device and a making method. The touch control display panel comprises a light emitting unit array substrate, a packaging substrate, at least one fingerprint identification unit and a touch control electrode, wherein the light emitting unit array substrate comprises a substrate and multiple light emitting units located at one side of the substrate; the multiple light emitting units are arranged in an array mode along a first direction and a second direction parallel with the plane of the substrate, and the first direction and the second direction are crossed; the packaging substrate is located at one side, away from the substrate, of the multiple light emitting units; the at least one fingerprint identification unit is located at one side, close to the light emitting unit array substrate, of the packaging substrate, the fingerprint identification unit comprises a thin film transistor and a shading layer, vertical projection of the shading layer on the packaging substrate covers vertical projection of a channel area of the thin film transistor on the packaging substrate; and the touch control electrode is formed by grid-shaped metal wiring and is arranged in the same layer as the shading layer. the technological process of the touch control display panel is simplified, and the touch control display panel is thinned.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display panel, a device and a manufacturing method. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display is a self-luminous display. Compared with LCD (liquid crystal display, liquid crystal display), OLED display does not require a backlight source, so OLED display is thinner and lighter. In addition, OLED display is also It has the advantages of high brightness, low power consumption, wide viewing angle, high response speed, and wide operating temperature range, and is increasingly used in various high-performance display fields. [0003] On the other hand, since fingerprints are inherent to each person, they are unique. With the development of technology, a variety of display devices with fingerprint recognition functions appear on the market, such as mobile phones, tablet computers, and smart wearable device...
