A mask plate group of an organic light emitting diode (OLED) panel, a cathode evaporation method thereof and an OLED panel are provided. The OLED panel includes a display area having an imaging area, and the mask plate group includes a first mask plate and a second mask plate. The first mask plate includes a common mask opening area. The common mask opening area covers an entire of the display area. The second mask plate includes a special-shaped mask opening area. The special-shaped mask opening area covers all the display area except the imaging area.

OLED panel, having cathode disposed on pixel opening evaporation method thereof, and mask plate group thereof having mask plate corresponding to pixel opening

A display panel, comprising a first display portion and at least one curved second display portion disposed on at least one side of the first display portion. The display panel further comprises: an array substrate; and a planarization layer, an anode layer, a pixel definition layer, a light-emitting layer, a cathode layer and an encapsulation layer sequentially disposed on the array substrate. The planarization layer comprises a plurality of first surfaces and a plurality of second surfaces, each of the plurality of second surfaces comprises a first end arranged close to the first display portion and a second end arranged away from of the first display portion, a vertical distance between the first end and a bottom of the planarization layer is less than a vertical distance between the second end and the bottom of the planarization layer.

Display panel and manufacturing method thereof

A mask and an encapsulating method of a display panel are provided. The mask is configured to encapsulating the display substrate. The display substrate includes a display area, a bonding area, and a notch. The mask includes an opening area and a non-opening area. A size of the mask is determined by a size of the used display substrate. A corresponding size of the display substrate adapts the mask having the corresponding size. The present disclosure can effectively prevent line damage and also improve substrate yield.

Mask and encapsulating method of display panel

A mask component includes a first mask plate and a second mask plate, and the first mask plate includes a first shield region, a first open region disposed in the first shield region, an electronic component shield region disposed in the first open region, a connecting shield region disposed in the first open region. The electronic component shield region is connected to the first shield region by the connecting shield region. The connecting shield region includes a first connecting shield region disposed on one side of the electronic component shield region and a second connecting shield region disposed on another side of the electronic component shield region, and the first mask plate is configured to evaporate a common electrode to obtain a first region of the common electrode.

Mask component

An organic light-emitting diode (OLED) display panel and a manufacturing method thereof are provided. The OLED display panel includes an array substrate and a cathode structure. The cathode structure includes a metal film layer. The metal film layer includes a first metal film layer and a second metal film layer. The first metal film layer is positioned within the first active area and the second metal film layer is positioned within the second active area. Different regions of the metal film layer in the cathode structure are adjusted to different thicknesses, so that different regions have different light transmittances, which is beneficial to increase screen-to-body ratio.

Organic light-emitting diode display panel, manufacturing method thereof, and organic light-emitting diode display device

The present invention provides a mask plate, including a shielding region and an opening region. Wherein the shielding region surrounds the opening region, a shape and location of the opening region corresponds to a film forming region and a portion of a bonding region of a sub-pixel such that a thin film encapsulation material which passes the opening region covers the film forming region and the portion of the bonding region of the sub-pixel, and revealing a FPC region and a testing port. Accordingly, the traces of the boning region on the sub-pixel can be covered and protected by the thin film in order to solve the problem that the traces are damaged or broken so that a lighting yield rate is decreased.

Mask plate and thin-film encapsulation method

A wheel cutter for cutting a flexible glass substrate and a cutting method thereof are provided and the wheel cutter has a first disk surface and a second disk surface; a circumferential cutting edge formed by the first disk surface and the second disk surface extending outwardly and intersecting each other; a central shaft hole; and a hollow region connected to the central shaft hole; a plurality of recesses distributed on the circumferential cutting edge and communicating with the hollow region; wherein the hollow region is a double cone structure configured to allow cleaning an inside of the wheel cutter.
