Abstract: The present invention provides an OLED display panel. The display panel includes a plurality of sub-pixels arranged in an array. Each of the sub-pixels comprises a base substrate, a TFT layer, a flat layer, a first electrode, a pixel defining layer, a light emitting layer, a transparent second electrode, and an encapsulation layer. A portion of at least one of the flat layer and the pixel defining layer is formed by a black shielding material. The OLED display panel can be prevented from reflecting ambient light without improving the light extraction efficiency, thereby improving the viewing experience of the OLED display panel by the arrangement of a portion of at least one of the flat layer and the pixel defining layer is formed by a black shielding material.

Abstract: An OLED device and a packaging method of OLED are provided. The OLED device includes substrate, packaging layer, light-emitting layer, and packaging strip. The light-emitting layer is positioned between substrate and packaging layer. The packaging strip is packaging edge of packaging layer and edge of substrate. The light-emitting layer is enclosed in a space surrounded by substrate, packaging layer and packaging strip. It encloses a space for light-emitting layer by substrate, packaging layer, packaging strip according packaging strip enveloping periphery of upper and lower surface of substrate and packaging layer. Also, positioning sealant between packaging strip and substrate, and between packaging strip and packaging layer, it provides better package effectiveness therebetween. Therefore, it is elongating the path which enters from sealant position to inner of OLED device by moisture, oxygen and so on.

Abstract: A touch display panel and a display device are disclosed. The touch display panel includes a first substrate, a second substrate, a first solder pad, a second solder pad and a touch sensing layer. The first substrate is defined with a display region and a non-display region. In the present invention, the first solder pad is disposed at a substrate having the touch sensing layer. That is, the first substrate is provided with a non-display region having the second solder pad. A wider black masking region for the first solder pad and corresponding trace region is not required so that an edge frame of the display device can be reduced, which is beneficial for a narrow-frame design of the display device.

Abstract: A double-sided OLED packaging structure is provided and has an upper plate and a lower plate. Edges of each of the upper plate and the lower plate has a bending structure disposed thereon. A packaging glue is disposed on an inner side of the bending structure, such that two light emitting display portions are corresponding to and connected to each other by the packaging glues and the bending structures. Therefore, the double-sided OLED packaging structure can protect an organic light-emitting layer from high-temperature damage and prolong the display life by disposing the packaging glue on a side part of the packaging cover and thus away from a light-emitting surface.

Abstract: The present disclosure relates to a manufacturing method of display panels. The method includes providing at least two glass substrate having a predetermined dimension, configuring the glass substrate to be spaced apart from a supporting substrate, configuring a bonding area on the glass substrate, conducting a cell-formation process or a package process of the display panel, and stripping the supporting substrate. In this way, the thicker supporting substrate is configured to support the glass substrate so as to avoid two ends of the thinner glass substrate from dropping and curing, which enhances the convenience and the precision of the manufacturing process of the display panel.

Abstract: Disclosed are an OLED display unit and a method for manufacturing the same. The OLED display unit includes a first electrode, a light emitting material layer, a second electrode, and an auxiliary electrode. The auxiliary electrode is provided below the second electrode, and is formed prior to the light emitting material layer. The auxiliary electrode is connected with the second electrode to reduce impedance of the second electrode. When the OLED display unit is used, a voltage drop resulted from a wire resistance of a cathode in a large sized display device can be reduced or eliminated, and increased power consumption caused by uneven light emission can be avoided.
