Organic electroluminescent display device and display device

Abstract

The present invention provides an organic electroluminescent display device and a display device. The organic electroluminescent display device comprises a pixel array, a packaging adhesive arranged around the pixel array, and a laser reflection piece used for reflecting the edge laser to the packaging adhesive. In this way, the laser reflection piece reflects the edge laser to the packaging adhesive, wherein the edge laser might burn pixels. As a result, pixels are prevented from being burned, and the utilization rate of the laser is increased at the same time. The energy is efficiently utilized and the energy loss is reduced. Meanwhile, the packaging performance of the glass cement is improved and the temperature gradient of the packaging adhesive can be reduced. The stress generation is avoided. The packaging capability and the mechanical quality of the device are improved.

Description

technical field [0001] The invention relates to the field of display, in particular to an organic electroluminescence display device and a display device. Background technique [0002] At present, rigid organic electroluminescent display devices (OLEDs) generally use glass glue as the packaging material, and laser sintering is used for effective packaging. Under the condition of a certain laser moving speed, the energy absorbed by the packaging area is related to the laser energy and the laser trajectory. . [0003] In actual production, the laser is used to irradiate the glass glue packaging area. At the corner of the OLED device, the packaging area is affected by the laser trajectory. The inner corner receives more energy from the laser irradiation than the outer corner, and the pixels here are most likely to be burned. Under lighting, refer to figure 1 , the edge corner pixel (Pixel) emits abnormal light; under the fluorescence microscope, refer to figure 2 , R / G / B ex...

Affect the quality of light emission of the device

In addition, in actual production, the greater the laser energy, the greater the temperature gradient of the glass glue after passing through the packaging area instantly, resulting in greater stress, which directly affects the mechanical quality of the device.

[0004] Therefore, the research on organic electroluminescent display devices needs to be in-depth
