Abstract

The embodiment of the invention relates to the field of OLED display, in particular to an OLED display device for improving the luminous efficiency of an organic light emitting layer. In the embodiment of the invention, an active organic light emitting diode OLED display device includes a light emitting module and a circular polarizer arranged on the light output side of the light emitting module.An organic light emitting layer in the light emitting module includes a polymer organic light emitting chromophore and a helical liquid crystal. The polymer organic light emitting chromophore is usedfor generating first linearly polarized light. The helical liquid crystal is used for converting the generated first linearly polarized light into circularly polarized light. The circular polarizer includes a phase difference compensation film and a polarizer layer. The phase difference compensation film is used for converting the circularly polarized light into second linearly polarized light. The light transmission direction of the polarizer layer is consistent with the vibration direction of the second linearly polarized light, and the polarizer layer is used for transmitting the second linearly polarized light out. The first linearly polarized light generated by the organic light emitting layer can be transmitted out completely, and thus, the luminous efficiency of the light emittinglayer is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of OLEDs, and in particular, to an OLED display device. Background technique [0002] The Organic Light-Emitting Diode (OLED) display device is currently a promising next-generation display technology. In order to eliminate the influence of ambient light on the display effect of the OLED display device and improve the contrast of images displayed by the OLED display device, a circular polarizing plate is usually attached to the packaging substrate of the OLED display device. [0003] In the prior art, since the natural light emitted by the organic light-emitting layer in the OLED display device passes through the circular polarizing plate, at least half of the light is absorbed by the circular polarizing plate, which causes the problem that the luminous efficiency of the organic light-emitting layer is reduced; moreover, the OLED display The luminous intensity of the device is another main facto...
