Problems solved by technology

Because if they overlap each other, the OLEDs will block the photodiodes and affect the photodiodes to receive light; if they are adjacent to each other, the flexibility of the design is limited, and it leads to a contradiction between improving the resolution of the OLED display and improving the resolution of the image sensor

Embodiment Construction

[0033] The present invention will be further described in detail below through embodiments in conjunction with the accompanying drawings.

[0034] Such as figure 2 As shown, an image transceiver device integrating OLED microdisplay, the device includes a silicon substrate, a photodiode on the silicon substrate and a transparent OLED on the silicon substrate. In one embodiment, the OLED emits visible light, and the photodiode is used to sense infrared light in the near-infrared band, that is, the device emits visible light images and receives near-infrared images. The photodiode is provided with a light-blocking layer in the image transceiver device, and the transmitted image and the received image are prevented from being adversely affected by visible light on the photodiode through the blocking effect of the light-blocking layer in the image transceiver device. The light-blocking layer 20 may have infrared light transmittance greater than 90% and cut-off visible light, and ...

Abstract

The invention discloses an image receiving and transmitting device integrated with a transparent organic light emitting diode (OLED) micro-display. The image receiving and transmitting device integrated with the transparent OLED micro-display comprises a base plate, a photodiode which is arranged on the base plate and used for sensing light and the transparent OLED which is arranged on the base plate and used for illuminating. An illuminating spectrum of the OLED is not overlapped with a sensitive spectrum of the photodiode. And the image receiving and transmitting device further comprises a light retaining layer which is arranged for the photodiode and only permeable for light which is pre-set and belongs to a wave band sensed by the photodiode. The invention further provides a manufacture method of the image receiving and transmitting device integrated with the transparent OLED micro-display. The light retaining layer is arranged, so that image transmitting and outside light can be blocked under the retaining effect of the retaining layer and image receiving is not affected.

Description

technical field [0001] The invention relates to OLED display technology, in particular to an image transceiver device integrating transparent OLED micro-display and a manufacturing method thereof. Background technique [0002] Organic light-emitting devices (OLEDs) have high luminous brightness, low driving voltage, fast response, no viewing angle limit, low power consumption, ultra-light and ultra-thin, can have any shape, color output is monochrome, white or near-infrared, and long life And other advantages, it has great application prospects in the fields of flat panel display, planar light source and so on. Combined with silicon-based CMOS drive circuits, functions such as signal acquisition, signal processing, and control can be integrated. [0003] refer to figure 1 In the example shown, photodiodes are embedded in an OLED microdisplay array for an image transceiver. Wherein, the silicon-based photodiode 7 is sensitive to near-infrared light, and the photodiode arra...
