Abstract: An AMOLED doubled-sided display includes an OLED array layer that includes a plurality of top-emitting OLED units and a plurality of bottom-emitting OLED units arranged alternate with each other to form an array. Each of the top-emitting OLD units and the bottom-emitting OLED units has different thickness for respective anodes and cathodes, to realize the top-emitting characteristics of the top-emitting OLED units and the bottom-emitting characteristics of the bottom-emitting OLED units. As such, by designing an algorithm for a single IC to control image displaying, only a display panel and a control IC are sufficient to achieve double-sided displaying, and ensure an observer standing in front of the display panel will not see mirrored image or directional distorted image, as well as achieve low-cost and quality display result.

Abstract: A display panel is provided, and includes an array metal layer to form lines for transmitting a display signal to a display region, and a touch metal layer to form lines for transmitting a touch signal to a plurality of touch units. At least one touch signal interconnection region connects the lines of the array metal layer with the lines of the touch metal layer, so that a single touch and drive integrated chip can be used to process the display signal and the touch signal. Display noise caused by separation of a display chip and a touch chip in an original system architecture is thus avoided, and the number of components and the overall cost are reduced.

Abstract: The present disclosure proposes an OLED display device with FOD that includes an OLED display panel and a fingerprint recognition module disposed under the OLED display panel. Sub-pixels arranged in an array on a substrate are located in an effective display area of the substrate. A fingerprint recognition block is disposed in the effective display area. The fingerprint recognition module is disposed corresponding to the fingerprint recognition block. A number of TFTs in each of the sub-pixels located in the fingerprint recognition block is less than a number of TFTs in each of the sub-pixels outside the fingerprint recognition block. Through decreasing the number of the TFTs in each of the sub-pixels in the fingerprint recognition block, the number of films in the stack of the fingerprint recognition block is reduced. Accordingly, the transmittance of the fingerprint recognition block and the accuracy of fingerprint recognition are improved.
