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.
