Researchers develop display screens with biometric sensor capabilities

Traditional display screens like those built into smartphones require extra sensors for touch control, ambient light, and fingerprint sensing. These additional sensors increase the cost and design complexity, limiting the development of screens with a large screen-to-body ratio.

Researchers at Linköping University, Sweden, however, have introduced a multifunctional display that can perform all of these roles simultaneously without the need for additional sensors. This not only simplifies the display structure but also enhances its functionality. The research paper showcases an …
