BOE and Chengdu BOE apply for display panel-related patents, enabling in-screen fingerprint recognition without affecting pixel density

On April 4, the National Intellectual Property Administration’s information shows that Beijing Oriental Yuhong? Technology Group Co., Ltd., Chengdu BOE Optoelectronics Technology Co., Ltd. have applied for a patent titled “Display Panel and Driving Method Thereof, and Display Apparatus.” The application publication number is CN121772555A, the application number is CN202411389108.4, the publication (announcement) date is March 31, 2026, the application date is September 30, 2024. The inventor is Yu Tiancheng. The patent agent is Beijing Lvzhih? Intellectual Property Agency Co., Ltd., and the patent agent is Chen Boch?ing. The classification numbers are H10K59/40, H10K59/131, H10K59/38, H10K59/35, H10K59/12, G09G3/30, G09G3/3208, G06F3/041, G06V40/13.

The patent abstract shows that a display panel includes an emissive light-emitting device and an optical-response light-emitting device. The wavelength of the emitted light of the emissive light-emitting device is greater than the wavelength of the emitted light of the optical-response light-emitting device. The emissive light-emitting device and the optical-response light-emitting device emit light under a forward bias of a forward driving circuit. When the light emitted by the emissive light-emitting device is reflected to the optical-response light-emitting device, the optical-response light-emitting device generates a photocurrent under a reverse bias of a reverse driving circuit, causing the optical-response light-emitting device to turn on, thereby enabling fingerprint recognition. The optical-response light-emitting device not only has a light-response function, but also has a normal display function. Therefore, while realizing in-screen fingerprint recognition, this display panel will not affect pixel density, and can be applied to high pixel density display panels. A driving method for the above display panel is also provided, as well as a display apparatus including the display panel.
