Abstract: A display substrate, a method for manufacturing the same and a display device are provided. The display substrate includes a base substrate and a thin film transistor array arranged on the base substrate. Multiple pixels arranged in an array are provided in an effective display region of the display substrate. The effective display region includes an optical element arrangement region and other display regions, and a transmittance of the optical element arrangement region is larger than transmittances of the other display regions. In the optical element arrangement region, an optical element is arranged on a side of the base substrate away from the thin film transistor array, and the optical element emits and receives light that is transmitted through the display substrate.

Abstract: A pixel circuit includes a driving sub-circuit, a writing sub-circuit, a light-emitting device and a fingerprint information output sub-circuit. The writing sub-circuit is coupled to the driving sub-circuit, a first signal terminal and a data signal terminal, which is configured to write a data signal to the driving sub-circuit under control of a signal from the first signal terminal. The driving sub-circuit is coupled to an anode of the device and a first voltage terminal, which is configured to drive the device to emit light by using a voltage from the first voltage terminal, and provide a coupling capacitance to acquire fingerprint information. The fingerprint information output sub-circuit is coupled to the anode, a third signal terminal and a signal reading line, which is configured to output a signal acquired at the anode as the information to the line under control of a signal from the third signal terminal.

Abstract: A display panel, a manufacturing method thereof and a display device are provided. The display panel includes a plurality of functional layers arranged on a base substrate. A portion of at least one of the functional layers is removed to form a gap portion. The display panel further includes a light-transmissible structure including the gap portion and configured to allow a light beam to pass therethrough to an optical sensing element arranged at a position corresponding to the light-transmissible structure. An orthogonal projection of the gap portion onto the base substrate overlaps an orthogonal projection of the optical sensing element onto the base substrate.
