    Abstract: Disclosed are to a pixel circuit, a method for driving the pixel circuit and a display panel. The pixel circuit includes a data write module, a storage module, a drive module and a light emitting device. The drive module includes a first control terminal and a second control terminal. The data write module is configured to write, at a data write stage, a data signal into the first control terminal of the drive module, the storage module is configured to maintain a potential of the first control terminal, the second control terminal is electrically connected to a pulse-width modulation (PWM) signal input terminal of the pixel circuit, and is configured to control the drive module to provide discontinuous drive current according to a PWM signal from the PWM signal input terminal at a light emission stage, and the light emitting device emits light in response to the discontinuous drive current.

    Abstract: A glucose sensor electrode, a preparation method therefor and the use thereof are provided for the rapid and sensitive detection of glucose. The method involves: (1) performing an alkali heat treatment to form a nanoneedle-structured titanium dioxide on the surface of a titanium electrode; (2) forming micro-region grooves on a nanoneedle-structured titanium dioxide film layer to obtain a nanoneedle-structured titanium dioxide having a micropattern; (3) depositing a chlorine-doped polypyrrole in the grooves by using chronopotentiometry; (4) forming a nanocone-structured citric-acid-doped polypyrrole on the chlorine-doped polypyrrole by using chronopotentiometry; and (5) grafting an enzyme capable of detecting glucose to obtain the glucose sensor electrode. This simple and stable process is low in cost, efficiently grafts the enzyme capable of detecting glucose on the surface of the electrode, and provides a stable electrode with higher reliability for detecting glucose.

    Abstract: Provided are a display panel and a display device. The display panel includes at least two display units. Each display unit includes a substrate, a flexible substrate, a light-emitting unit circuit layer and at least one driver chip. The rigid substrate includes a display bearing region and a splicing region located on at least one side of the display bearing region. The flexible substrate is located on a first surface of the rigid substrate and located in the display bearing region, and the flexible substrate at least partially extends out of the display bearing region of the rigid substrate. The light-emitting unit circuit layer is located on a surface of one side of the flexible substrate away from the rigid substrate and includes at least one bonding pad.
