In a display panel, pixels each including a plurality of sub-pixels are arranged in a matrix form, wherein each of the plurality of sub-pixels includes: an inorganic light-emitting element; a constant current generator circuit that provides a driving current to the inorganic light-emitting element on the basis of a constant current generator data voltage; and a PWM circuit for controlling the time for the driving current to flow through the inorganic light-emitting element on the basis of a PWM data voltage, wherein the constant current generator circuit includes a first driving transistor and the PWM circuit includes a second driving transistor, and wherein the constant current generator circuit or the PWM circuit comprises an internal compensation circuit that compensates for electrical characteristics of the first driving transistor and the second driving transistor.

Provided are a display panel and a display device. The display panel includes a pixel driver circuit. The pixel driver circuit includes a light-emitting module, a drive transistor and at least one light-emitting control transistor. The drive transistor, the light-emitting control transistor and the light-emitting module are connected in series between a first power supply signal terminal and a second power supply signal terminal, and at least one of the drive transistor or the light-emitting control transistor is a first double-gate transistor. The first double-gate transistor includes a first gate, a second gate and a first source, and the second gate is electrically connected to the first source.

A current-selectable light-emitting-diode (LED) display includes pixels distributed in an array of rows and columns. The pixels are grouped in mutually exclusive clusters and cluster controllers are connected to each pixel in a cluster of pixels to control the pixels in the cluster to emit light. Each cluster controller comprises a selectable current source. Each of the selectable current sources can include cluster current sources that are responsive to a current-select signal to enable one or more of the cluster current sources. The pixels can include micro-LEDs and the cluster controller can be disposed between the micro-LEDs. The display can be disposed on a display substrate with signal wires. The signal wires can include separate wire segments that are electrically connected through regeneration circuits that regenerate the signals. The display can be an information display or a backlight.
