Various embodiments relate to plastic-metal junctions and methods of making the same via laser-assisted joining. The present invention provides a method of forming a junction between a metal form and a solid plastic. The method can include laser treating a surface of a metal form to generate a feature (e.g., a plurality of at least one of pores and grooves) in the surface of the metal, wherein the laser has an angle of incidence with the surface of the metal of other than 0 degrees. The method can include contacting the metal surface including the feature with a flowable resin composition. The method can include curing the flowable resin composition to form the solid plastic, to provide the junction between the metal form and the solid plastic.

A display and degradation sensing method, includes a display panel having a plurality of pixels that each comprise an Organic Light Emitting Diode (OLED) and Thin Film Transistor (TFT). The pixels are divided into multiple pixel groups of two or more pixels, each connected to different data lines but to the same gate and sensing lines. A gate driving circuit supplies a scan control signal to the gate line. A data driving circuit selectively supplies turn-on driving data voltage and turn-off data voltage to the data lines in sync with the scan control signal; a sensing circuit outputs (i) a first sensing value based upon an OLED threshold voltage of a sensing pixel, and (ii) a second sensing value based upon a kickback current. A sensing value correction circuit determines a final sensing value for the OLED threshold voltage based on the first sensing value and the second sensing value.
