Abstract: A display substrate (20) and a display device (40). The display substrate (20) comprises a base substrate and a plurality of sub-pixels (100) located on the base substrate. Each sub-pixel (100) comprises a pixel circuit and a pixel electrode (134) electrically connected to the pixel circuit, and each pixel circuit comprises a driving sub-circuit. The pixel electrodes (134) each comprises an electrode body part (140) and a first electrode extension part (142) extending from the electrode body part (140). The display substrate (20) comprises first-type sub-pixels. The electrode body part (140) of each first-type sub-pixel (100) does not overlap a control electrode of the driving sub-circuit of the sub-pixel or an electrode part directly electrically connected to the control electrode, and the first electrode extension part (142) of each pixel electrode (134) at least partially overlaps the control electrode or the electrode part.

Abstract: The disclosure relates to 433 MHz solid state microwave heating cavity and industrial defrosting system. The 433 MHz solid state microwave heating cavity and industrial defrosting system includes a sample conveying device, a metal detector, a microwave processing system, and a motor, provided on a machine frame. An upper part and a bottom part of a microwave processing module are provided with a microwave source separately. Microwave sources are connected to bell mouths through wave guide tubes. Two bell mouths are connected to a heating cavity through microwave windows. The microwave source is a 433 MHz solid-state microwave source. The high-power-density 433 MHz microwave is used to penetrate meat products to make a uniform temperature inside and outside after defrosting, the defrosting takes only 2-4 minutes from ?18° C. to ?2° C., color and nutrients of the meat products after the defrosting are basically the same as those of fresh meat.
