Provided are a display panel and an electronic terminal, including pixel units arranged along row and column directions. The pixel unit includes sub-pixels of different colors arranged along the row direction. In a first mode, two adjacent groups of pixel units are simultaneously turned on, and the sub-pixels of a same color in two adjacent columns of pixel units display a same gray scale. In a second mode, a plurality of rows of pixel units are turned on sequentially, and each sub-pixel in a plurality of columns of pixel units displays a corresponding gray scale. The refresh rate of the first mode is greater than that of the second mode, and the resolution of the first mode is smaller than that of the second mode. This shortens the time required for all rows of pixel units to be turned on, thereby increasing the refresh rate.

A wavelength selective switch (WSS) with hitless switching. The WSS includes the fiber collimator array, the focusing lens, collimating lens, diffraction grating, focusing lens, and attenuation reflection unit array. Each attenuation reflection unit has an interconnected transmission-type MEMS attenuator and a one-dimension MEMS reflector. The transmission-type MEMS attenuator is positioned in the front of the one-dimension MEMS reflector. The central axis of the transmission-type MEMS attenuator aligns and coincides with that of the one-dimension MEMS reflector, with the two central axes being glued together. The WSS of the present invention effectively utilizes the combination of a one-dimension reflector array and a transmission-type optical attenuator chip. With the use of one-dimension reflector array, instead of the known two-dimension reflector array, the complexity of design and manufacture is greatly reduced, thereby reducing the production costs of the switch.
