The present disclosure provides a light valve, a display device and a display method. The light valve includes: at least one fixation member fixed onto a substrate; and at least one movable member capable of moving relative to the fixation member to switch the light valve between a first state where the light valve is provided with a slit through which a light beam passes and a second state where the light valve prevents the light beam from passing therethrough.

Light valve, display device and display method

A method for issuing coupons to a plurality of target users is provided. For each of the plurality of target users, the method may include determining a predicted value of a group indicator of the target user in a predetermined period. The method may further include grouping the plurality of target users using a plurality of grouping strategies. For each of the grouping strategies, the method may further include determining a candidate coupon issuing strategy. For each of the candidate coupon issuing strategies, the method may further include obtaining user feature information of one or more target users in each group corresponding to the candidate coupon issuing strategy. For each of the candidate coupon issuing strategies, the method may further include predicting an ROI of the candidate coupon issuing strategy based on an RO prediction model and the corresponding user feature information.

Systems and methods for coupon issuing

The present disclosure provides a pixel structure, a method of driving a pixel structure, an array substrate, and a display device. The pixel structure includes a fixed substrate, an electrically conductive layer at a side of the fixed substrate, a movable shield at another side of the fixed substrate, and an electrically conductive film. The fixed substrate includes a transparent substrate and a dielectric layer. The electrically conductive layer and the dielectric layer are configured to form one or more interference air gaps according to a pixel voltage applied between the electrically conductive layer and the electrically conductive film. The movable shield is configured to change an amount of incident light irradiating the electrically conductive layer.

Pixel structure, method for manufacturing pixel structure array substrate, and display device

A display panel includes an array substrate, and a plurality of display units disposed on the array substrate each of which includes a display sub-pixel for receiving sunlight radiation and performing display, a solar cell disposed adjacent to the display sub-pixel and configured to receive sunlight radiation and perform photoelectric transformation, a micro-electromechanical optical valve disposed above and movable over the display sub-pixel and the solar cell to control a light transmittance of the display sub-pixel, and a blocking structure disposed at an edge of the display unit to limit the movement of the micro-electromechanical optical valve within the display unit.
