    • Microfluidic pixels (110) are utilized to produce large format displays (billboards) (100) that are both digitally controllable and are light weight. Each microfluidic pixel (110) includes a wall having a front (display) surface, and a microfluidic system including a reservoir disposed behind the wall, a colorant fluid, a transparent display chamber disposed in front of the wall, a conduit, and a two-way pump. In the absence of colorant fluid in display chamber, the pixel (110) has a background appearance determined by the color (e.g., white) of the front wall surface. The pump receives a digital control signal from a digital control circuit to transfer colorant fluid from the reservoir to the display chamber by way of the conduit, whereby the pixel's appearance changes to a "colored" appearance determined by the color and amount of the colorant fluid in the display chamber.
    • 微流体像素(110)用于产生数字可控且重量轻的大格式显示器(广告牌)(100)。 每个微流体像素(110)包括具有前(显示器)表面的壁和包括设置在壁后面的储存器的微流体系统,着色剂流体,设置在壁前面的透明显示室,导管和两个 路泵。 在显示室中没有着色剂流体的情况下,像素(110)具有由前壁表面的颜色(例如白色)确定的背景外观。 泵从数字控制电路接收数字控制信号,以通过导管将着色剂流体从储存器转移到显示室,由此像素的外观变为由着色剂流体的颜色和数量确定的“有色”外观 在显示室。
