DISPLAY DEVICE HAVING IMAGE SENSE REVERSAL CAPABILITY Abstract of the Disclosure An improved display device utilizes an electro- optical panel including an electrically insulating layer and a light-modulating layer of dipole, light control par- ticles dispersed in a transparent matrix. An imaging electric charge pattern is impressed on the panel to establish a particle orienting field thereacross. The light modulating pattern thus created in the modulating layer is selectively changed between positive and negative image sense by selective application and removal of a uniform field of the same polarity as, but lesser magnitude than, the imaging charge pattern. The stored image pattern is erasable by application of a reverse polarity field. Preconditioning the panel with a uniform field facilitates a positive light modulating pattern in the first instance.
