Abstract
A display panel capable of capturing an image of an object over a light-entering surface thereof includes a displaying array, a light valve array, and an imaging array, which are sequentially below the light-entering surface. The light valve array includes a plurality of light valve portions and can form a plurality of first mask patterns, and at least two first mask patterns are configured to be different. The displaying array includes a plurality of displaying pixels and can form a second mask pattern. The imaging array includes a plurality of imaging pixels and can generate an intermediate image upon receiving lights from the object and transmitting through the second mask pattern in the displaying array and at least one of the plurality of first mask patterns in the light valve array. The image of the object can then be deduced from the intermediate image.
