    Abstract: An in-cell touch panel and a display device, a touch driving method are disclosed. A common electrode layer in an array substrate is partitioned into a plurality of sub-electrodes arranged in an array. Sub-electrodes that are alternately disposed in a respective row of sub-electrodes serve as touch driving sub-electrodes that form a touch driving electrode. Sub-electrodes other than the touch driving sub-electrodes serve as common sub-electrodes. Touch sensing electrodes with projections within areas where corresponding common sub-electrodes are located are provided on an opposed substrate. Upon a line-by-line scanning of gate lines covered by respective rows of sub-electrodes, sub-electrodes in a currently-scanned row are applied with a common electrode signal, touch driving electrodes in rows of sub-electrodes other than the currently-scanned row of sub-electrodes are applied with touch driving signals.

    Abstract: The present application discloses a display apparatus including an image display portion for displaying an image, the image display portion emitting display light along a light propagating direction; and a light modulator assembly having a first light modulator and a second light modulator arranged in series along the light propagating direction. The second light modulator has at least a reflective optical state. The first light modulator is switchable between the reflective optical state and a transmissive optical state and is on a side of the second light modulator proximal to the image display portion. A total number of light modulators including the second light modulator and any light modulator on a side of the second light modulator proximal to the image display portion is N, N is an integer≥2.
