Abstract: A method for driving a pixel array, a device, and a display panel are provided. The data lines electrically connected to the sub-pixels are electrically connected with data signal terminals through switch modules, respectively. The switch modules receive selection control signals to switch connection states of the data lines with the data signal terminals. The method includes: applying gate signals to a gate line corresponding to the first row of sub-pixels and a gate line corresponding to the second row of sub-pixels, respectively; and during a period of applying the gate signals to the second row of sub-pixels to control the second row of sub-pixels, after a first duration length of the gate signals applied to the first row of sub-pixels being switched from the on-state to the off-state, a selection control signal corresponding to the second row of sub-pixels controlling the switch modules to switch the connection states.

Abstract: The present disclosure provides a mobile phone waterproof bag sealing assembly, including a bag body used to accommodate a mobile phone. The sealing assembly includes: a flip fixture and a fixing part. The flip fixture includes a first clamp plate and a second clamp plate which are integrated; the bag body is spread along an edge of the first clamp plate; a side surface of the bag body is adhered to an inner wall surface of the first clamp plate and/or the second clamp plate; an opening of the bag body is folded by means of flipping the first clamp plate and the second clamp plate, and a sealing fold is formed on the bag body. The bag body is driven to be folded by means of flipping the first clamp plate and the second clamp plate, and then the flip fixture is kept in the closed state.

Abstract: Methods and apparatuses for headbands and head-worn devices are described. In one example, a headband includes a lace. The headband includes a tightenable apparatus disposed along a length of an inner side of the headband, the tightenable apparatus coupled to the lace and arranged to tighten or relax responsive to control of the lace. The headband further includes a cushion arranged to contact a wearer head.
