Display device and electronic apparatus
According to an aspect, a display device includes an image display panel, data lines, and scan lines. The image display panel includes arrays of pixels including a plurality of sub-pixels. The arrays of pixels include cyclically arranged columns of first columns each of which includes first sub-pixels, second columns that include second sub-pixels, and third columns. Third sub-pixels and fourth sub-pixels are alternately arranged in the third columns in the direction along the third columns, and are alternately arranged in a direction along the row in the same row of the third columns. Each of the scan lines is coupled to either of the third sub-pixels adjacent thereto or the fourth sub-pixels adjacent thereto, as sub-pixels to be selected thereby.
LIQUID CRYSTAL DISPLAY APPARATUS
A liquid crystal display apparatus comprises a planar first electrode, multiple second electrodes and third electrodes that overlap with the first electrode and are alternately arranged, in correspondence to one subpixel. The second electrode and the third electrode are independently driven. A voltage for driving the liquid crystal is individually applied between the second electrode and the first electrode and between the third electrode and the first electrode.
Liquid crystal display device
Provided is a liquid crystal display device in which both a vertical electric field and a horizontal electric field are used and flickering is hardly recognized. The liquid crystal display device includes a liquid crystal panel and a control unit. The control unit includes a horizontal electric field control unit and a vertical electric field control unit. The horizontal electric field control unit controls the potentials of pairs of drive electrodes included in the liquid crystal panel, and thereby controls a horizontal electric field that is generated between each pair of drive electrodes. The vertical electric field control unit controls the potentials of a common electrode and an opposite electrode included in the liquid crystal panel, and thereby controls a vertical electric field that is generated between the common electrode and the opposite electrode. The horizontal electric field control unit controls the intensity and the polarity of the horizontal electric field when the vertical electric field control unit is causing the vertical electric field to be generated. The vertical electric field control unit inverts the polarity of the vertical electric field when the horizontal electric field control unit is maintaining the polarity of the horizontal electric field.
ELECTRONIC DEVICE
A highly convenient electronic device used while being worn on a body is provided. The electronic device is an arm-worn electronic device including a display panel, a power storage device, a circuit, and a sealing structure. The display panel displays an image with power supplied from the power storage device. The circuit includes an antenna and charges the power storage device wirelessly. Inside the sealing structure, the display panel, the power storage device, and the circuit are provided. The sealing structure includes a portion that transmits visible light. The sealing structure can be worn on an arm or is connected to a structure body that can be worn on an arm.
CHOLESTERIC LIQUID-CRYSTAL DISPLAY DEVICE AND METHOD FOR DRIVING THE SAME
A method for driving a cholesteric liquid-crystal display device is provided. The cholesteric liquid-crystal display device includes a cholesteric liquid-crystal display panel and a driving circuit section. The cholesteric liquid-crystal display panel includes a plurality of scanning electrodes and a plurality of data electrodes. The method includes the following steps: utilizing the driving circuit section to sequentially activate each of the scanning electrodes using a pulse-width modulation (PWM) scanning procedure, which comprises a selection stage and a non-selection stage; and during the selection stage of each pixel circuit on an activated scanning electrode among the plurality of scanning electrodes, utilizing the driving circuit section to add one or more first additional voltage pulses and one or more second additional voltage pulses to a negative half cycle and a positive half cycle of a common AC voltage pulse applied to each pixel circuit on the activated scanning electrode, respectively.
