A pixel of a display apparatus includes at least a first transistor and at least a125 second transistor. A cell of transparent fluid including particles charged to have different polarities from each other is arranged between a pixel electrode and a common electrode. The first and second transistors are connected to the pixel electrode. The pixel is drivable according to pulse amplitude modulation (PAM) and pulse width modulation (PWM) such that a frame of an image is displayable using a single field.

Provided are methods and apparatuses for encoding data. One method of encoding data includes generating second data by altering locations of bits within first data to be encoded next based on values of bits within at least one piece of previously encoded data; and entropy-encoding the second data. Also provided are methods and apparatuses for decoding data.
摘要:
A method and apparatus for encoding and decoding an image. The encoding method includes: deciding whether pixel values of a first block of an image are identical to pixel values of a second block of the image that is encoded prior to the first block in a current slice of the image, and determining whether to encode the first block in a first mode according to the deciding; and selectively encoding the first block in the first mode based on the determining, wherein the first mode is a mode for encoding information representing that the first block is encoded in the first mode, instead of encoding the pixel values of the first block, when the first block is identical or similar to the second block.

According to example embodiments, an electrochromic device includes pixel containing a first sub-pixel and a second sub-pixel. The first sub-pixel includes a first electrolyte contacting a first electrochromic layer. The first electrochromic layer includes a first electrochromic material configured to display each one of transparency and at least two colors, based on a voltage applied to the first electrochromic material. The second sub-pixel includes a second electrolyte contacting a second electrochromic layer. The second electrochromic layer includes a second electrochromic material configured to display each one of transparency, black, and at least one color other than black, based on a voltage applied to the second electrochromic material.
摘要:
A flat panel display device including a display area where an image is displayed and a non-display area located at an outside of the display area includes bank portions arranged in a pattern in the display area and partitioning a plurality of openings, emission elements located in the openings, dummy bank portions formed in the non-display area and integrated therewith, and a sealing passivation layer having a multi-layered structure of organic films and inorganic films alternately arranged, one organic film being located at an interface directly contacting the emission element and one inorganic film located firstly on an outermost portion of the dummy bank portions when the sealing passivation layer extends from the display area to the non-display area.
摘要:
A polymerized toner is provided. The polymerized toner comprises a reactive anionic surfactant having at least one reactive functional group. The reactive anionic surfactant is added simultaneously with a dispersant to prepare an aqueous dispersion or is added within 2 hour after a polymerization reaction of a monomer mixture is initiated in an aqueous dispersion. This simultaneous or rapid addition allows the reactive anionic surfactant to be dispersed on the surface of the toner particles. The reactive anionic surfactant is located over the entire surface of the toner particles to increase the surface charge density of the toner, achieving good charge stability and excellent imaging characteristics.
