Abstract: A fringe field switching liquid crystal display (FFS-LCD) device (200) includes a first substrate (210) and a second substrate (220) disposed opposite to each other and spaced apart a predetermined distance, a liquid crystal layer (250) interposed between the first and second substrates, a plurality of gate lines (233) and data lines (234) formed on the second substrates, thereby defining a plurality of pixel regions, and a plurality of pixel electrodes (223) and a plate-like common electrode (221) provided in each of the pixel regions. The pixel electrodes have a plurality of curving comb portions so as to generate a continuous variation electric field between the pixel and common electrodes. Liquid crystal molecules in the FFS-LCD device are twisted in different continuous directions so as to reduce the color shift.

Abstract: A reflective type IPS LCD includes a transparent upper substrate (100) and a lower substrate (200), and liquid crystal molecules (300) interposed between the substrates. A reflection layer (250) is disposed on the lower substrate. A plurality of gate lines (170) and a plurality of data lines (180) are formed on the upper substrate, thereby defining a plurality of pixel regions arranged in a matrix. Each pixel region includes pixel electrodes (210) and common electrodes (220). The pixel electrodes and the common electrodes have a bent configuration, and are spaced apart from each other. Therefore the electric field generated by them is along two directions, and the LCD exhibits a two-domain display effect. When viewing the LCD display from any oblique angle, the color shifts generated by the two domains counteract, and thus the overall color shift of the display is small.

Abstract: An in plane switching liquid crystal display (2) includes a first substrate (27), a second substrate (37) and a liquid crystal layer (23) having a plurality of liquid crystal molecules. A number of pixel electrodes (25) and common electrodes (24) are formed on the first substrate, and each of the pixel electrodes and common electrodes include at least two bend portions (241, 242, 243). Each bend portion has a first side and a second side. An original alignment direction of the liquid crystal molecules form at least two different angles with the sides of the bend portions of the common and pixel electrodes. When a voltage is applied to the pixel electrodes and the common electrodes, the liquid crystal molecules are aligned along at least three different directions. Therefore, the IPS-LCD can have uniform viewing performance at different viewing angles.

Abstract: An IPS mode LCD (100) includes a first substrate (111), a second substrate (114), a layer of liquid crystal molecules (116) held therebetween, a plurality of gate lines (130) arranged on the second substrate, an insulative layer (120) formed on surfaces of the second substrate and the gate lines, a plurality of data lines (117) arranged on the insulative layer, a passivation layer (118) formed on surfaces of the insulative layer and the data lines, and a plurality of pixel electrodes (127) and common electrodes (115) arranged on the passivation layer. The common electrodes partly overlap corresponding data lines. Back light transmitting from the second substrate toward the first substrate is blocked by the data lines and only parts of the common electrodes. Thus an aperture ratio of the IPS mode LCD is raised, and a brightness and display quality of the IPS mode LCD is enhanced.

Abstract: A liquid crystal display device (100) includes an upper substrate (12), a lower substrate (11), and a liquid crystal layer (130) between the upper substrate and the lower substrate. The upper substrate includes an upper polarizer (143) and a color filter layer (127), the upper polarizer being an extraordinary type polarizer. The lower substrate includes a reflective film (119). A multiplicity of pixel electrodes (113) and common electrodes (111) are positioned at the lower substrate, for applying a voltage to the liquid crystal layer. The display device has a wide viewing angle, can work at high temperatures, and is relatively thin and compact. Further, the color filter layer is positioned above the upper polarizer. Optical beams reach the color filter layer after passing back through the liquid crystal layer and the upper polarizer. This reduces or eliminates color filter de-polarizing, and yields a high contrast ratio over wide viewing angles.

Abstract: A transflective mode liquid crystal display (2) includes a first substrate (211) and a second substrate (210), a liquid crystal layer (230) interposed between the first substrate and the second substrate, a plurality of pixel electrodes (213) and a plurality of counter electrodes (212) formed on the first substrate, a color filter (250) disposed on an inner surface of the second substrate, and a transflective element (271) disposed on the first substrate. The color filter has a color resin layer, which comprises a transmission section and a reflection section. Brightness and color saturation of light beams emitted from the transmission section are substantially the same as those of light beams emitted from the reflection section. Therefore, the transflective mode liquid crystal display has improved color and brightness characteristics.

Abstract: An in plane switching liquid crystal display (2) includes a first substrate (220) and a second substrate (210) disposed opposite each other and spaced apart a predetermined distance. A liquid crystal layer is interposed between the first substrate and the second substrate, the liquid crystal layer containing a plurality of liquid crystal molecules (230). A plurality of pixel electrodes (213) and a plurality of counter electrodes (211) are formed on the first substrate in parallel alternating fashion. Two polarizers (240, 241) are disposed on the first substrate and the second substrate, respectively. A transflector (217) capable of transmitting and reflecting light beams is disposed on the first substrate. The in plane switching liquid crystal display can thus utilize ambient light beams as well as light beams provided by a backlight, so that the in plane switching liquid crystal display has low power consumption.

Abstract: An LCD device (2) includes two substrates (21, 22), a liquid crystal layer (27) therebetween, and gate lines (24) and data lines (23) formed on one of the substrates thereby defining pixel regions. A set of pixel electrodes (26) and a set of common electrodes (25) are provided in each pixel region. The pixel and common electrodes are shaped as hollow rectangles, and are alternately nested one within the other. When a voltage is applied, a horizontal electric field in two different directions (281, 282) is established. Liquid crystal molecules of the liquid crystal layer are twisted according to the two directions, thereby reducing color shift.

Abstract: A liquid crystal display (2) has a first substrate (21), a second substrate (22), and liquid crystal molecules (26) interposed between the substrates. Curved first slits (211) and curved second slits (221) are defined at insides of the substrates respectively. When an electric field is applied between the substrates, the liquid crystal molecules are inclined to be oriented parallel to the substrates. In addition, the curved first slits and the curved second slits affect the orientations of the liquid crystal molecules, such that the liquid crystal molecules are directed to incline in various directions in smooth continuums. The visual effect of the continuous domain vertical alignment liquid crystal display is the sum of multiple smooth continuous domains. Thus the continuous domain vertical alignment liquid crystal display provides a more even display performance at various different viewing angles.

Abstract: A multi-domain IPS (in-plane switching) liquid crystal display (20) includes a first substrate (201), a second substrate (202), liquid crystal molecules (203) filled between the first and second substrates, and gate lines (211) and data lines (212) formed on the first substrate. The gate lines and data lines define pixel regions arranged in a matrix. Each pixel region includes pixel electrodes (233), common electrodes (243), and a TFT (thin film transistor) (220). The pixel electrodes and the common electrodes have a same curved shape, and are uniformly spaced apart from each other. Therefore the electric field generated by them is a smooth continuum of multiple domains, and the visual performance at various different viewing angles is equally good. Because the pixel and common electrodes do not have sharp bends, disclination is avoided. Therefore the IPS liquid crystal display has a high contrast ratio.

A plurality of curved first protrusions (211) and a plurality of curved second protrusions (221) are disposed at insides of the substrates respectively. When an electric field is applied between the substrates, the liquid crystal molecules tend to be oriented parallel to the substrates. In addition, the curved protrusions affect the orientations of the liquid crystal molecules, such that the liquid crystal molecules are directed to incline in various directions in smooth continuums. The visual effect of the continuous domain vertical alignment liquid crystal display is the sum of multiple smooth continuous domains. Thus the continuous domain vertical alignment liquid crystal display provides a more even display performance at various different viewing angles.

A time period of the voltage applied on the pixel electrode is changeable according to the gray level needed by the image, and so display different grays are obtained through controlling the time that the voltages is applied to the LCD device.
