Vth is also a function of the viewing angle and decreases with an increase in the viewing angle from the normal of the LCD. The sharpness parameter is a measure of the steepness of the electro-optic response and gives an idea of the number of lines that can be multiplexed by using the liquid crystal mixture. A value close to 1 is preferred for ???? to be useful in an LCD with a large matrix size. Both Vth and ???? depend mainly on the NLC mixture used in the display. 6 Electro-optic response of the LCD.
Such a reduction is useful in reducing the cost of display drivers as well as interconnections and in increasing the reliability of the display. Matrix addressing is a natural choice when the number of pixels in the display is large. Matrix addressing can either use the intrinsic nonlinear character of the display as in passive matrix addressing or use an active device at each pixel as in active matrix addressing. Intrinsic nonlinearity of the device is adequate in the case of an array of LEDs and plasma display panels (PDPs).
This pre-tilt prevents a nonuniform appearance of the display arising from the reverse tilt of the molecules in the ON state. A nonsplay configuration with a twist sense matching the tilt direction is necessary to avoid the nonuniform appearance of the TN-LCD due to reverse twist patches in the unexcited state. The axis of symmetry of viewing angle characteristics of TN-LCD is at 45◦ to the director at the surface of the cell. The director direction in most TN-LCDs is at 45◦ to the edges of the display.
