摘要： The present invention relates to an optical film having improved optical performance and to a backlight unit comprising the same. More particularly, the present invention relates to a microlens array (MLA) sheet which comprises a base unit and a lens unit formed on one side of the base unit, wherein the lens unit consists of a plurality of conical lenses. Existing hemispherical microlens array sheets have limitations in terms of improving luminance, and therefore cannot replace prism sheets in high luminance product s. However, the microlens array sheet consisting of conical lenses of the present invention can improve both luminance and viewing angle characteristics.

摘要： There is provided an optical film for backlight units or illuminators. The optical film comprises a light-incident portion and a light exit portion. Here, the optical film is characterized in that it comprises a plurality of protrusions formed on at least one of the light-incident portion and the light exit portion, wherein a plurality of the protrusions satisfies the requirements of the following Equation: 80×H1/3≦P≦200×H1/3 and 0.I×D≦H≦D, provided that a mean diameter of protrusions is represented by ‘D’, a mean height of protrusions is represented by 1H′, and a mean distance between adjacent protrusions is represented by ‘P’. Therefore, the optical film may be useful to suppress blocking between films and the formation of surface defects, which are caused by the Moire, Newton ring and wet-out phenomena, without degrading the brightness.

摘要： We describe a voltage level coding system and method. The voltage level coding system includes a level encoder having an input to receive data segments coded using a first code and an output to supply second data codes indicating one of 2N plus at least one additional voltage level to which each data segment is assigned. A converter converts the second data codes into such voltage levels. A controller output supplies the voltage levels. A method for coding digital data includes determining a first data transition, generating a code that includes at least one additional level that minimizes data skew in the first data transition, and coding the first data transition with the additional level in the code.

摘要： A data driving circuit includes a driver in which a driving current is controlled in response to predetermined bits of digital control signal and which receives a differential input data signal to generate differential output data signal; and a digital control signal generator for storing and generating the digital control signal. The driver includes a pre-driver for passing a pre driving current in response to a bias voltage and for receiving the differential input data signal(s) to generate first and second signals; and a main driver in which a main driving current is controlled in response to the digital control signal and which generates the differential output data signals in response to the first and second signals. The data driving circuit can not only vary an amplitude and a level but also shift a level, and by varying a current of the current sources in response to the digital control signal, a margin is secured in a saturation region of transistors which constitute the current sources, thereby generating a stable differential output data signals insensitive to a noise.
