  • Patent number: 6466295
    Abstract: A method of forming a LCD device having spacers is described. A mixed material is then formed on a first substrate facing a second substrate by mixing a pre-spacer material and a protrusion material with a predetermined ratio. An exposure step and a development step are performed on the mixed material to pattern the mixed material to form protrusion-spacer structures. The protrusion-spacer structures having the same height. Each protrusion-spacer structure has both a protrusion and a spacer, wherein the protrusion is formed on the first substrate, and the spacer is formed only on the protrusion, one-to-one. The first substrate and the second substrate are sealed together, wherein the gap thickness between the first substrate and the second substrate is the same as the height of the protrusion-spacer structures.

  • Patent number: 6433766
    Abstract: A data transmission method for reducing the electromagnetic interference intensity of a liquid crystal display circuit comprises a pixel array, a clock signal generator for providing a plurality of clock signals, a data generator for providing a plurality of data sets, and a plurality of drivers. Each of the drivers receives a corresponding data set from the data generator and a clock signal from the clock signal generator, and transmits the corresponding data to the pixel array. The data transmission method is characterized in that the clock signal generator generates a plurality of clock signals with different frequencies. Each of the plurality of different frequencies is distributed around a central frequency and varied within a bandwidth of 5% of the central frequency. The clock signals have different frequencies at a given time, and the clock signals used by two adjacent drivers have different frequencies.

  • Patent number: 6414675
    Abstract: A personal computer (PC) system has, amongst other circuitry and devices, a CD drive, a CD playing control circuit, an embedded controller, a CD control panel and an embedded display program contained within the Basic Input Output System (BIOS) of the memory of the computer. With the CD drive, the CD playing control circuit and the CD control panel, a user can listen to a CD when the computing and display portions of the PC system are turned off. However, upon a predetermined button pressing of the CD control panel, the embedded controller will turn on both the processor and the display of the PC system, and cause the processor to begin executing the embedded display program.
