    • A video display device is described, which is capable of easily correcting variations in luminous brightness of each display element. When a video display part is comprised of a plurality of display units including a plurality of display elements, respective correction data for correcting the variations in luminous brightness of the individual display elements are supplied to memory means. When the display elements are driven, the correction data is supplied to their corresponding drivers. In doing so, the display elements can be driven in a corrected state of the variations in luminous brightness. Even when a unit cell comprising display elements is replaced by another and brightness level is re-adjusted, new correction data relative to it is updated. Said updated correction data may simply be stored in the same memory means. Thus, the variations in luminous brightness can be easily corrected even when the unit cell is replaced by another and re-adjusted.
    • 描述了一种视频显示装置,其能够容易地校正每个显示元件的发光亮度的变化。 当视频显示部分由包括多个显示元件的多个显示单元组成时,用于校正各个显示元件的发光亮度变化的相应校正数据被提供给存储装置。 当显示元件被驱动时,校正数据被提供给它们相应的驱动器。 在这样做时,显示元件可以在发光亮度变化的校正状态下被驱动。 即使当将包括显示元件的单位单元替换为另一个单元,并且重新调整亮度水平时,相对于其更新的新的校正数据被更新。 所述更新的校正数据可以简单地存储在相同的存储器装置中。 因此,即使当单元更换为另一个并重新调整时,也可以容易地校正发光亮度的变化。

    • A video display device is capable of performing a high-speed switching process and preventing video flicker from occurring. The video display device comprises a plurality of display units including a plurality of unit cells. The unit cell comprises a plurality of dots arranged vertically and horizontally each other and divided into a plurality of dot groups. Each dot is comprised of a plurality of display elements. Further, each unit cell is provided with a plurality of memories, a driving means and a switching means. The memories store the video data to be supplied to display elements. The driving means reads the video data corresponding to said dot groups stored in one of the memory and drives the display elements of said dot groups based on the read video data. The switching means switches alternately and successively the dot groups. The memories store the video data successively in a one-frame unit or a one-field unit. Since video signal written to the memory in a one-frame unit or one-field unit is read therefrom in the one-frame unit or the one-field unit, the dot groups may be switched at highs speed. Thereby, the video flicker maybe prevented from occurring.
    • 视频显示装置能够执行高速切换处理并防止视频闪烁发生。 视频显示装置包括多个显示单元,包括多个单位单元。 单元单元包括垂直和水平相互排列并分成多个点组的多个点。 每个点由多个显示元件组成。 此外,每个单元单元设置有多个存储器,驱动装置和开关装置。 存储器存储要提供给显示元件的视频数据。 驱动装置读取对应于存储在其中一个存储器中的所述点组的视频数据,并且基于读取的视频数据驱动所述点组的显示元素。 切换装置交替地并且连续地切换点组。 存储器以一帧单位或一场单位连续地存储视频数据。 由于在一帧单位或单场单位中从其中读取以一帧单位或单场单位写入存储器的视频信号,所以可以以高速切换点组。 因此,可以防止视频闪烁发生。

    • Light emission data is supplied to an RDATA latch 13R, a GDATA latch 13G, and a BDATA latch 13B and latched as R, G, and B data for every pixel. In an arithmetic operation processing unit 14, an arithmetic operation is performed using the latched R, G, and B data and a chromaticity correction coefficient Cij written in a chromaticity correction coefficient register 16. An arithmetic operation result of the arithmetic operation processing unit 14 is supplied as correction light emission data into a data memory 15 and stored. In a luminance correction data memory 20, luminance correction data is supplied to a constant current driver 18 in accordance with a supplied control signal. The constant current driver 18 drives an LED display 19 in accordance with the correction light emission data and the luminance correction data.
