Micro display driving substrate for head-mounted display

A micro display driving substrate for a head-mounted display (HMD) terminal unit worn by a user, the micro display driving substrate comprising:

• an LCoS (Liquid Crystal on Silicon) pixel array configured of one or more first electrode lines arranged while keeping a predetermined distance and one or more second electrode lines arranged to intersect with the first electrode lines while keeping a predetermined distance;
• a data driving unit for supplying the video data converted into an analog signal to the first electrode lines of the LCoS pixel array;
• a line driving unit for receiving the video control signal and providing a line selection signal for selecting a second electrode line so that the video data stored on the first electrode lines for a predetermined time period may be transferred to and stored in a pixel of a relevant line;
• and
• a support control unit for driving a light source needed to display an image, while controlling an on/off time and brightness of the light source,
• wherein the LCoS pixel array, the data driving unit, the line driving unit and the support control unit to be embedded in the micro display driving substrate.
