연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Technologies are generally described for an adjustable display screen such as for a notebook computer or other portable device. In some examples, at least one display screen rail may be rotatably coupled to a back edge of a notebook computer base unit at a hinge rod. The display screen of the notebook computer may slide along and/or pivot on the at least one display screen rail in a direction to bring the display screen toward a user of the notebook computer while leaving room for the user to access a keyboard located on a top surface of the base unit. Mechanisms may be coupled to the notebook computer to transmit motion of the display screen along a first display screen rail to motion of the display screen along a second display screen rail, thereby mitigating binding of the display screen as it slides along the display screen rails.

The apparatus of claim 1 wherein the first and second belts comprise toothed belts. 3. The apparatus of claim 2 wherein the first and second toothed belts are located at least partially within a respective one of the first and second display screen rails. 4. The apparatus of claim 1 wherein the display screen housing is adapted to slide along and pivot on the first and second display screen rails in a direction that facilitates user access to a user input device located on a top surface of the base unit. 5. The apparatus of claim 1 further comprising a display screen cable coupled between the display screen housing and the base unit through at least a portion of the hinge rod, wherein the display screen cable is substantially hidden behind the display screen housing when the display screen housing is moved to a substantially downward position relative to the base unit along the first and second display screen rails. 6. The apparatus of claim 5 wherein the display screen cable is adapted to unfold from behind the display screen housing when the display screen housing is moved to a substantially upward position relative to the base unit along the first and second display screen rails. 7. The apparatus of claim 6 wherein the display screen cable is a ribbon-type cable. 8. The apparatus of claim 1 further comprising a display screen coil cable coupled between the base unit and the display screen housing through a slot in either the first or second display screen rail, wherein the display screen coil cable is adapted to expand within said first or second display screen rail when the display screen housing is moved upward relative to the base unit along the first and second display screen rails, and wherein the display screen coil cable is adapted to contract within either the first or second display screen rail when the display screen housing is moved downward relative to the base unit along the first and second display screen rails. 9. The apparatus of claim 1 further comprising a scissor joint mechanism coupled between a bottom portion of the display screen housing and the back edge of the base unit, wherein the scissor joint mechanism is adapted to open or contract as the display screen housing is moved up or down, respectively, along the first and second display screen rails. 10. The apparatus of claim 9 wherein the scissor joint mechanism comprises: a slidable first horizontal scissor joint rail coupled to the bottom of the display screen housing and slidably coupled to the first and second display screen rails at each end of the slidable first horizontal scissor joint rail;a fixed second horizontal scissor joint rail positioned below the first horizontal scissor joint rail; anda set of scissor joint arms having ends slidably coupled to the first and second scissor joint rails such that sliding of the display screen housing downward along the first and second display screen rails causes the set of scissor joint arms to collapse such that the distance between the slidable first horizontal scissor joint rail and fixed second horizontal scissor joint rail decreases when the set of scissor joint arms are in a substantially collapsed position. 11. The apparatus of claim 1 wherein the first and second display screen rails have dimensions such that when the apparatus is in a closed position, exterior sides of the first and second display screen rails are substantially even with side walls of the base unit, and front ends of the first and second display screen rails are substantially even with a front edge of the base unit. 12.

The apparatus of claim 13, wherein the first and second belts comprise toothed belts. 15. The apparatus of claim 13 further comprising a scissor joint mechanism positioned below the display screen housing and adapted to open or contract when the position of display screen housing is slid up or down, respectively, along the first and second display screen rails. 16. An apparatus comprising: an enclosed display screen rail housing having a slot opening into the enclosed display screen rail housing, the slot located along an interior wall of the enclosed display screen rail housing such that the slot is configured to face an edge of a display screen housing;a toothed belt positioned within the enclosed display screen rail housing, the toothed belt running substantially the length of the enclosed display screen rail housing;a first gear located within the display screen rail housing at a first end of the enclosed display screen rail housing and adapted to mesh with the toothed belt;a hinge rod that extends out of the enclosed display screen rail housing, wherein the first gear is coaxially coupled to the hinge rod, and wherein the enclosed display screen rail housing is rotatable about the axis of the hinge rod and first gear;a second gear located within the display screen rail housing at an opposite end of the enclosed display screen rail housing, wherein the second gear is adapted to mesh with the toothed belt so that the toothed belt, first gear, and second gear are adapted to rotate in unison;a carriage coupled at a fixed location on the toothed belt such that when the toothed belt rotates, the carriage moves with the toothed belt up and down the inside of the enclosed display screen rail; anda hinge pin coupled to the carriage, the hinge pin extending through the slot for attachment to the edge of the display screen housing facing the enclosed display screen rail housing, wherein the hinge pin is arranged to allow the display screen housing to pivot with respect to the enclosed display screen rail housing, wherein the display screen rail housing, the toothed belt, the carriage and the hinge pin are arranged in cooperation with one another such that when the hinge rod rotates, the first and second gears and the toothed belt also rotate, causing the carriage and the hinge pin coupled thereto to move with the toothed belt up and down the inside of the enclosed display screen rail housing to effect sliding the hinge pin and display screen housing along the slot in the enclosed display screen rail housing while the display screen housing remains free to pivot about the hinge pin. 17. The apparatus of claim 16 further comprising a display screen coil cable coupled to the display screen housing through the slot in the display screen rail housing and adapted such that the coil expands within the display screen rail housing when the display screen housing is slid in one direction along the slot and contracts within the display screen rail housing when the display screen housing is slid in an opposite direction along the slot.
