Abstract
An information handling system peripheral display couples a midplane to a display panel back side with punched metal geometric structures that slide into midplane slots. A timing controller board of the display panel has an edge connector that interfaces with a scalar board edge connector when the scalar board couples with slots at posts of the back side. The scalar board couples display cable ports to accept display information from an information handling system and extends the display cable ports out of openings of the midplane. A modular scalar board couples to the display to enhance display functionality. EDID information is stored on display component boards and retrieved to a scalar board to operate the display.
Claims16
An information handling system comprising:
- a housing;
- a processor coupled in the housing and operable to execute instructions that process information;
- a memory coupled in the housing and interfaced with the processor, the memory operable to store the instructions and information;
- a peripheral display external the housing and interfaced with the processor to present the information as visual images, the peripheral display having a display panel with an array of pixels to present the visual image, a timing controller board having a timing controller interfaced with the array of pixels to scan visual image values to the pixels, and a scalar board interfaced with the timing controller board, the scalar board having a first scalar interfaced with the timing controller and configured to control display panel visual image presentation;
- a first non-transitory memory coupled to the scalar board and interfaced with the first scalar to store a first set of extended display identification data (EDID);
- a second non-transitory memory coupled to the timing controller board and interfaced with the timing controller to store a second set of EDID;
- a modular input/output board separate from the peripheral display and having a connector to interface with a port of the scalar board;
- a third non-transitory memory coupled to the modular input/output board to store a third set of EDID.
A method for presenting visual images at a peripheral display, the method comprising:
- storing first EDID in a first non-transitory memory of a timing controller board;
- storing second EDID in a second non-transitory memory of a scalar board;
- communicating the first EDID to the scalar board;
- applying the first and second EDID by a scalar to present visual images at a display panel;
- storing a third EDID in a third non-transitory memory of a power board;
- communicating the third EDID to the scalar board;
- and
- applying the third EDID to manage power at the peripheral display with the scalar.
A peripheral display comprising:
- a housing;
- a display panel coupled in the housing and having an array of pixels to present information as visual images;
- a timing controller board coupled in the housing and having a timing controller interfaced with the array of pixels to scan visual image values to the pixels;
- a scalar board coupled in the housing and interfaced with the timing controller board, the scalar board having a first scalar interfaced with the timing controller and configured to control display panel visual image presentation;
- and
- a first non-transitory memory coupled to the scalar board and interfaced with the first scalar to store a first set of extended display identification data (EDID), the first non-transitory memory storing EDID associated with the first scalar;
- a second non-transitory memory coupled to the timing controller board and interfaced with the timing controller to store a second set of EDID, the second non-transitory memory storing EDID associated with the display panel, the first scalar retrieving the EDID from the second non-transitory memory to apply to present visual images at the display panel;
- a power board coupled in the peripheral display and interfaced with the scalar board to provide power to the scalar board;
- and
- a third non-transitory memory coupled to the power board to store a third set of EDID associated with the power board and retrieved by the first scalar to manage power.
