Calibrator for a display screen

摘要

There is disclosed a calibrator configured to calibrate a color of a screen of a display device includes an absorption plate formed of a transformable material, comprising a bottom surface attached to the screen of the display device in a vacuum absorption method; a control portion configured to leave space a first portion of the absorption plate from the screen of the display device; a fixed portion configured to press a second portion of the absorption plate to the screen of the display closely; a rotary portion configured to rotatably coupled to the fixed portion in a horizontal direction and to move the control portion in a vertical direction of the display device, when it is rotated; and a circuit unit mounted in the fixed portion to calibrate the color of the display device, such that the calibrator may be fixed in a precise position of the screen and that the screen calibration can be performed precisely and that the calibrator can be attached even to a tilted screen and used widely.

主权项

1. A calibrator selectively attaching to a screen of a display device for calibrating, comprising:
an absorption plate formed of a transformable material, comprising a bottom surface attached to the screen of the display device in a vacuum absorption method; a control portion pulling a first portion of the absorption plate to leave a space between the first portion of the absorption plate and the screen of the display device, wherein the control portion comprises:
a control bracket comprising a control plate coupled to the first portion of the absorption plate and a control rod extending from the control plate in a vertical direction; anda movable frame coupled to an end of the control rod to move in a vertical direction of the display device, when the rotary portion is rotated, and to space the control bracket and the first portion of the absorption plate from the screen of the display device; a fixed portion pressing a second portion of the absorption plate to the screen, wherein the fixed portion comprises:
a fixed plate coupled to a top surface of the absorption plate, the fixed plate comprising a projected portion having a bottom surface in contact with the second portion of the absorption plate and a recessed portion spaced apart a predetermined distance from a first portion of the absorption plate; a rotary portion rotatably coupled to the fixed portion in a horizontal direction of the display device to move the control portion in a vertical direction of the display device, when it is rotated, wherein the rotary portion comprises:
a rotary plate comprising an inclined portion in contact with a lower portion of the movable frame, and the movable frame moves along the inclined portion when the rotary plate is rotated and moves in a vertical direction with respect to the display device; and a circuit unit mounted in the fixed portion to calibrate the color of the display device.
