Abstract: An electronic device is provided with a display such as a liquid crystal display. The display has a layer of liquid crystal material sandwiched between an upper display layer such as a color filter layer and a lower display layer such as a thin-film-transistor layer. An upper polarizer is formed on the upper surface of the color filter layer. A lower polarizer is formed on the lower surface of the thin-film-transistor layer. To protect display layers such as the color filter layer and the thin-film-transistor layer, a coating is deposited on a peripheral edge of the display layer. A laser is used to cut through portions of the polarizer that overhang the display layer while also cutting through the coating on the peripheral edge of the display layer. Following laser trimming operations, the coating is flush with an edge surface of the polarizer.

Abstract: A display may have a liquid crystal layer sandwiched between a thin-film transistor layer and a color filter layer. An upper polarizer may be placed on top of the thin-film transistor layer. A lower polarizer may be placed under the color filter layer. Components may be bonded to bond pads on the inner surface of the thin-film transistor layer using anisotropic conductive film. Bond quality may be assessed by probing probe pads that are coupled to the bond pads or by visually inspecting the bond pads through the thin-film transistor layer. Opaque masking material in the inactive area may be provided with openings to accommodate the bond pads. Additional opaque masking material may be placed on the underside of the upper polarizer and on the upper surface of the thin-film transistor layer to block the openings from view following visual inspection.

Abstract: A display such as a liquid crystal display has a display substrate that includes a layer of liquid crystal material sandwiched between a color filter layer and a thin-film-transistor layer. An oversized polarizer is laminated to the surface of the display substrate. Laser-based polarizer trimming equipment is used to trim away excess portions of the polarizer from the display substrate. A thickness gauge gathers thickness information from the laminated polarizer and display substrate. The thickness information is used to adjust the position of a laser relative to the polarizer during polarizer trimming operations. The laser beam moves along a cutting path that is unique to the display substrate. A vision system performs an inspection to determine whether the display substrate is damaged following polarizer trimming operations. Based on the inspection, laser parameters may be adjusted prior to performing polarizer trimming operations on additional polarizers and display substrates.

Abstract: Embodiments include systems and methods for objectively grading/rating a display. One embodiment may take the form of a method for grading display quality including capturing an image of the display and computing first and second parameter values from the captured image. The method also includes comparing the first parameter value against a threshold and, if the first parameter value exceeds the threshold, computing a grade wherein the second parameter is given a first weighting. If, however, the first parameter value is below the threshold, the method includes computing a grade wherein the second parameter is given a second weighting which is greater than the first weighting.
