A display device that includes: a glass substrate comprising a refractive index (n); a display device structure coupled to the substrate to collectively define a viewing area; and a black mask structure surrounding the display device structure that is coupled to the substrate and comprises a black ink layer and at least one glossy layer between the black ink layer and the glass substrate. The viewing area is characterized by (a) a reflectance from 0.5% to 2.5% as measured at 8 degrees from normal in the visible spectrum, (b) a brightness in the CIE colorimetry system such that 5<L*<17 for the specular component included (SCI), and (c) a brightness in the CIE colorimetry system such that 0<L*<3 for the specular component excluded (SCE). Further, the at least one glossy layer comprises a refractive index (n) such that |n−n|>0.1.

Display devices and articles with color-matched display and non-display areas

A sealing device and method are described herein that can be used to manufacture a hermetically sealed glass package. In one embodiment, the hermetically sealed glass package is suitable to protect thin film devices which are sensitive to the ambient environment (e.g., oxygen, moisture). Some examples of such glass packages are organic emitting light diode (OLED) displays, sensors, and other optical devices. The present invention is demonstrated using an OLED display as an example.

System and method for frit sealing glass packages

A method for manufacturing a hermetically sealed package is provided, the method comprising the steps of: using a laser to heat a frit, disposed in a pattern between two substrates, such that the heated frit forms a hermetic seal which connects the substrates and further comprising: directing the laser to enter the frit pattern, then to trace the frit pattern, then to retrace a portion of the frit pattern, and then to exit the frit pattern; and selecting an initial laser power which, when the laser enters the frit pattern, is insufficient to heat the frit to form a hermetic seal; then increasing the laser power over a first section of the frit pattern to a target laser power at least sufficient to heat the frit to form a hermetic seal; and then decreasing the laser power over a second section of the frit pattern until the laser power is insufficient to heat the frit to form a hermetic seal before the laser exits the frit pattern.

Hermetically sealed glass package and method of manufacture

A method of encapsulating a display device between substrates with a glass frit. The method includes depositing a frit having an optical absorption &#x3b1; which is a function of wavelength onto a first substrate wherein the deposited frit has a height h, placing a second substrate in contact with the frit, sealing together the substrates by traversing a laser light having a wavelength &#x3bb; over the frit at a speed greater than about 5 mm/s, and wherein &#x3b1;&#xb7;h at &#x3bb; is between 0.4 and about 1.75.

Method of encapsulating a display element

A method of minimizing stress in an OLED device laser sealing process using an elongated laser beam. A laser beam having an intensity distribution which decreases as a function of distance from the longitudinal axis of the beam is passed through a mask to create an elongated beam having a length-wise intensity distribution which decreases as a function of distance from the axis of the beam and a substantially constant width-wise intensity distribution. The elongated beam is traversed over a line of frit disposed between two substrates. The tails of the length-wise intensity distribution provide for a slow cool down of the frit as the beam traverses the line of frit.

Method of encapsulating a display element with frit wall and laser beam

A hermetically sealed glass package and method for manufacturing the hermetically sealed glass package are described herein. In one embodiment, the hermetically sealed glass package is suitable to protect thin film devices which are sensitive to the ambient environment. Some examples of such glass packages are organic emitting light diode (OLED) displays, sensors, and other optical devices. The present invention is demonstrated using an OLED display as an example.

Optimization of parameters for sealing organic emitting light diode (OLED) displays

The present invention provides methods for measuring Fe (II) and Fe (III) levels in a glass composition, for using those measured levels for determining a relative oxidation state of the glass material, and for further making a determination based on those measurements as to the quality of the glass material. In addition, methods are presented for determining the reliable quality of ultra fine/ultra thin glass in the time and labor efficient manner.
