摘要： A method of fabricating a display panel includes providing a first substrate and a second substrate, forming an alignment material layer on one of the first substrate and the second substrate and patterning the alignment material layer to form an individual central portion, forming a hydrophobic surface extending from an edge of the individual central portion toward an edge of the one of the first substrate and the second substrate, forming a sealant material on the one of the first substrate and the second substrate, dropping a display medium material on the individual central portion, assembling the first substrate and the second substrate with the sealant material and curing the sealant material to form a sealant. A gap separates the sealant material from the individual central portion and the hydrophobic surface extends in the gap. The display medium material is restricted by the hydrophobic surface and does not contact the sealant material.

摘要： A display apparatus having a display panel, a humidity DETECTION method thereof and a GAMMA curve calibration method are provided. A humidity detection method and a gamma curve calibration method for the display panel of the display apparatus are also provided. The humidity detection method for the display panel includes: displaying a test pattern via the display panel; projecting an incident light to the test pattern of the display panel via a light source to generate a diffraction light; and detecting the diffraction light via a light detector to obtain a humidity information of the display panel. Therefore, a gamma setting of the display panel may be adjusted via the humidity information of the display panel.

摘要： A display panel includes a first substrate, a second substrate, a display medium layer, a sealant and a conductor. The first and second substrates are assembled via the sealant that surrounds the display medium layer disposed between the first and second substrates. The second substrate includes a second conductive layer and a passivation layer disposed on the second conductive layer. The passivation layer reveals a portion of the second conductive layer. The conductor electrically connects a first conductive layer of the first substrate to the revealed portion of the second conductive layer and is disposed between the sealant and an edge of the display panel. A first conductive protrusion and a second conductive protrusion are sequentially disposed on one of the first and second substrates to form the conductor. A material of the second conductive protrusion may be formed from a conductive composite material, that may include a curable material.

摘要： A display panel according to an embodiment has a first region surrounding a second region. The display panel includes a top substrate, a bottom substrate opposite to the top substrate, a sealant located within the first region, and a display medium layer encased by the top substrate, the bottom substrate, and the sealant. A patterned light shielding layer is disposed on an upper surface of the top substrate in the first region. A light filtering layer is disposed on the top substrate in the second region of the display panel. The light filtering layer causes a reduction of a transmittance of light of wavelength ranged from about 300 nm to about 410 nm by at least about 20% to about 50%, and a transmittance of the light filtering layer for light of wavelength ranged from about 450 nm to about 800 nm is at least about 80% to 95%.
