摘要:
A method including providing a substrate with a gate, a layer of gate insulator material adjacent the gate, and a layer of metal oxide semiconductor material positioned on the gate insulator opposite the gate, forming a selectively patterned etch stop passivation layer and heating at elevated temperature in an oxygen-containing or nitrogen-containing or inert ambience to selectively increase the carrier concentration in regions of the metal oxide semiconductor not covered by the etch stop layer, on which overlying and spaced apart source/drain metals are formed. Subsequently heating the transistor in an oxygen-containing or nitrogen-containing or inert ambience to further improve the source/drain contacts and adjust the threshold voltage to a desired level. Providing additional passivation layer(s) on top of the transistor with electric insulation and barrier property to moisture and chemicals in the surrounding environment.

A method of fabricating MO TFTs includes positioning opaque gate metal on a transparent substrate to define a gate area. Depositing gate dielectric material overlying the gate metal and a surrounding area, and depositing metal oxide semiconductor material thereon. Depositing etch stop material on the semiconductor material. Positioning photoresist defining an isolation area in the semiconductor material, the etch stop material and the photoresist being selectively removable. Exposing the photoresist from the rear surface of the substrate and removing exposed portions to leave the etch stop material uncovered except for a portion overlying and aligned with the gate metal. Etching uncovered portions of the semiconductor material to isolate the TFT. Using the photoresist, selectively etching the etch stop layer to leave a portion overlying and aligned with the gate metal and defining a channel area in the semiconductor material. Depositing and patterning conductive material to form source and drain areas.

A method of fabricating an X-ray imager including the steps of forming an etch stop layer on a glass substrate and depositing a stack of semiconductor layers on the etch stop layer to form a sensor plane. Separating the stack into an array of PIN photodiodes. Depositing a layer of insulating material on the array to form a planarized surface and forming vias through the insulating layer into communication with an upper surface of each photodiode and forming metal contacts on the planarized surface through the vias in contact with each photodiode. Fabricating an array of MOTFTs in an active pixel sensor configuration backplane on the planarized surface and in electrical communication with the contacts, to provide a sensor plane/MOTFT backplane interconnected combination. Attaching a flexible support carrier to the MOTFT backplane and removing the glass substrate. A scintillator is then laminated on the array of photodiodes.

A full-color AM OLED includes a transparent substrate, a color filter positioned on an upper surface of the substrate, and a metal oxide thin film transistor backpanel positioned in overlying relationship on the color filter and defining an array of pixels. An array of OLEDs is formed on the backpanel and positioned to emit light downwardly through the backpanel, the color filter, and the substrate in a full-color display. Light emitted by each OLED includes a first emission band with wavelengths extending across the range of two of the primary colors and a second emission band with wavelengths extending across the range of the remaining primary color. The color filter includes for each pixel, two zones separating the first emission band into two separate primary colors and a third zone passing the second emission band.

A process of fabricating a flexible TFT back-panel on a glass support includes a step of providing a flat glass support member sufficiently thick to prevent bending during the processing. A layer of etch stop material is positioned on the upper surface of the glass support member and an insulating buffer layer is positioned on the layer of etch stop material. A TFT back-panel is positioned on the insulating buffer layer and a flexible plastic carrier is affixed to the TFT back-panel. The glass support member is etched away, whereby a flexible TFT back-panel is provided. The TFT back-panel can include a matrix of either OLED cells or LCD cells.

The present invention provides a wall mounting device and a wall mounting method for liquid crystal display. The wall mounting device includes a cross frame, brackets for supporting a bottom of a liquid crystal display, and connection sections connecting the cross frame and the brackets. The cross frame forms through holes corresponding to the mounting pegs of the liquid crystal display. To assemble, the bottom of the liquid crystal display is positioned on the brackets and the mounting pegs and the through holes are connected to each other so as to couple the liquid crystal display and the wall mounting device together. The wall mounting device for liquid crystal display of that uses brackets to reduce the number of mounting pegs used in the liquid crystal display so as effectively lower down the cost and enable the use of a thinner back frame for the liquid crystal display.

The present invention discloses a connector, which includes a male housing and a female housing. The male housing is formed of three side walls surrounding a circumference of a bottom wall and the female housing is formed of three side walls surrounding a circumference of a bottom wall. The male housing and the female housing are mateable with each other through mutual insertion. Practicing the connector of the present invention may reduce the wall thickness of the connector, making the connector thinner so as to enable use in a backlight module arrangement of relatively small space and provide module designing with more flexibility.

The present invention discloses an LCD device, which includes a display panel, a connecting part, a back cover, and a locking part. The connecting part is fixed on one side of the display panel. The back cover is disposed on the side of the display panel having the connecting part and has a through hole corresponding to the connecting part. The locking part includes a base and an extending portion extending from the base. The base abuts against the back cover, and the extending portion penetrating the through hole and locked in the connecting part, so that the display panel is fixed on the back cover to achieve the LCD device without a bezel.

The present invention provides a frameless liquid crystal display device, which includes a rear enclosure, a backlight module arranged inside the rear enclosure, a mold frame arranged on the backlight module and mounted to the rear enclosure, and a liquid crystal display panel arranged on the mold frame. The liquid crystal display panel has an upper portion that is mounted to the mold frame through a plurality of connection sections. Each of the connection sections includes a cylindrical base plate and a cylindrical projection mounted to the cylindrical base plate. The liquid crystal display panel includes a CF substrate and a TFT substrate laminated on the CF substrate. The CF substrate forms a step with respect to a lower edge of the TFT substrate. A surface decoration is bonded to the step and fixed to the mold frame to assemble the liquid crystal display panel to the mold frame.

A frameless liquid crystal display device includes a rear enclosure, a backlight module arranged inside the rear enclosure, a mold frame arranged on the backlight module and mounted to the rear enclosure, and a liquid crystal display panel arranged on the mold frame. The liquid crystal display panel has upper and lower portions mounted to the mold frame through connection sections, each of which includes a rectangular base plate and a trapezoid block. The mold frame forms a trapezoid slot having an open end and a closed end corresponding to each of the connection sections. The connection section is thus receivable through the open end into the trapezoid slot to retain and fix the liquid crystal display panel to the mold frame. The liquid crystal display panel forms a step and a surface decoration is mounted to the step to fix the liquid crystal display panel to the mold frame.
