Abstract: A display panel includes a color filter (CF) substrate including first support structures, a thin film transistor (TFT) substrate including second support structures, and a liquid crystal layer. Each of the first support structures resists against the TFT substrate, and each of the second support structures resists against the CF substrate to form a receiving space between the CF substrate and the TFT substrate, the receiving space contains the liquid crystal layer. The TFT substrate applies driving signals to the liquid crystal layer to modulate backlight received by the liquid crystal layer from a backlight source. The CF substrate allows light to be emitted as images by filtering the modulated backlight.

Abstract: A liquid crystal display panel which is viewable from a greater range of oblique viewing angles without apparent loss of contrast or color intensity includes a thin film transistor substrate, a color filter substrate, a liquid crystal layer between the color filter substrate and the thin film transistor substrate. The color filter substrate includes a glass substrate, a black matrix, and a color filter layer on the glass substrate. A surface of the glass substrate defines a plurality of grooves having different depths. Both the black matrix and the color filter layer are in the grooves. A thickness of the liquid crystal layer changes with depths of the plurality of grooves. A display device and a method for making the liquid crystal display panel are also provided.

Abstract: A mass transfer system comprises a flexible substrate, a display substrate, and an attaching device. The flexible substrate defines a plurality of wells configured to adsorb one of a plurality of LEDs. The display substrate defines a plurality of connecting pads configured to bond one of the LEDs. The attaching device is configured to attach the flexible substrate to the display substrate. The flexible substrate releases the LEDs after being attached to the display substrate to transfer the LEDs to the display substrate. An attaching device and a mass transfer method are also disclosed.

Abstract: A method and system for rapid and efficient mass transfer of a quantity of micro LEDs from storage onto a display substrate provides a micro LED which includes an electrode part, a luminous part, and a suspending part. The electrode part includes at least one electrode. The luminous part emits a certain color of light. The matter density of the suspending part is reduced to be less than that of a liquid holding the quantity of micro LEDs in suspension, and also less than the matter density of the other two parts of the micro LED. Even before illumination, the suspending part has the same color as the color of light to be emitted by that micro LED. A mass transfer system and a mass transfer method are disclosed.
