Abstract: A micro LED display panel includes a plurality of active areas disposed on a substrate and arranged in an array. A plurality of micro LEDs are uniformly arranged in each of the active areas to achieve high-resolution of micro LED display panel. By controlling the number of micro LEDs in each of the active areas, the production cost can be effectively controlled, while a screen door effect can be eliminated to thereby enhance market competitiveness of the micro LED display panel.

Abstract: Disclosed is a method for regulating color shift in white balance procedure of a four-color display device. The method includes steps of: obtaining brightness of a white color displayed by a combination according to stimulus values Y of a red sub pixel unit, a green sub pixel unit, a blue pixel unit, and a fourth sub pixel unit; and balancing a white color and one shifting color/two shifting colors/three shifting colors using a weighting factor in case of a two-color balance, a three-color balance, or a four-color balance.

Abstract: An overdrive method of a four-color panel is disclosed. The method comprises searching 10% brightness value point and 90% brightness value point in a normalized curve, calculating difference between R (or B) brightness normalized curve and G brightness normalized curve ranging from 10% brightness value point to 90% brightness value point, and determining each RIG overdrive gray-scale voltage value in an overdrive gray-scale voltage table through evaluating a minimum value of the difference between brightness normalized curves. The obtained changed R/G/B overdrive target values are substituted into a formula for calculating W overdrive target value between different gray-scales.

Abstract: An OLED display device includes a substrate, an OLED layer located on the substrate, and a quantum dot package layer covering the OLED layer. The quantum dot package layer includes a quantum dot material. Blue light or white light emitting from the OLED layer excites the quantum dot material of the quantum dot package layer to emit light for color displaying with high color gamut.

Abstract: An LCD device is provided. The liquid crystal panel thereof includes first and second substrates (opposite each other). The first substrate sequentially includes a first underlay-substrate, a quantum-dot color filter, and an encapsulation layer. The quantum-dot color filter includes a pixel separation layer and several color resist units which are separated by the pixel separation layer, and include first, second and third color resist units, where at least one is a quantum-dot color resist unit. There is a transparent stacked layer between the quantum-dot color resist unit and the encapsulation layer in the quantum-dot color filter, thus the quantum-dot color resist unit has a higher standing point than the pixel separation layer on the encapsulation layer. The phenomenon of the brightening and color deviation of the black screen of the liquid crystal display device at the time of a large viewing-angle displaying can be prevented to enhance display effect.

Abstract: The present invention provides a micro transfer printing method, which uses pick-up projections provided on a transfer head to suck and hold micro components arranged on a carrier plate, followed by reversing the transfer head and the carrier plate to make the transfer head positioned under the carrier plate, and then separates the transfer head and the carrier plate from each other to allow the micro components that are sucked and held by the pick-up projections to be carried by and supported on the transfer head, and then moves the transfer head that carries thereon the micro components to a location above a receiving substrate and turning the transfer head up side down to allow the micro components that are held on the pick-up projections to be positioned on the receiving substrate. In the micro transfer printing method of the present invention, during the course that the transfer head transfers the micro components, the micro components are carried by and supported on the transfer head and compared to the prior art, holding the micro components on the transfer head does not require any means to overcome influence caused by the gravity so as to ensure stable and smooth transfer of the micro components by the transfer head to thereby allowing for fast movement of the transfer head and thus effectively increasing transfer rate and speed of the transfer head.

Abstract: The present invention provides a method for manufacturing a flexible array substrate. The method includes, first, successively forming an adhesive layer, a passivation layer, a back-side drive circuit, a planarization layer, a flexible backing plate, and a front-side drive circuit and a display circuit, in a stacked arrangement, on a rigid support plate and then peeling off the rigid support plate and the adhesive layer to form a flexible array substrate having a double-sided circuit structure. The entirey process requires no steps of peeling, reversing, and then re-attaching of the flexible backing plate so that it is possible to avoid the issues of poor flatness and low yield resulting from improper or wrongful re-attachment of the flexible backing plate and thus, fabrication difficulty of a flexible array substrate having a double-sided circuit structure may be lowered down to thereby improve fabrication yield of the flexible array substrate.
