  • Patent number: 10838540
    Abstract: A touch control device with ESD protection includes a touch display panel, a switching unit, a touch electrode and a ground electrode. An ESD protection electrode is provided around at least one periphery of the touch display panel. A scanning period of the ESD protection electrode is divided into touch periods and ESD periods. When the scanning period of the ESD protection electrode is during the touch periods, the ESD protection electrode is used as touch electrodes for sensing touch events made by a user on the touch display panel. When the scanning period of the ESD protection electrode is during the ESD periods, the ESD protection electrode is used as ESD protection electrodes for dissipating ESD on the touch display panel in order to protect signal elements inside the touch display panel. The ESD protection electrode is therefore used for not only ESD protection, but also touch sensing.

  • Publication number: 20180175321
    Abstract: A transparent organic light emitting diode (OLED) includes a transparent substrate; transparent anodes on the transparent substrate and bridged by an insulating layer; at least an isolation pillar provided above the insulating layer; an organic light emitting layer coated on the surfaces of the transparent anodes and the isolation pillars; and a metal cathode coated on the surfaces of the organic light emitting layer on the transparent anodes. When light passes through the transparent OLED, only the areas where the metal cathode is coated will affect the light transmittance, and the rest of the areas not coated with the metal cathode may maintain a better transmittance. By reducing the coating area of the metal cathode, the transparent OLED is able to increase its transmittance accordingly.

  • Patent number: 9653530
    Abstract: An OLED module equipped with vertical electric connection structure includes a substrate, a plurality of OLED clusters, an anode wire structure and a cathode wire structure. The substrate is extended toward a first direction. The OLED clusters are located on the substrate in the first direction. The anode wire structure includes a bottom layer wire set, an insulation layer, a middle wire layer set and a top layer wire set. The bottom layer wire set is located on the substrate. The insulation layer is located on the bottom layer wire set. The top layer wire set is located on the insulation layer. The cathode wire structure is located on the substrate and extended axially thereof. The middle layer wire set runs through the insulation layer and forms vertical connection between the bottom layer wire set and the top layer wire set.

  • Publication number: 20170040391
    Abstract: An organic light emitting diode (OLED) module with optical signal transmission includes a substrate, an OLED element, an optical signal transmission element and a spacing member. The substrate includes a light emitting region, an optical transmission region, and a spacing region spaced between the light emitting region and an optical transmission region. The OLED element is disposed in the light emitting region, and includes a first electrode layer, a second electrode layer and an organic light emitting layer. The optical signal transmission element is disposed in the optical transmission region and transmits an optical signal to the exterior. The spacing member is disposed in the spacing region, and includes a lower portion and an upper portion having a width greater than that of the lower portion. Thus, the present invention provides a simplified manufacturing process, a reduced overall volume and lowered production costs.

  • Publication number: 20160343778
    Abstract: A severable organic light-emitting diode module includes a substrate, a first electrode located on the substrate, an organic light-emitting element layer, an electric connection element, an insulation wall and a second electrode. The organic light-emitting element layer is located on the first electrode and includes a bottom surface, a top surface and a through hole run through the bottom surface and the top surface. The electric connection element is located in the through hole and has a bottom portion in contact with the first electrode and a top portion extended over the top surface. The insulation wall is located between the electric connection element and the organic light-emitting element layer. The second electrode is located on the top surface. The second electrode and the top portion of the electric connection element are located at an electric connection side higher than the top surface of the organic light-emitting element layer.
