  • Publication number: 20230197907
    Abstract: A display apparatus includes a micro-light-emitting device comprising at least two device-side electrodes, a driving substrate comprising at least two driving substrate-side electrodes, and at least two metal layers, each metal layer being interposed between a corresponding device-side electrode and a corresponding driving substrate-side electrode, and connecting the corresponding device-side electrode to the corresponding driving substrate-side electrode. A distance between adjacent driving substrate-side electrodes, among the at least two driving substrate-side electrodes, is greater than a distance between adjacent device-side electrodes, among the at least two device-side electrodes, and each metal layer of the at least two metal layers is a metal formed by undergoing heating without pressure applied thereto and then curing during a process of connecting the at least two device-side electrodes to the at least two driving substrate-side electrodes.

  • Patent number: 6680568
    Abstract: A light emitting device effectively utilizes the light emanating from a semiconductor luminous element, and can acquire clear and high-luminance light emission without a color dapple. The light emitting device is configured as follows. A transparent resin containing a wavelength converting material is provided on a reflecting surface of a base member such as a case, a board and a lead frame. The transparent semiconductor luminous element is bonded and fixed on the transparent resin. A wavelength of light emitted from a lower surface of the semiconductor luminous element is converted by the wavelength converting material, and the converted light is reflected on the reflecting surface. The reflected light is mixed with light emitted from an upper surface of the semiconductor luminous element, and the mixed light is radiated.
