A back-end energy storage isolation fly-back conversion apparatus () includes a return switch (Q), a driving switch (Q), an energy storage capacitor (Cs), a transformer (T), a resonant inductor (Lr), a first rectifier (), an output capacitor (Cout), and a controller (). The transformer (T) includes a primary-side winding (Lm) and a secondary-side first winding (). The return switch (Q) is turned on by the controller (), so that the energy storage capacitor (Cs) is charged by a primary-side current (I) flowing through the resonant inductor (Lr), the primary-side winding (Lm), and the return switch (Q), and the secondary-side first winding () is powered by the primary-side current (I). When the primary-side current (I) becomes negative, the energy storage capacitor (Cs) discharges through the return switch (Q) and the primary-side winding (Lm) and continuously supplies power to the secondary-side first winding ().

Back-end energy storage isolation fly-back conversion apparatus

A light emitting diode module structural and a manufacturing method thereof are disclosed. The manufacturing method includes the steps as follows. A base and a light emitting diode die are provided. The light emitting diode die may include a first semiconductor layer and a second semiconductor layer. The light emitting diode die is disposed on the base. A buffer layer is formed to cover the light emitting diode die. A first opening and a second opening are formed on the first semiconductor layer and the second semiconductor layer, respectively. The second opening exposes the second semiconductor layer by penetrating the first semiconductor layer. A conductive pattern layer is formed on the buffer layer, and is electrically connected with the first semiconductor layer and the second semiconductor layer via the first opening and the second opening, respectively.

Light emitting diode module structure and manufacturing method thereof

The present invention provides a color LCD, which comprises a first substrate and a second substrate with a liquid crystal layer sandwiched in between and a seal-ring for sealing them. The seal-ring has conductive spacers. Transparent electrode plates cover two opposed surfaces of the two substrates, respectively. The seal-ring having conductive spacers is used to conduct the two transparent electrode plates. A color filter is disposed between the first substrate and the transparent electrode plates. The color filter has a plurality of pixels disposed thereon. Each of the pixels comprises at least two sub pixels, and each of the sub pixels is composed of at least two colors. Conductive walking lines on the transparent electrode plates are used to electrically connect at least two data transmission lines of the same color in each column of longitudinally-arranged pixels to the same pin.
