An illumination circuit includes a series circuit including light sources connected in series between a high voltage node and a low voltage node, and break-protecting circuits. Each break-protecting circuit includes a control circuit and a bypass circuit. The bypass circuit is connected in parallel to at least one corresponding light source of the light sources. The control circuit is connected to the series circuit and the bypass circuit to detect a voltage change of the series circuit and control the bypass circuit to be in a conduct state or a blocked state according to the voltage change
摘要:
A laser scanning system suitable for annealing applications is described. The problem of keeping the window (through which the laser shines into the system) clean, even though the laser ejects a considerable amount of debris, has been solved by inserting a moveable shutter close to the window between it and the substrate. The center portion of the shutter is an insert of optical quality quartz that is just large enough to allow the laser beam to pass through unimpeded and undiverted. By moving the beam and the shutter in concert it is ensured that the beam always passes through the insert. Most of the debris ejected by the laser as a side effect of its operation is trapped on the shutter. Relatively little material ends up on the quartz insert but when sufficient has accumulated there, the insert can be replaced at much lower cost than replacing the window. By moving the beam back and forth together with movement of the substrate, the entire area of the film on the substrate may be scanned by the beam. In a second embodiment, the quartz insert is omitted and an open slit left in its place. With this arrangement debris will eventually accumulate on the window but at a greatly reduced rate relative to an unprotected window.

The present invention provides a method of forming a liquid crystal display (LCD). Active layers of N-type and P-type low temperature polysilicon thin film transistors and a bottom electrode of a storage capacitor are formed first. Then a N-type source/drain is formed and the bottom electrode is doped with dopants. A gate insulator, a gate electrode, a capacitor dielectric, and a top electrode are thereafter formed. After that, a P-type source/drain is formed. Finally, a source interconnect, a drain interconnect, and a pixel electrode of the liquid crystal display are formed.
