A display with high resolution and reduced flicker of image. The phosphor is disposed on a support that has a reflective substrate comprising a continuous poly first phase and a second phase dispersed within the continuous poly first phase. Temperature sensors are disposed on the lid to measure temperatures of hot spots of the integrated circuit. A latch supported by the enclosure and extending from the window opening can be used to engage with the insert portion to automatically retain the support arm when the insert portion is inserted into the window opening. According to the invention, exo-1–3-piperidino-1-propanone can be obtained by reacting the exo-ether of enol silylene of formula with a compound of N-methylenepiperidinium. In particular, a pivot base is configured on one side of the hollow frame, which is pivotally connected another pivot base on the cover side with a connecting arm for fixedness.
