Abstract: A display device includes a display panel, a backlight module and a reel. The backlight module faces the display panel and includes a light transmissive region, a light emitting region and a peripheral region, in which the peripheral region is disposed between the light transmissive region and the light emitting region. The light transmissive region includes a first edge extending along a first direction and a second edge extending along a second direction. The backlight module includes a first brightness enhancing film including first microstructures arranged along the first direction. The first microstructures that pass through the peripheral region without connecting to the first edge have less light gathering efficiency than the first microstructures that only pass through the light emitting region. The reel faces the light transmissive region, and the display panel and the reel are respectively located on opposing sides of the backlight module.

Abstract: Disclosed is a servo control method and apparatus for use on discharging machines to control the discharging conditions on working piece. In conventional art, feedrate control is based on the average of the discharging voltage between the discharging electrode and the working piece, which takes the off-time period into account; and in the condition of a long off-time period, the average voltage will be lowered as to affect the stability of the discharging process. The servo control method and apparatus according to the present invention disregards the off-time period and takes only the ignition voltage and discharging voltage into account such that the stability of the discharging machine will not be affected. Furthermore, during discharging, the servo control method and apparatus is capable of detecting whether there is a short-circuit condition and adjusting the average voltage accordingly so as to quickly remove the discharging electrode from the working piece.
