Abstract:
A successive approximation analog-to-digital converter is used for converting an analog input signal into a corresponding digital output signal. The successive approximation analog-to-digital converter has a successive approximation register for storing a first digital bit stream and a second digital bit stream that are related to the analog input signal, and a digital-to-analog converter for generating a first reference voltage and a second reference voltage according to the first and second digital bit streams. The digital-to-analog converter has a first voltage divider and a second voltage divider. The first voltage divider drives the first reference voltage approaching the analog input signal to establish the first digital bit stream, and the second voltage divider drives the second reference voltage approaching the analog input signal to establish the second digital bit stream. Finally, the first and second digital bit streams are averaged to generate the digital output signal.

Abstract:
A field emission device has pixels with cathode and anode provided on the same plane, so that electrons directly penetrate an independently provided fluorescent powder layer to produce light, giving the display the advantages of easy focusing, no dark spots, high brightness, and enhanced light emitting performance. Since the light produced by the fluorescent powder layer is not blocked by the anode, the problem of charge accumulation on the fluorescent powder layer is avoided, and it is not necessary to use expensive light-transmittable conducting glass as the anode. With the cathode and the anode located at the same plane, it is not necessary to use a high precision spacer to maintain a fixed distance between the cathode and the anode, enabling the device to be manufactured at reduced cost and high good yield.

The casing includes a lower base and an upper cover both provided with a transparent region respectively. The light-emitting module is received in the casing and has light-emitting diodes arranged in a strip. The reflecting element is mounted in the casing to correspond to the transparent regions. The reflecting element has a first reflecting surface and a second reflecting surface both located on one side of the light-emitting diodes. The light generated by the light-emitting diodes is reflected by the first and second reflecting surfaces to exit the transparent regions. The power supply unit is received in the casing to be electrically connected with the light-emitting module. Thus, the light of the light-emitting diodes can be emitted out of the casing in two directions.
