The present invention discloses a direct type backlight module and a Liquid Crystal Display device. When transmitting a response signal to the master station, each slave station generates not only a time slot number but also a time delay number. The rod has an outer surface, a generally circular cross-section perimeter, a center axis, a proximal end with a user input, and a distal end configured to directly or indirectly interact with an apparatus to be controlled. If the database object is inconsistent, a first pessimistic read is performed with an isolation level that does not guarantee consistency. At least one of the sidewalls includes a recession to receive and support the fishing pole. At least one electrode which is at a positive potential with respect to the pressure stage aperture and is adapted to deflect the secondary electrons from the specimen to the detector may be arranged above the bottom pressure stage aperture.
