Abstract: PURPOSE: A method for driving LCD(liquid crystal display) is provided to minimize a screen distortion of a border between an upper part and a lower part when LCD is driven in two parts being upper and lower parts, by changing a driving sequence of a gate line, and makes the same data voltage charge time point of the upper and lower border parts. CONSTITUTION: A method for driving LCD having M gate lines and N data lines drives the data lines in upper and lower parts. A time difference between the driving starting points of adjacent gate lines of the upper and lower border parts of screen is smaller than 2 horizontal period. M gate lines are sequentially driven. The M gate lines are driven in the upper and lower parts, and the gate lines adjacent to the upper and lower border parts are simultaneously driven. Thereby, a screen distortion of a border between an upper part and a lower part is minimized.

Abstract: PURPOSE: An apparatus for connecting a battery pack of a wireless terminal is provided to miniaturize the wireless terminal by using one part of backside of the wireless terminal body, to supply a stable connection structure by applying a point-to-point connection, and to prevent water from permeating into the wireless terminal by configuring the apparatus with water-proof structure. CONSTITUTION: If a battery pack(200) is attached to a pack groove of a body frame(120), the battery pack maintains a locking state by connections among a locker, a connector(132), a mounter, and a holder of the pack groove. The battery pack is connected with printed circuit boards(PCBs)(70), and a connection between the PCBs is maintained by a first connector and a second connector. The first connector is a contact assembly(60). The contact assembly is composed of a housing, a first terminal(601), and a compressing coil spring. The housing is composed of a conductive material. The first/the second terminals are conductive. The second connector is composed of a battery contact(61) and a battery contact tail(62). The battery contact is connected with the contact assembly by a point-to-point type. The battery contact tail is connected with the battery contact by the point-to-point type. The battery contact tail and a battery cell are electrically connected by a flexible printed circuit board(FPCB)(63).
