A method and apparatus for driving an electro-luminescence display panel capable of preventing an initial blinking phenomenon occurring at a power application is disclosed. In the method, a first electrode of the EL cell and a ground voltage source are opened during a first period from a turn-on time of a power source to shut off a current path of the EL cells. Then, the first electrode of the pixel matrix and the ground voltage source is shorted during a second period to form a current path such that the EL cells are light-emitted in accordance with a data supplied to the pixel matrix.

Method and apparatus for driving electro-luminescence display panel

An electro-luminescence display device including red, green and blue reference gamma generators each having three digital analog converters or more in order to generate a reference gamma voltage of low gray level and a reference gamma voltage of high gray level, and at least one integrated circuit to generate a data signal in use of the reference gamma voltage of low gray level and the reference gamma voltage of high gray level. Each reference gamma generator includes a first digital analog converter to divide a voltage supplied to itself in order to generate i numbers of voltage levels, a second digital analog converter to divide a voltage supplied to itself in order to generate j numbers of voltage levels, and a third digital analog converter to receive two voltage levels from the second digital analog converter and to divides the two received voltage levels into j numbers of voltage levels.

Electro-luminescence display

The present invention relates to an electro-luminescence display that is adaptive for reducing its manufacturing cost as well as reducing its process time. An electro-luminescence display device according to an embodiment of the present invention includes a gamma generator to output a reference gamma voltage corresponding to a control data supplied from the outside; and at least one data integrated circuit to receive a data from the outside and to generate a data signal corresponding to the bit number of the data in use of the reference gamma voltage.
