Abstract: PURPOSE: A fluorescent screen of a color cathode ray tube is provided to improve productivity and to enhance characteristics. CONSTITUTION: A fluorescent screen of a color cathode ray tube includes a glass panel(1) on which a black matrix layer(11) is formed. In addition, three fluorescent layers, namely, a blue layer(7B), a green layer(7G) and a red layer(7R) are formed on the glass panel(1). In particular, a blue filter layer(6B) is formed between the blue fluorescent layer(7B) and the black matrix layer(11), however other color filter layers are not formed. Instead of filter layers, a corresponding pigment is applied to the green layer(7G) and the red layer(7R). By employing a green or red fluorescent body to which a green or red pigment applied, without adding a filter layer, it is possible to minimize a lowering of luminous brightness. Therefore, since a filter forming step is not necessary, productivity is considerably improved.

Abstract: PURPOSE: A data strobe buffer of a synchronous DRAM is provided to prevent the mis-operation of a chip by a damping of a data strobe(DS) signal. CONSTITUTION: A synchronous DRAM uses a data strobe signal. If a data strobe signal(DS) is damped in a data strobe buffer, a pulse made by receiving a falling edge of the data strobe signal induces a mis-operation of a chip. Thus, a dynamic buffer making the pulse by receiving the falling edge of the data strobe signal is constructed to operate only for a specific range, that is, from a rising edge of an external clock(CLK) to the falling edge of the data strobe signal. The damping of the data strobe signal is occurred at a point after the last falling edge of the data strobe signal, and if this point is after the rising edge of the external clock, there will be no problem in the operation of the chip. Thus, because the dynamic buffer does not operate during the interval from the falling edge of the data strobe signal to the rising edge of the external clock, there is no unnecessary output.
