[0020] In addition, the IC provided inside the container portion is bonded to the substrate by die bond paste, but considering the heat resistance of the IC, the firing temperature of the die bond paste is set to be lower than that of the phosphor layer. The firing temperature is about 480°C lower than 510°C. Therefore, the gas may not be completely released from the die-bonding paste during firing, and the gas may be released from the die-bonding paste during subsequent use and become a container The reason for the further decrease of the vacuum degree in the interior

The present invention provides an IC-embedded fluorescent display device. In the fluorescent display device with a control IC in a dent part of a container part, the vacuum degree in the container part is improved to a higher service life characteristic. The container part (2) of the fluorescent display device (1) has a structure in which an anode substrate (4) with an anode (7) and a cathode substrate (3) with a cathode (10) are separately provided with a preset distance and the outer edge is sealed circumferentially with the sealing material (6). An internal surface of the cathode substrate is provided with a dent part (20), and the IC (21) provided on the anode substrate is accommodated in the dent part. The inner part of the container part is hermetically divided into a first part (A) with an anode and a cathode, and a second part (B) with the dent part and the IC through a dividing wall (15). The inner dimension of the dent part is larger, but the part (A) divided by the dividing part is smaller. Higher vacuum degree can be obtained through non-evaporation type getter.
Description
technical field [0001] The present invention relates to a fluorescent display device with a built-in IC in which a recess is formed on the inner surface of a container for accommodating an anode having a phosphor layer and a cathode for releasing electrons, and a control IC is installed in the container using the space of the recess. This is a fluorescent display device with a built-in IC that can achieve a longer life by increasing the volume inside the container due to the formation of the recess and increasing the vacuum in the container. Background technique [0002] There is known a fluorescent display device in which an anode having a phosphor layer and a cathode emitting electrons are provided in a container, and electrons are emitted from the cathode to shoot toward the phosphor and emit light to perform display. As a fluorescent display device having such a basic structure, there are known types that use a filament in the cathode to release thermal electrons, and a ...
