Latest Patents
Chung I Tan holds a patent for a "Thick film print head structure and control circuit." This invention presents a new structure for a thick-film thermal printhead, along with various implementation approaches for controlling such a printhead. The design features a conductive lead at each end of the heater element that can be switched to either the power supply or ground, depending on the corresponding nib data bit. This improvement over traditional center-tap structures reduces the density of conductive leads, achieving higher resolution in printed dots. Unlike previous printhead structures that suffered from undesirable leaking currents, Tan's design eliminates leakage current completely. The control of the thermal printhead is based on a sequential exclusive-OR (XOR) logic operation applied to the shifted-in nib data bit stream. This functionality can be integrated into the driver IC, embedded in the raster data processing FPGA, or implemented as a lookup table in the main processor system's memory block. The new driver IC features SPDT switches and built-in XOR gates that can operate in pass-through mode, allowing it to function as a traditional driver IC.
