Problems solved by technology

However, the image drive circuit in the above-mentioned FED drive circuit system is separated from the gray-scale modulation signal generator and the pulse amplifier, and the pulse amplifier adopts a discrete drive circuit structure, and many discrete devices are used, so the circuit structure is complex and cumbersome. The disadvantages of large circuit size, large power loss and low stability, and the above-mentioned FED drive circuit can only achieve monochrome video images

Embodiment Construction

[0024] Such as Figure 1 to Figure 7 Shown, the present invention is made up of parts such as video receiving unit, video A / D conversion unit, data cache unit, integrated gray-scale modulation drive unit, line post-level integrated drive unit, FPGA control module unit and power supply module, and video signal is made up of The video receiving unit sends the video A / D conversion unit for A / D conversion after receiving, and then sends the data buffer unit for storage and interception, takes it out and sends it to the integrated grayscale modulation drive unit to complete grayscale modulation and amplification, and then transmits it to the FED screen for display. At the same time, the post-row integrated drive unit sends the amplified row signal to drive the FED screen, and the FPGA controls the data buffer unit, integrated grayscale modulation drive unit, and post-row integrated drive unit. The working principle of its circuit is to send the analog video image signal of PAL stan...

Description

technical field [0001] The patent of the invention belongs to the technical field of display manufacturing, and in particular relates to a video drive circuit for a field emission display device. Background technique [0002] Field emission display (FED) is a relatively new type of flat panel display, and it is another most promising new type after liquid crystal display (LCD), plasma display (PDP), electroluminescence display (ELD), etc. A generation of flat panel displays. The large-area printed FED developed by our company uses a unique low-cost large-area low-work function FED cathode material and its cathode slurry, and has independent intellectual property rights. Different from other types of FEDs, large-area printed FEDs are low in cost and simple in process, and the materials used have low work function characteristics, which can reduce the required emission voltage in the FED and simplify the external circuit. At present, we have developed a 25-inch color large-s...
