Abstract

Embodiments of the invention provide an FED (Field Emission Display) pixel driver, an FED display panel and a display device, and relate to the technical field of display. The FED pixel driver comprises a cathode, a drive module, and a modulation and demodulation module. The drive module is connected with the modulation and demodulation module, and is used for providing an opening or closing signal under the control of the modulation and demodulation module. The drive module is further connected with a reference potential input end used for providing reference potential, the cathode, and a grounding end, and is used for driving electrons of the cathode to escape and generate constant emission current in the open state under the control of the reference potential input end and the grounding end. The FED pixel driver, the FED display panel and the display device are used in display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an FED pixel driver, an FED display panel, and a display device. Background technique [0002] Field emission display (English: Field Emission Display, English abbreviation: FED) is adopted, which can combine the high display quality of CRT (Chinese: Cathode Ray Tube, English: Cathode Ray Tube) display and the low In addition, field emission displays are more and more applied to the field of display technology because of their small size, high brightness, large viewing angle, high resolution, wide operating temperature range, and low power consumption. . [0003] Field emission displays in the prior art, such as Figure 1a As shown, it includes a cathode 11 and a gate electrode 12 sequentially located on the lower substrate 10 , and an anode 14 located on the upper substrate 13 . When a certain electric field is applied between the gate electrode 12 and the cathode 11, a large...
