Problems solved by technology
[0002] At present, the most common projection methods mainly include CRT projection technology, LCD projection technology and DLP projection technology, but these three methods have their own disadvantages, such as CRT projection technology, which has low brightness, complicated operation and large volume; LCD projection technology Its liquid crystal panel has a short lifespan and is easy to age, resulting in a decrease in brightness and chromaticity, and high maintenance costs; while DLP projection technology uses millions of small micromirrors to reflect and image, and there is no light in the black position of the image. Utilized, and because the flip angle of the small micromirror is fixed, its optical system design is limited and it is difficult to improve

The invention relates to a diode array monochromatic projection imaging device which comprises a diode integrated circuit board, a light emitting diode, a connecting line, a driving control board, and an optical lens group. According to the diode integrated circuit board, a plurality of light emitting diodes are integrated into a PCB, and an M*N array is formed. The driving control board is used for decoding a picture to be projected, the binary value of each point of the array is obtained, and the on and off states of the light emitting diode corresponding to each point is controlled according to a value. The light emitting diode array transmits display picture information to the optical lens group, and the imaging is carried out in an imaging surface. By using the structure of the invention, the picture displayed on the diode integrated circuit board is subjected to the integrated imaging of the lens group, and the imaging precision can be improved significantly.
Description
technical field [0001] The invention relates to the field of imaging devices, in particular to a diode array monochrome projection imaging device. Background technique [0002] At present, the most common projection methods mainly include CRT projection technology, LCD projection technology and DLP projection technology, but these three methods have their own disadvantages, such as CRT projection technology, which has low brightness, complicated operation and large volume; LCD projection technology The life of the liquid crystal panel is not long, and it is easy to age, resulting in a decrease in brightness and chromaticity, and high maintenance costs; while DLP projection technology uses millions of small micromirrors to reflect and image, and there is no light in the black position of the image. However, due to the fixed flip angle of the small micromirror, its optical system design is limited and difficult to improve. Contents of the invention [0003] The technical pr...
