Problems solved by technology

[0004] Liquid crystal display has the widest range of applications, but its existing problems are: complex manufacturing process, high precision requirements, high manufacturing cost, smearing phenomenon when displaying dynamic images, and failure to work normally at low temperature, and the power of the light source of the liquid crystal display is fixed. Low backlight utilization
However, laser displays need high-power lasers to achieve the required brightness, which brings heat dissipation problems and high costs; and the thickness of the display is relatively large

Abstract

The invention relates to a straight wave-guide display panel, which comprises a straight waveguide. The ray incident on the straight waveguide is propagated in the way of total reflection. The ray has at least one reflection on each pixel point. After the ray propagation arrives at the selected pixel point, the pixel point will emit out the ray inside the waveguide to form a luminous point and the ray propagation in the said straight waveguide will not be influenced by the unchecked pixel point. Compared with the present technology, the invention has the advantages of simple structure, all-solid-state parts of device, low power consumption and rich colors, which can be made transparent display.
