Display panel

Abstract

The invention discloses a display panel, which comprises a front substrate, an optical modulator array, a rear substrate and a backlight source, wherein the lower surface of the front substrate is provided with stripe-shaped scanning electrodes in parallel at equal interval; the upper surface of the rear substrate is provided with stripe-shaped addressing electrodes in parallel at equal interval; and the optical modulator array is packaged between the front substrate and the rear substrate and comprises optical modulators arranged according to the array. The display panel applies the optical modulator array with the optics quantum tunnel effect and inverse piezoelectric effect. When the display panel works, the electrodes on the front substrate and the rear substrate control the optical modulator array to modulate an outer light source provided by the backlight source so as to achieve the purpose of displaying information. The display panel has the advantages of simple manufacture technology and high working efficiency.

Description

technical field [0001] The invention relates to a non-active light-emitting display panel, in particular to a light modulator array using optical quantum tunnel effect and inverse piezoelectric effect. Specifically, it is a display panel that uses a new type of light modulator array to modulate the external light source to achieve the purpose of display. Background technique [0002] At present, electronic displays can be divided into active light-emitting type and non-active light-emitting type. The former uses information to modulate the luminance and color of each pixel for direct display; the latter does not emit light itself, but uses information to modulate the external light source to achieve the purpose of display. In nature, more than 90% of the visual information obtained by humans depends on the reflected light of external objects rather than the light emitted by the object itself, so passive display is more suitable for human vision and less likely to cause eye ...

AI Technical Summary

Problems solved by technology

The working principle of the liquid crystal display panel determines that this device has certain defects: 1, the structure is very complicated, the manufacturing process of the thin film field effect transistor array is high, and the yield is low; 2, because the light emitted by the backlight must pass through a polarizer The device converts natural light into polarized light, so half of the light energy is lost, resulting in low luminous efficiency of the panel, resulting in high energy consumption, and it is gradually difficult to meet the requirements of energy consumption standards; 3. The electro-optic response speed is slow, so in the dynamic The performance of the image is not ideal, and there will be smearing and other phenomena; 4. The light transmission and closing are not complete, that is, the light is still blocked when the state is on, and the light is still transmitted when the state is off, making the contrast of the panel poor; 5. , when the display panel is viewed from various directions, the liquid crystal molecules are arranged differently, resulting in different light transmission, so the viewing angle is small
