Problems solved by technology

[0003] However, in actual use, the light transmittance of the panel cannot reach 100%, and a large part of the light that fails to pass through is scattered from the gap between the panels, forming light leakage, affecting the look and feel of the display screen, and limiting the development of thinner and smaller displays. The development of the frame; on the other hand, it also wastes light energy
[0004] Disadvantages of the prior art: easy to leak light, low utilization rate of light energy

Abstract

The invention discloses a photovoltaic effect-based LTPS display panel energy recovery structure. The display panel comprises a panel substrate (1), a liquid crystal layer (2) and a polarization layer(3) sequentially from inside to outside, wherein a pixel dot array is etched on the panel substrate (1). The display panel is characterized in that the panel substrate (1) is also provided with N photovoltaic conversion units (1b); each photovoltaic conversion unit (1b) is attached to a pixel dot (1a) of the pixel dot array; the N photovoltaic conversion units (1b) are connected with an externalpower storage mechanism (4); and the power storage mechanism (4) is used for gathering and storing photovoltaic converted electrical energy. The photovoltaic effect-based LTPS display panel energy recovery structure has the beneficial effects that light scattered by the substrate is converted into electrical energy for being stored through photovoltaic effects, on one hand, transparency of a normal pixel dot is not influenced, and on the other hand, the scattered light is reduced, the light leakage is reduced, and the energy is recovered to improve the light energy utilization rate.
