Display panel and manufacturing method thereof, display device and color reproduction method thereof, and electronic device

Abstract

The present invention provides a display panel, comprising: a substrate, a first reflective layer and a translucent second reflective layer; the first reflective layer includes an array of reflective units; the reflective unit includes: The frame is a reflective plate surrounded by the frame, which can move continuously along the direction perpendicular to the first reflective layer, and connects the frame and the support beam of the reflective plate. The invention also provides a manufacturing method of the display panel, a display device and its color restoration method, and an electronic device. The display panel synthesizes colors through sequential colors without distinguishing pixel colors, and the manufacturing process is only one-third of the traditional display panel manufacturing method, and has the characteristics of simple structure, easy manufacture, and low manufacturing cost. The display device provided by the present invention can compensate the color drift caused by manufacturing errors, and transfer the task of accurately realizing color restoration from the manufacturing process to the peripheral circuit of the display panel, thereby reducing the requirement for manufacturing process precision.

Description

technical field [0001] The invention relates to the technical field of color display, in particular to a display panel and a manufacturing method thereof, a display device and a color restoration method thereof, and an electronic device. Background technique [0002] Flat panel displays have developed rapidly in recent years due to their small size and light weight. Reflective flat-panel displays use natural light from the outside to form reflected light on the display panel without using a backlight, so they consume less power and can be used directly under strong light, especially suitable for mobile phones and personal digital assistants (PDAs). , portable computers and other portable products. [0003] At present, the display principles of reflective flat panel display technology include: the principle of electrophoresis or electrowetting, the principle of bistable liquid crystal light diffraction, and the principle of light interference. The reflective flat panel disp...

Problems solved by technology

Usually, the lower surface of the first conductive layer 11 and the upper surface of the transparent layer 15 are in contact with each other after the voltage is applied, and the voltage is removed under normal conditions, and the lower surface of the first conductive layer 11 and the upper surface of the transparent film layer 15 are due to the second conductive layer. 13 separated by the elastic force, but because of the above-mentioned adhesion problem, even if the voltage is removed between the planes, it still cannot restore its original state, so that the display cannot work normally or even be scrapped

[0009] Moreover, each display unit in the prior art has only two states of "off" and "bright", and the displayed color (that is, the wavelength λ of the light that interferes with intensification) 0 ) is determined by the width D of the gap 14, the dielectric material and the thickness d of the transparent layer 15, in other words, the manufacturing accuracy of the gap 14 and the transparent layer 15 directly affects the accuracy of the displayed color, so in order to achieve an excellent display effect, the display unit High manufacturing precision is required. In order to ensure the manufacturing precision of the display unit, it is necessary to strictly control the product quality and reduce the defective rate, which will lead to an increase in the cost of the manufacturing process
