Problems solved by technology
[0003] Photoluminescence technology can be subdivided into two types. One is used in backlight modules. The commercially available and mass-produced QLEDTV uses a liquid crystal display (LCD) with a quantum dot film (QD film) to produce a high-color The other is the quantum dot color film (QD-CF) structure proposed by Samsung, but there are some technical problems to be solved, such as: because the quantum dot particles will destroy the polarization of light, it is necessary to use more difficult Built-in polarizer (in-cell polarizer) technology, there is no mass production of any product on the market

The invention discloses a display panel and further discloses a device and a method for the display panel, a display device comprising the display panel and a control method of the display device. Thedisplay panel sequentially comprises a first substrate, an electrode layer, a display medium layer, a shielding layer and a second substrate from bottom to top. The display medium layer comprises a retaining wall, a plurality of micro-cup structures which are separated by the retaining wall, the first substrate and the second substrate jointly, and display media, wherein the micro-cup structuresare filled with the display media. The display media are in a liquid state and comprise a plurality of electronegative first quantum dot particles and a plurality of electropositive second quantum dotparticles. In each pixel unit, the electrode layer comprises one or more pixel electrodes located in a shielding area, and different voltages can be applied to the pixel electrodes independently. According to the display panel, the different voltages are applied to the pixel electrodes to control the charged quantum dot particles to move so as to control conversion of colors to achieve the purpose of color display.
Description
technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display panel and a manufacturing method thereof. technical background [0002] The current quantum dot display technology can be divided into two major fields, one is photoluminescence technology, and the other is electroluminescence technology. The electroluminescent structure is similar to the OLED structure, except that the material in the light-emitting layer is replaced by an organic light-emitting material with a quantum dot material. The light-emitting principle is also the same, and the energy emitted by the combination of electrons and holes is used to stimulate light emission. [0003] Photoluminescence technology can be subdivided into two types. One is used in backlight modules. The commercially available and mass-produced QLEDTV uses a liquid crystal display (LCD) with a quantum dot film (QD film) to produce a high-color The other is the quantum dot ...
