Abstract
The invention discloses a display device and a display method. The display device includes a light source, a light guide plate, and a liquid crystal panel; the liquid crystal panel includes a first substrate and a second substrate which are oppositely arranged, and a liquid crystal layer is arranged between the first substrate and the second substrate; light emitting graphs are arranged on the light guide plate; incident light of the light source forms at least three colors of monochromatic light beams through the light emitting graphs of the light guide plate; the light source is lighten at different time slots, the at least three colors of monochromatic light beams are irradiated to identical sub pixel electrodes of the first substrate within each frame time at different time slots to form reflective light beams; and the reflective light beams are modulated by the liquid crystal layer and are displayed. In the embodiment of the invention, the light source is lightened at different time slots, the at least three colors of monochromatic light beams are irradiated to identical sub pixel electrodes of the first substrate within each frame time at different time slots, i.e., at least three colors of monochromatic light beams can be displayed at each sub pixel point position, and then the PPI of the display device can be improved.
Description
technical field [0001] The present application relates to but not limited to the field of display technology, especially a display device and a display method. Background technique [0002] With the development and upgrading of display technologies, various types of displays appear, including, for example, liquid crystal displays (Liquid Crystal Display, LCD for short). In a display, an optical processing to form a display device with various colors is an important part thereof. [0003] LCD displays generally include reflective LCD displays and transmissive LCD displays. Such as figure 1 As shown, it is a schematic structural diagram of a display device in the prior art. The display device is a reflective display device, and its basic structure generally includes: a first substrate and a second substrate for the box, and a polarizer (Polarizer, referred to as : POL) and light guide panel (Light GuidePanel, referred to as: LGP). Wherein, the first substrate may be a thin...
