Abstract
The invention discloses a front light source module, a display device, a display method and a manufacturing method of the display device in order to solve the problems that when a dark state is displayed, contrast sharply drops, color gamut is reduced and the display effect is poor due to the fact that light emits from both sides of a front light source module in the prior art. The embodiment of the invention provides the front light source module, and the front light source module includes a waveguide plate, light source structures, grating structures and light-shielding structures, wherein the light source structures are located on at least one side face of the waveguide plate and used for providing total reflection light for the waveguide plate; the grating structures are located on thelight-emitting surface of the waveguide plate and used for extracting the total reflection light in the waveguide plate; and the light-shielding structures are located at the positions, deviating from the light-emitting surface, of the waveguide plate and correspond to the grating structures one by one, and in the direction perpendicular to the light-emitting surface of the waveguide plate, orthographic projection of the light-shielding structures at least partially overlaps with orthographic projection of the grating structures.
Description
technical field [0001] The invention relates to the technical field of semiconductors, in particular to a front light source module, a display device, a display method and a manufacturing method. Background technique [0002] Flat panel display devices such as liquid crystal displays (Liquid Crystal Display, LCD) have many advantages such as thinness, energy saving, and no radiation, so they are widely used in high-definition digital televisions, computers, personal digital assistants (PDAs), mobile phones, digital cameras and other electronic devices. in the device. [0003] Reflective liquid crystal display devices in liquid crystal display devices are classified into passive display devices and active display devices. Both sides of the front light source module of the reflective display device emit light, resulting in a sharp drop in contrast when the display is in a dark state (that is, in a weak ambient light or in a dark room environment), resulting in a reduced color...
