- the first substrate or the second substrate in the display panel of the display device constitutes the transparent light guide plate, that is, the transparent light guide plate is integrated on the first substrate or the second substrate of the display panel, and is integrated by the transparent light guide plate.
- the display device mainly includes: a first substrate and a second substrate disposed opposite to each other, and a liquid crystal molecular layer between the first substrate and the second substrate, the first substrate facing one side of the liquid crystal molecular layer a color film layer is formed, an array structure region is formed on one side of the second substrate facing the liquid crystal molecular layer, and a surface of the second substrate facing away from the liquid crystal molecular layer (the side facing away from the light emitting surface) is formed with nanoparticles to form a light guiding layer, and the light guiding layer is formed.
- a side of the layer facing away from the liquid crystal molecular layer is formed with a reflecting plate, and one side of the second substrate is attached with a light source, and the light source is generally placed at an angle to the vertical plane (tilted).
- the light source is obliquely disposed to a side of the second substrate (transparent light guide plate) facing away from the light exit surface thereof.
- the display device in the above structure integrates the transparent light guide plate with the second substrate (the glass substrate replaces the original second substrate and the transparent light guide plate, and the thickness of the original second substrate and the transparent light guide plate becomes a glass substrate thickness of). That is, the second substrate has the function of a light guide plate.
- the light source is closer to the array structure region of the display device.
- the display device may adopt the structure described in any one of the above structures 1 to 5.
- the structure of the transparent light guide plate mentioned in the structure 1 to the structure is the structure of the second substrate in the display device of the above structure, so that the influence of the light source on the array structure region can be effectively reduced, and the display effect of the display device can be improved.
- the display device may be any product or component having a display function such as a liquid crystal panel, an electronic paper, a mobile phone, a watch, a tablet, a television, a display, a notebook computer, a digital photo frame, a navigator, and the like.
- a display function such as a liquid crystal panel, an electronic paper, a mobile phone, a watch, a tablet, a television, a display, a notebook computer, a digital photo frame, a navigator, and the like.
- the patterning process may include only a photolithography process, or may include a photolithography process and an etching step, and may also include other processes for forming a predetermined pattern, such as printing, inkjet, and the like.
- the photolithography process refers to a process of forming a pattern by using a photoresist, a mask, an exposure machine, or the like including a process of film formation, exposure, and development.
- the corresponding patterning process can be selected in accordance with the structure formed in the embodiments of the present invention.
