Description

A directional backlight naked-eye 3D parallel optical fiber array manufacturing device

technical field

The invention relates to the technical field of directional backlight display, in particular to a device for manufacturing a directional backlight naked-eye 3D parallel optical fiber array.

Background technique

With the development of display technology, some display devices such as display screens have become more mature. At present, the commonly used backlights include LED backlights, but LEDs have certain limitations as directional backlights for naked-eye 3D backlights. The design structure of the directional backlight 3D technology is based on the improvement of the lens structure, and the naked-eye 3D display effect is achieved through the change of the backlight source and the structural adjustment between the display layers, that is, the directional time-division backlight naked-eye 3D. The directional time-division backlight naked-eye 3D technology can keep the original resolution of the LCD panel unchanged. The traditional method can achieve very low crosstalk at a specific viewpoint, so that naked-eye viewing will not cause dizziness and low resolution. The optical fiber backlight is used for spatial periodic display, which is performed synchronously with the 3D video source, thereby reducing crosstalk, and can switch between 2D and 3D, and can also be viewed by multiple viewpoints. The light backlight backlight module is characterized by the uniform light emission of the optical fiber and the control of the precision control and error detection of the parallel optical fiber array. The precise control of the directional backlight of the parallel fiber array can enable the fiber light source to perform directional light splitting more accurately, and at the same time separate the left and right images of the video source to achieve naked-eye 3D high-quality visual effects.

The existing directional backlight 3D display screen generally utilizes a backlight composed of two groups of LEDs and a light guide plate with a symmetrical structure combined with a 3D diaphragm with a special structure to form a directional backlight. Two groups of LEDs are placed on the left and right sides of the display screen, and a light guide plate is placed between the LEDs. The back of the light guide plate is a triangular columnar grating with a symmetrical structure, and a 3D film is placed in front of the front of the light guide plate. The back of the 3D film is triangular. Cylindrical grating, the front of the 3D diaphragm is a cylindrical grating. The light emitted by the LED is reflected by the triangular columnar grating of the light guide plate to the triangular columnar grating of the 3D film, and then concentrated by the cylindrical grating of the 3D film, projecting the right eye image on the LCD screen to the right eye of the observer. To achieve the purpose of directional backlight; similarly, the light emitted by the LED is reflected by the triangular columnar grating of the light guide plate to the triangular columnar grating of the 3D diaphragm, and then concentrated by the cylindrical grating of the 3D diaphragm to project the left eye image on the LCD screen to the observer's left eye. It can be seen that the directional backlight of the above-mentioned prior art requires a light guide plate with a special structure and a 3D diaphragm with a special structure. The reflection surface and the refraction surface through which the light passes require high processing precision and complex structure, and the output light energy uniformity of the light guide plate It is difficult to control, so it is difficult to form a mature product.

All the side-emitting POFs are arranged in parallel in a straight line and pasted on the black backboard. Numbering is carried out sequentially, the numbering sequence is ①②③①②③…, side-emitting POFs with the same number are 1 group, and are divided into 3 groups in total. All side-emitting POFs with the same number are merged into the side-emitting POF at the incident section of the fiber bundle through the corresponding fiber bundle transition section There are three numbered fiber bundles ①②③ for the same numbered fiber bundles. Each numbered fiber bundle is coupled with the same numbered light-emitting diode (LED). By controlling the LED drive pulse, the side-emitting POF is time-sharingly lit. The POF parallel optical fiber array is a key component of the directional backlight of the naked-eye 3D display, and its manufacturing accuracy directly affects the performance index of the multi-viewpoint anti-vertigo naked-eye 3D display. A feasible error detection device can obtain reliable and effective data parameters.

The existing optical fiber array preparation is to establish a mathematical model of the speed difference between the fiber supply wheel and the fiber winding wheel, and through simulation, it is obtained that the rotation speed of the line supply wheel must be changed to ensure the basic range of tension when changing the fiber layer winding, and the use of dance Wheel micro-control equipment realizes small-scale control of tension fluctuations; and then uses optical fiber winding detection equipment to detect the performance of optical fiber cable in real time; and determines the appropriate lag angle to achieve high-precision cable arrangement; finally, the motor control method of one slave and two masters is used to realize Automatic winding of optical fiber winding equipment.

The present invention adopts side-emitting plastic optical fiber (POF) parallel optical fiber array as a manufacturing device for the directional backlight source of the multi-viewpoint anti-vertigo naked-eye 3D display screen, replacing the traditional light guide plate and liquid crystal switch plate, so as to provide a simple and reliable structure and low manufacturing cost.
