Mold, light guide plate and processing method thereof, display screen and electronic equipment

Abstract

The invention discloses a mold, a light guide plate, a machining method of the light guide plate, a display screen and electronic equipment. The mold comprises a light guide plate mold cavity and a material flow channel, wherein the light guide plate mold cavity is provided with a first side wall and a second side wall which are intersected, a column structure is arranged in the light guide platemold cavity, the first side wall is provided with a large water port, the second side wall is provided with at least one minimum position portion, a surface which passes through the minimum position portion away from the first side wall by the longest distance and is perpendicular to the second side wall is taken as a reference surface, and a pin-point gate is arranged on the second side wall, andis located on the side, far away from the first side wall, of the reference surface; and the material flow channel is located on the outer side of the light guide plate mold cavity, directly communicates with the pin-point gate, and is configured to meet the requirements that a molten material flowing out from the pin-point gate is guided to flow out from the large water port and the molten material flowing through the portion between the column structure and the second side wall flows toward the center of the light guide plate mold cavity. According to the mold, the service life of the lightguide plate can be prolonged.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a mold, a light guide plate and a processing method thereof, a display screen and electronic equipment. Background technique [0002] With the development of electronic equipment, users have higher and higher requirements on the appearance of the electronic equipment. It has become a development trend to mount functional devices, such as cameras, on display screens of electronic devices. However, in order to realize the function of carrying functional devices on the display screen, it is usually necessary to open holes on the light guide plate of the display screen. Since the functional device holes are close to the outer periphery of the light guide plate, the strength at this position is low, which affects the reliability of the whole machine. During the test, due to the heat and cold impact of the light guide plate, cracks will occur at the welding line of the l...

Problems solved by technology

However, in order to realize the function of carrying functional devices on the display screen, it is usually necessary to open holes on the light guide plate of the display screen. Since the functional device holes are close to the outer periphery of the light guide plate, the strength at this position is low, which affects the reliability of the whole machine. During the test, due to the heat and cold impact of the light guide plate, it will crack at the welding line of the light guide plate (the hole position will pull the iron frame of the backlight when the heat expands and contracts), and the life of the light guide plate will be reduced.
