Embodiment 1

[0022] Prepare a roll of light-enhancing film with spot damage, place the light-enhancing film on the die-cutting machine, and draw ten lines of spot damage on the light-enhancing film through IQC; use a film ruler or digital display vernier caliper to accurately measure the spot damage and the difference between the spot damage The distance between them is marked on the light-enhancing film material with a paintbrush. In the present embodiment, the spot damage distance is 518mm;

[0023] When operating on the machine, reconfirm the distance between the point damage and the point damage. There is a centering red line marked in the middle of the die-cutting machine. Insert the enhancement film into the die-cutting machine so that the centering red line on the die-cutting die and the mark come out. The point damage line is aligned, two parallel marking blades are set at the lower end of the knife die, and the point damage line is located between the two marking blades;

Abstract

The invention discloses novel brightness enhancement film regular point damage sheet marked die cutting manufacture method. The method comprises the following steps: preparing a roll of brightness enhancement film with point damages, placing the brightness enhancement film on a die cutting machine, looking for the point damages on the brightness enhancement film by IQC and drawing ten point damage lines; accurately measuring the distance between the point damages by a micro rule or a digital vernier calliper, and marking the distance on the brightness enhancement film material by a brush; arranging two parallel marking blades at the lower end of a cutting die, wherein the point damage lines are located between the two marking blades; setting parameters of an operation template of the die cutting machine by an operator according to the point damage distance, setting a skip distance, and marking with a 40 cutting die; after marking, performing die cutting, and selecting qualified products without cutting marks finally. According to the invention, in the manner of marking the brightness enhancement film with point damages, the brightness enhancement film with marks is removed by normal die cutting and then the qualified products without cutting marks are selected, so that the use efficiency of raw material can be improved greatly, and company benefits can be increased greatly.

Description

technical field [0001] The invention relates to the field of die-cutting processing of a brightness enhancement film, in particular to a new type of brightness enhancement film regular spot damage sheet marking die-cutting process and method. Background technique [0002] With the continuous development of liquid crystal display technology, the application fields of liquid crystal displays, especially color liquid crystal displays, are also constantly expanding. Prism film is the most widely used brightness enhancement product today. (Also known as enhancement film) It is suitable for liquid crystal display modules of various sizes ranging from mobile phone display screens to liquid crystal displays. Prism film is used in almost all LCD backlights. Prism film is a layer of transparent plastic film with a thickness between 50 and 300 microns, and the upper surface of the film is evenly and neatly covered with a layer of prism structure. The prism film is placed between the...
