Abstract
The utility model relates to a light guide plate which is fabricated by installing a metal template made through utilizing a computer-prepared program in the injection molding machine and extruding it after applying an appropriate amount of plastic material on it. The light guide plate is provided with a luminous tube on one end; mesh points of the light guide plate take the shapes of a circle, a triangle and a protruding; the light guide is tabular or wedge-shaped. The utility model has the advantages of high precision, simple process, convenience and applicability to mass production.
Description
Technical field: the utility model relates to a kind of LCD device, particularly relates to a kind of light guide plate in the LCD device.
Technical background: at present,, use light guide plate widely in field of liquid crystal, as guiding scattering of light direction, and the distribution of the site on the light guide plate what, and the depth of site, the brightness that then is used for improving panel.And the processing of light guide plate mesh point, generally be divided into several big classes of printing-type and non-printing-type, it is low that the job operation of printing-type has a cost, make advantages such as simple, but its serviceable life is very short, non-uniform light, can not meet the needs of production, but not the job operation of printing-type adds printing, laser dotting as ejection formation, ejection formation, the principle that methods such as corrosion account for small scale very, are not suitable for producing in batches.
Summary of the invention: the purpose of this utility model will provide a kind of light guide plate exactly, and it can solve the existing defective of above job operation easily and effectively, and has the production in enormous quantities that machining precision height, time are fast, can satisfy product.The purpose of this utility model is to realize like this, described light guide plate mesh point, be to make sensitive film on computers, design has several sites on sensitive film, end closer locations site from luminotron is less, and site centre distance setting is bigger, and far away more from luminotron, the site is big more, and it is also close more to distribute; The sensitive film that is made into is placed on the metal die, through UV-radiation-sensitive, remove photoresist; The metal form of handling well is put into liquor ferri trichloridi carry out etching; The degree of depth of site depends on the etched time on the template, and the general time is long more, and the site on the template is dark more, and the dot etching degree of depth is cleaned through clear water at 0.03-0.1mm, is made into mould.Described light guide plate is arranged to tabular or wedge type shape, be provided with luminotron in light guide plate one side, the dot shape of light guide plate is designed to circle, triangle or convex structure, and the site diameter is between 0.03-0.4mm, and site and site centre distance are between 0.2-0.6mm.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
1. light guide plate, 2. site, 3. luminotron.
Embodiment: the utility model is further described below in conjunction with accompanying drawing.
In the drawings, a kind of light guide plate of the utility model is to make sensitive film on computers, and design has several sites 2 on sensitive film, and site 2 diameters are between 0.03-0.4mm, and site 2 and site 2 centre distance are between 0.2-0.6mm; The sensitive film that is made into is placed on the metal die, through UV-radiation-sensitive, remove photoresist; The metal form of handling well is put into liquor ferri trichloridi carry out etching; The degree of depth of site depends on the etched time on the template, and the general time is long more, and the site 2 on the template is dark more, and site 2 corrosion depths are cleaned through clear water at 0.03-0.1mm, are made into mould.During concrete enforcement, use specific computer program, make sensitive film on computers, sensitization then through in liquor ferri trichloridi template being corroded, is made into template, then the set of molds that processes is contained in injection moulding on the injection machine, can obtains the light guide plate 1 of the design that requires.Described light guide plate 1 can be designed to tabular and wedge type is tabular, is provided with luminotron 3 in a side of light guide plate 1, and is less from an end closer locations site 2 of luminotron 3, site 2 centre distance settings are bigger, and far away more from luminotron 3, site 2 is big more, and it is also close more to distribute; The shape of the site of light guide plate 1 can be designed to circle, triangle or convex structure; Flat board is used for monitor more, and the wedge type plate is used for notebook computer more.
Claims (1)
1. light guide plate, it is characterized in that: light guide plate is tabular or wedge type shape; Side in light guide plate is provided with luminotron; The site of described light guide plate is designed to circle, triangle or convex structure, and the site diameter is 0.03-0.4mm, and site and site centre distance are 0.2-0.6mm, and the site degree of depth is 0.03-0.1mm.
