Abstract
The utility model provides a liquid crystal visual chart, which aims to solve the problem that the existing dot-matrix liquid crystal visual chart is difficult to realize the definition of smaller sighting targets, and comprises an etching liquid crystal display panel and a dot-matrix liquid crystal display panel which are fixedly connected together. The liquid crystal visual chart adopts a mode of combining the etching liquid crystal display panel and the dot-matrix liquid crystal display panel, so the defect of the dot-matrix liquid crystal display panel is made up, and the minimum sighting target definition with a decimal record V (omitted value) of 1.5 and a sighting target side length of 0.23mm, which is specified by 'near vision test sighting target data', is realized. The liquid crystal visual chart also can utilize the dot-matrix liquid crystal display panel to display a color blindness icon and a new edition of common visual chart. The utility model has the technical scheme which can produce any sighting target which is specified in accordance with the national standard vision chart-standard logarithmic visual acuity chart [GB 11533-1989], and any sighting target of the international standard vision chart.
Description
Technical field
This utility model relates to a kind of visual acuity chart.
Background technology
The existing visual acuity chart that uses is commonly printed matter, comprise the visual acuity chart lamp box, its lamp box panel also is a printed matter, regulation in visual acuity chart national standard---standard logarithmic visual acuity chart [GB 11533-1989] the 4.4th joint " print request ": " the print request sighting target thick black; good colour unanimity; do not show money or valuables one carries unintentionally a little, writing is clear, and lines are very scraped.Sighting target size allowable error ± 5%.White background does not have stain ".The 3.1st the joint " sighting target shape " in the regulation: " adopt three strokes of isometric squares " E " word sighting target, its each stroke or space be the square length of side 1/5th ".4.3.3 joint " distant vision test chart sighting target data " regulation: decimal record V (slightly value) the 2.0 sighting target length of sides are 3.64mm; 4.3.3 joint " near vision test type sighting target data " regulation: decimal record V (slightly value) the 1.5 sighting target length of sides are 0.23mm.From above data, the visual acuity chart of printing can satisfy the regulation of " GB ", but existing dot lcd visual acuity chart just is difficult to reach the regulation of GB for very little sighting target, such as " distant vision test chart sighting target data " decimal record V (slightly value) the 2.0 sighting target length of sides of regulation are 3.64mm, the width of its each stroke has only 0.728mm, space between two strokes also is 0.728mm, because being dot matrix, arranges in liquid crystal, interference each other can take place in so little stroke and space, stand in do not see sighting target outside 5 meters opening in what direction.And decimal record V (slightly value) the 1.5 sighting target length of sides of " near vision test type sighting target data " regulation are 0.23mm, and the liquid crystal visual acuity chart is difficult to realize its definition especially.
The utility model content
The purpose of this utility model is to be difficult to realize the problem of definition for solving present dot lcd visual acuity chart for less sighting target, and then a kind of liquid crystal visual acuity chart is provided.
This utility model comprises: etching (or the plate that a falls) formula LCD panel and a lattice liquid crystal display, etching formula LCD panel and lattice liquid crystal display are fixed together.
The beneficial effects of the utility model: this utility model adopts etching formula LCD panel and the bonded mode of lattice liquid crystal display, has remedied the deficiency that dot lcd shows.
This utility model adopts the etching or the board-like LCD panel that falls, and makes two slits between the liquid crystal cells very little, with the naked eye almost can't see.Decimal record V (slightly value) the 1.5 sighting target length of sides that realized " near vision test type sighting target data " regulations are the definition of the minimum sighting target of 0.23mm.And the lattice liquid crystal display can show bigger sighting target, and etching formula LCD panel and lattice liquid crystal display are made the most of the advantage separately.Can also utilize the lattice liquid crystal display to show achromatopsia detected icon and the general visual acuity chart of new edition (also claiming red-green vision test), increase the measuring ability of visual acuity chart.
The technical solution of the utility model, can make and meet the visual acuity chart national standard---any one sighting target of standard logarithmic visual acuity chart [GB 11533-1989] regulation and any one sighting target of international standard visual acuity chart.
