The purpose of the invention is to provide an image display device which divides single frames into a plurality of fields to perform drive operations, and in which light-source lighting periods of sufficient lengths are ensured. Accordingly, a field-sequential image display device has, provided therein as modes for when data is to be written to pixel units, a normal writing mode in which data is written one row at a time, and a high-speed writing mode in which data having the same values is written a plurality of rows at a time for each column. In blue fields (F(B)), the high-speed writing mode is used to perform data-writing processing. In green fields (F(G)) and red fields (F(R)), the normal writing mode is used to perform data writing processing.

The invention relates to the field of milk powder manufacturing, and in particular to novel milk powder and a manufacturing method thereof. The milk powder comprises the following components in partsby weight: OPO, whey protein powder (containing milk fat globule membranes and cephalin groups), raw milk, yak milk or whole yak milk powder, oligosaccharide, choline, DHA and lutein, and also comprises SN-2, wherein the content of the SN-2 is 60% or above of the weight of total palmitic acid in the milk powder. The OPO structural fat used in the novel milk powder is a new generation OPO, and thenovel milk powder has SN-2 close to the SN-2 level of breast milk, is beneficial to digestion and absorption of babies, and can improve energy intake, reduce constipation, enhance bone density, increase intestinal tract probiotics, reduce crying and improve night sleep. The novel milk powder can also improve cognitive ability, learning ability and memory of infants, can promote growth of probiotics, enhance the immune function of intestinal tracts, improve the stool character of the infants, reduce occurrence of constipation, and promote absorption and utilization of various nutrient substances.

The invention belongs to the technical field of medicines, and particularly relates to selenium-rich eye protection liquid and a preparation method thereof. The eye protection liquid comprises the following components: selenium-rich green tea, cordyceps militaris, propolis, corn stigma, soybeans, field sowthistle herb, purple sweet potatoes, taurine, aloe, water-soluble lutein, and vitamin B1. Themethod comprises the following steps of: filtrate preparation, cordyceps militaris extract preparation, corn stigma extraction, mixed feed liquid preparation, distillate A preparation, finished product preparation and the like. During combination, the selenium-rich green tea, the corn stigma, the soybeans, the field sowthistle herband the purple sweet potatoes are added, have the effects of improving eyesight, relieving eye fatigue, preventing and improving myopia, and can promote the absorption of selenium and other nutrient elements, improve the vision, and quickly relieve eye fatigue. Thesoybeans, the cordyceps militaris and the purple sweet potatoes have high amino acid content, and can promote the taurine part to be integrated with other amino acids, and improve the proliferation, migration and differentiation of cells. The selenium-rich eye protection liquid prepared by the invention also has good antibacterial and anti-inflammatory capability and little irritation to eyes, canbe used for a long time, and has good application environment.

Enhanced visual acuity is provided by one or more exceptionally narrowband absorption dyes having sharp turn-on and cut-off slopes selected to spectrally sculpt light to correct most types of colorblindness, to exaggerate color contrast vision for everyone, and / or to markedly sharpen visual focus beyond normal vision. The dyes are incorporated, for example, in sunglasses, prescription and non-prescription eyewear, window thin films and artificial light sources such as incandescent, fluorescent, and LED lightbulbs to provide improved photopic color vision, improved mesopic dim light color vision, and also sharper scotopic night vision.

The invention relates to a lutein ester soft sweet and a preparation method of the lutein ester soft sweet. The soft sweet comprises 60-90% of sweet material, 0.01-10% of lutein ester micro-capsule or water soluble powder, 0.1-15% of gelling agent, 0.01-5% of sour agent, 0-10% of extract, 0-30% of concentrated juice, 0-0.5% of food flavor and 5-34% of water. The preparation method of the lutein ester soft sweet comprises the following steps of: a. sugaring off; b. gelling; c. mixing sugar liquid with gel liquid or gel peptone; d. adding lutein ester, the extract, the concentrated juice, the flavor and the sour agent into the mixed liquid; and e. preparing a finished product. The lutein ester soft sweet has health care functions of relieving visual fatigue, improving eyesight, preventing age related macular degeneration (AMD), and is good in mouthfeel, not glutinous, chewable and palatable in sour and sweet, thus being a healthy snack food; and the preparation method of the lutein ester soft sweet is simple, easy to operate and suitable for industrial production.

The invention discloses a bloodstain detection method having long wavelength chemiluminescence and fluorescence, and developing functions. The developing liquid of the method is prepared by mixing the water solutions of colourless fluorescein, luminol, hydrogen peroxide, sodium citrate and ethylene diamine tetraacetic acid. The visual sensitivity is enhanced and the visual luminescence time is prolonged by changing the chemiluminescence wavelength, meanwhile the stains with strong fluorescence are formed in the bloodstain area to develop the unsharp bloodstain shape. After the bloodstain search and the preliminary position are carried out by using the luminescence, the yellow-green fluorescence stain corresponding to the bloodstain shape can be observed on the bloodstain position detectedin preliminary by the luminescence method under the natural light, the lamplight or the ultraviolet light, then the following accurate position of the bloodstain by using the fluorescence and the vision is realized to facilitate the recording of the bloodstain shape and the sampling. The method can be popularized and used in the criminal cases investigation.

Provided is a projector capable of preventing double images from being formed due to multiple reflections of a synthetic optical system. In the projector (10), the reflection characteristics of a pair of dichroic films (61), (62) are prevented from repeating or overlapping. Thus, it is possible to prevent the boundary light (BL) of the blue light (LB) or green light (LG) incident on the cross dichroic prism (60) from being reflected twice by the dichroic films (61) and (62). And it becomes the return light which is incident on a liquid crystal panel (51g) etc. That is, it can be prevented that when the two dichroic films (61), (62) have overlapping reflection characteristics, the return light from them is reflected on the liquid crystal panel (51b) etc. A ghost image or the like is formed on the screen (SC).

A progressive multifocal lens comprises a first lens layer, a second lens layer and a third lens layer which are sequentially stacked together, and the first lens layer, the second lens layer and thethird lens layer are made of different materials. The progressive multifocal lens is mainly composed of the first lens layer, the second lens layer and the third lens layer, and the first lens layer,the second lens layer and the third lens layer are made of different materials, so that the first lens layer, the second lens layer and the third lens layer have different refractive indexes, and thevisual sensitivity of the progressive multifocal lens is further improved. In addition, the invention also provides progressive multifocal glasses applying the progressive multifocal lens.
