Embodiments of the invention disclose a display device, electronic equipment and a manufacturing method of the display device. The display device comprises a display panel, a polarizer, a backlight module and shading glue, wherein the display panel is provided with a light-transmitting area and a shading area, and the shading area is arranged around the periphery of the light-transmitting area; the polarizer is arranged on the display panel, a first through hole is formed in the polarizer, and the first through hole is arranged to correspond to the light-transmitting area; the backlight moduleis arranged on the polarizer, a second through hole is formed in the backlight module, and the second through hole is arranged to correspond to the light-transmitting area; and the shading glue is arranged on the periphery of the hole wall of the second through hole and extends to the periphery of the hole wall of the first through hole. According to the scheme, the glue dispensing frequency during assembly of the display device is reduced and the coating precision of the periphery of the light-transmitting area is improved.

The purpose of the present invention is to provide a lens unit which can create an effective light shield despite the simple process by which the lens unit is produced. A non-transmissive filler (BD) is filled and solidified in the gap between the outer periphery of a light shielding member (SH1) and the outer peripheries of a first lens (L1) and a second lens (L2).

There is provided a quality evaluation device capable of evaluating the quality of fruits-vegetables with a high accuracy. The transmitting light from an object (M) to be measured is received by a light reception sensor of charge accumulation type. Charge is accumulated in the light reception sensor from the accumulation start timing until the time set for accumulation has elapsed. After this, anelectric charge accumulation discharge processing for discharging the electric charge accumulated in the light reception sensor until the time set for discharge has elapsed is repeatedly performed. When the object (M) reaches the measurement position, the charge accumulated is discharged. After this, a measurement charge accumulation processing is performed for accumulating charge used as light reception information for quality evaluation. Furthermore, the quality evaluation device includes: a light reception section (2) for receiving near-infrared light projected from a projection section (1)to the object to be measured by performing spectral analysis; and a calculation section for calculating a quality value of the fruit-vegetable in accordance with the received light information from the light reception section (2) and a measurement equation. This calculation section is configured so as to perform wavelength calibration in accordance with the received light information obtained when a reference body for wavelength calibration is measured. The measurement equation is created with a smaller resolution than the maximum resolution of the received light information decided in accordance with the number of unit light reception sections. The wavelength calibration performed by using the received light information is performed with a smaller resolution than the resolution requiredfor creating the measurement equation.

An all-round adjustable mobile phone camera shading device, including a box structure with front and rear windows composed of bottom, top and left and right sides; the bottom is composed of a U-shaped clamping plate main body, including the top surface, bottom surface and clamping gap , and the top surface is connected with an L-shaped stop plate extending forward, and the top is also composed of a U-shaped clamping plate main body; the left and right sides are composed of a U-shaped plate main body, and the U-shaped plate main body includes forming the side of the device. The side plates are connected to the upper and lower ends of the side plates and the bottom plate is formed. The top plate is movably inserted in the clamping gap of the top U-shaped clamping plate, and the bottom plate is movably inserted in the clamping gap of the bottom U-shaped clamping plate. When using a mobile phone to take pictures, put the mobile phone into the L-shaped stop plate, adjust the height of the device, and then slide the U-shaped clamping plate at the bottom to clamp and position the mobile phone, and then the camera operation can be carried out. Effective shading is carried out, and the user can watch the mobile phone screen through the window of the device to improve the quality of the photo taken.

An adjustable shading device used for taking photographs with a mobile phone comprises a box body structure which is composed of a base, a top and a left lateral part and a right lateral part and is provided with a front window and a rear window, wherein the base of the device is composed of a U-shaped clamping board body and comprises a top surface, a bottom surface and a clamping gap, the top surface is connected with an L-shaped baffle extending forward, the top of the device is also composed of a U-shaped clamping board body, the left lateral part of the device is composed of a U-shaped board body, and the right lateral part of the device is composed of a U-shaped board body. Each U-shaped board body comprises lateral boards which form the lateral parts of the device, a top board connected with the upper ends of the lateral boards, and a base board connected with the lower ends of the lateral boards, wherein the top board is movably inserted in a clamping gap of the U-shaped clamping board of the top of the device, and the base board is movably inserted in the clamping gap of the U-shaped clamping board of the base of the device. When the mobile phone is used for taking photographs, the mobile phone is placed in the L-shaped baffle, the height of the device is adjusted, and then the mobile phone is clamped and positioned through sliding of the U-shaped clamping board of the base of the device for photograph taking. Due to the fact that the screen of the mobile phone is effectively shaded by the device, a user is enabled to observe the screen of the mobile phone through the windows of the device, and then quality of photographs taken is improved.

The present invention is preparation process of theasaponis sterilant for preventing and controlling rat plague. The theasaponis sterilant is prepared with tea seed cake as main material, and through extracting with water solution of hydrophilic solvent at 50-80 deg.c for 1-3 times, merging the extracted liquid and filtering; membrane separating the filtrate to eliminate impurity and concentrating to 10-15 Baume degree (60 deg.c); adding 4 wt% concentration water solution of sodium alginate in the same weight as the concentrate; dropping the mixture into 4 wt% concentration water solution of calcium chloride in the same weight; stilling at 4-10 deg.c for 8-12 hr to cure and shape; sieving grains of diameter 4-6 mm and drying to obtain the theasaponis sterilant. The preparation process is novel, simple, efficient and low in production cost, and the theasaponis sterilant has high efficiency in preventing and controlling rat plague, low toxicity and other advantages.
