A paramyxovirus vaccine strain for novel coronavirus pneumonia and a construction method thereof are provided. The method includes performing a recombination of N and F genes of Newcastle disease virus type VII of Paramyxoviridae with P, M, H, L genes of Canine distemper virus of Paramyxoviridae to obtain a recombinant virus, inserting S1 gene of the novel coronavirus between the P and M genes of the recombinant virus to obtain a recombinant vector. The vaccine strain constructed can stably and efficiently express the novel coronavirus S1 protein, and induce the body to produce antibodies; and the recombined virus vaccine strain can stimulate the human body to produce mucosal immunity, and the prepared vaccine can be vaccinated through a nasal spray. Moreover, the vaccine strain can be tested in poultry and dogs, saving time, reducing costs, and being more conducive to actual production due to large output.

Paramyxovirus vaccine strain for novel coronavirus pneumonia and construction method thereof

The disclosure discloses a method and device for adjusting grayscale brightness and a 3D display device. In the present disclosure, an initial gray level and a target gray level are determined, and it is determined whether the target gray level is too low or too high, so that it is determined whether over-voltage driving can be applicable, and in the case that it is not appropriate to adjust grayscale brightness through over-voltage driving, a backlight brightness adjustment table is searched, and backlight brightness is adjusted up or down using a found adjustment parameter to thereby adjust the grayscale brightness so as to reduce crosstalk in liquid crystal display.

Method and device for adjusting grayscale brightness and 3D display device

The invention discloses a liquid crystal driving method and apparatus for black frame insertion of an image, and a liquid crystal display device. The method includes, in a black frame insertion period after the frame period ends, sending, by a timing controller, a row of black image data to a register of a source driver; and in the black frame insertion period, maintaining, by the register, the row of black image data being output until the black frame insertion period ends, so as to enable the row of black image data to refresh each row of liquid crystal cells. Accordingly, the complexity of driving processes and the data calculations in the black frame insertion are greatly reduced.

Liquid crystal driving method and apparatus for black frame insertion of image, and liquid crystal display device

A method of processing a display signal includes: obtaining the average of grayscales of at least one display zone in a previous frame of image and a current frame of image respectively; comparing in magnitude the average of grayscales of at least one display zone in the current frame of image with the average of grayscales of the corresponding display zone in the previous frame of image; and outputting a backlight control value to increase or reduce the brightness of an illuminating element corresponding to the display zone when the average of grayscales of the at least one display zone in the current frame of image is larger or smaller than the average of grayscales of the corresponding display zone in the previous frame of image.

Method and apparatus for controlling a backlight brightness according to average grayscales

The present application provides an image display method and device. A frame of 3D image including a left eye image and a right eye image is received, two fields of compensation images are inserted between the left eye image display and the right eye image display, so that the superposed effect of displaying four fields of images of the frame of 3D image is the left eye image or the right eye image, to achieve a 2D image, furthermore, the left spectacle lens of the 3D glasses is opened when the left eye image is displayed, the right spectacle lens of the 3D glasses is opened when the right eye image is displayed, and both the left spectacle lens and the right spectacle lens are closed when the compensation images are displayed, to achieve the 3D image display.

Three dimensional image display method
