The invention relates to a vision testing and training system based on virtual reality. The vision testing and training system comprises a head-wearing device, an image processing device in communication connection with the head-wearing device, an intelligent control device in communication connection with the head-wearing device and the image processing device, as well as a dizziness-preventing device and a remote terminal device which are in communication connection with the intelligent control device, wherein the head-wearing device comprises an image display device, an audio play device and a motion sensing device; the dizziness-preventing device is used for receiving the control of the intelligent control device so that the conversion angle of a vision testing image or a vision care image received by a user and the head position and angle shifting motion state of a user are synchronous, thus no dizzy feeling is generated during testing and health care, and therefore, the real sense of immediacy and sense of reality are achieved.

The embodiment of the invention relates to a method, a device and a terminal for testing vision. The method comprises the following steps: acquiring position information of a tested person relative to a display screen for displaying optotypes; determining a display method of the optotypes based on the position information; displaying the optotypes on the display screen according to the display method; receiving a judgment result for the optotypes input by the tested person; and determining a vision testing result of the tested person based on the judgment result. With the adoption of the method, the device and the terminal for testing vision, a user can conveniently test the vision condition of the user without a special device, the special environment, a professional or the help of others, therefore, the vision testing process is simplified, and the intelligence level of vision testing is improved; and meanwhile, the functions of the terminal device are also enhanced.

A system and associated methods for animated image vision testing is disclosed. In at least one embodiment, a vision test includes at least one animated dynamic optotype image for measuring the visual acuity of a subject. The animated image vision test takes advantage of the ability of the human eyes to detect both distance and motion. Moving images, such as rotating segmented circles, let the eyes detect motion as to the size, distance, and rotation direction of that moving image. That motion detection is much more precise than the interpretation of multiple static letters or static images. Using rotating images for vision testing rather than static images creates an acuity test more accurate than current tests, a test that is faster to use, and a test that does not require the ability to read.

The invention discloses an array substrate, a driving method thereof and a display panel. The array substrate at least comprises sub pixels distributed in an array mode, a plurality of first light-emitting control signal wire groups and a plurality of second light-emitting control signal wire groups, each first light-emitting control signal wire group comprises at least one first light-emitting control signal wire, and each second light-emitting control signal wire group comprises at least one second light-emitting control signal wire; in the sub pixels in each line, the colors of the sub pixels connected with the first light-emitting control signal wires are the same. The driving method includes the steps that first signals are applied to the first light-emitting control signal wire groups one group by one group, and meanwhile second signals are applied to the other light-emitting control signal wire groups so that the sub pixels connected with the first light-emitting control signal wire groups can be displayed, and the sub pixels connected with the other light-emitting control signal wire groups can not be displayer. By means of the driving method, testing of the display performance of the array substrate in the vision testing phase can be achieved.
