38 results about "Display lag" patented technology

Display lag is a phenomenon associated with some types of liquid crystal displays (LCDs) like smartphones and computers, and nearly all types of high-definition televisions (HDTVs). It refers to latency, or lag measured by the difference between the time there is a signal input, and the time it takes the input to display on the screen. This lag time has been measured as high as 68 ms, or the equivalent of 3-4 frames on a 60 Hz display. Display lag is not to be confused with pixel response time. Currently the majority of manufacturers do not include any specification or information about display latency on the screens they produce.

Projection screen annotation method and system

The invention discloses a projection screen annotation method and system. The method comprises the following steps of: dividing a first terminal into a plurality of canvas layers which comprise a first canvas layer and a second canvas layer; obtaining coordinate information in real time, drawing a first annotation handwriting on the first canvas layer according to the coordinate information, directly displaying the first annotation handwriting, and simultaneously transmitting the coordinate information to a second terminal through a network; converting the coordinate information to obtain coordinate conversion information, and drawing a second annotation handwriting in the second terminal according to the coordinate conversion information; obtaining and storing a screenshot image of the current screen on the second terminal, transmitting the screenshot image to the first terminal by the network, and displaying the screenshot image on the second canvas layer; and erasing the first annotation handwriting drawn on the first canvas layer, and displaying the screenshot image of the first terminal. According to the method and system disclosed by the invention, the problem of inconvenient operation caused by annotation handwriting display lag due to the influences of wireless environment and hardware resource is solved, so that the users cannot feel the bluntness of the writing and then the user experience is enhanced.

Application of ketamine to treatment of major depressive disorder

The invention provides an application of a combined drug composition of ketamine or S-(+)-ketamine or a pharmaceutically acceptable salt of ketamine or S-(+)-ketamine, and escitalopram or a pharmaceutically acceptable salt of escitalopram, to the preparation of drugs for treating major depressive disorder. The major depressive disorder can be major depressive disorder breaking out for the first time, major depressive disorder breaking out again or refractory depression. The invention furthermore provides an application of ketamine or S-(+)-ketamine or the pharmaceutically acceptable salt of ketamine or S-(+)-ketamine to the preparation of the drugs for treating the major depressive disorder, and a drug preparation containing ketamine or S-(+)-ketamine or the pharmaceutically acceptable salt of ketamine or S-(+)-ketamine, and escitalopram or the pharmaceutically acceptable salt of escitalopram. Ketamine and conventional antidepressants are used together; and a proper amount of ketamine is intravenously injected once at first day of start of treatment, so that the anti-depression effect of oral antidepressants can be effectively improved, the effect display lag period is remarkably shortened, and suicidal actions of patients can be remarkably reduced.

Screen sharing display method, device and equipment and storage medium

PendingCN112714273AImplement shared display methodSolve the problem of large data trafficTelevision conference systemsTwo-way working systemsDisplay lagComputer graphics (images)
The embodiment of the invention provides a screen sharing display method and device, equipment and a storage medium. The method comprises the steps: acquiring two adjacent frames of images of first terminal equipment; determining image change information according to the two adjacent frames of images, wherein the image change information represents the change degree of the latter frame of image relative to the former frame of image in the two adjacent frames of images; if it is determined that the change degree represented by the image change information is greater than or equal to a first preset degree, compressing the next frame of image to obtain compressed image data; and sending the compressed image data to the second terminal device to be displayed. Due to the fact that the first terminal device compresses the image according to the change degree of the image, the image data corresponding to the screen image is compressed in the screen sharing process if the change degree of the image is large, and under the condition that the effective data transmission is not influenced, the transmission data volume is reduced, so the problem of large data flow in the screen sharing display process is solved, and the display lag is reduced.

A Video Display System with Enhanced Display Resolution

The invention discloses a video display system capable of improving display resolution. The video display system comprises a driving module capable of supporting multiple resolutions and multiple video formats, a data storage module for caching video images and a display module for displaying the images, wherein the driving module decomposes each frame of received original video image into four video images of which the resolution is lower than that of the original video image, the pixel resolution of the display module and the resolution of the decomposed video image are kept consistent, andfour decomposed video images are displayed on a display screen in a dynamic combination mode according to different sub-pixel units within one frame of time of an original video image. According to the invention, higher visual resolution can be obtained under the condition that the power consumption and the size of the display screen are not obviously increased, the purpose of displaying images with higher resolution by using a screen with lower resolution can be realized, the actual display effect superior to that of a screen with lower resolution is obtained, and the method is particularly suitable for application scenarios with higher requirements on display area and power consumption.
