In an embodiment, the system includes a direct input device (the “client”) executing a client application (“app”), a secondary device (the “server”) executing a server app, and a network link between the server and the client. The server app transmits to the client app, via the network link, a portion of the content displayed on the server's computer screen. The client app may display this portion. Whenever the user interacts with the client device, the client app transmits those interactions to the server app over the network link. The server app sends an acknowledgement to the client app and provides the received interactions to the spatial input software executing on the server, and the spatial input software consumes the interactions as if the user performed the interactions on the server device itself.

To provide an active matrix display device in which power consumption of a signal line driver circuit can be suppressed, so that power consumption of the entire memory can be suppressed. A plurality of memory circuits which can write data of a video signal input to a pixel in one line period and can hold the data are provided in a signal line driver circuit of a display device. Then, the data held in each memory circuit is input to a pixel of a corresponding line as a video signal. By providing two or more memory circuits in a driver circuit, pieces of data of video signals corresponding to two or more line periods can be concurrently held in the memory circuits.

An electroluminescence display apparatus includes a display panel, including a pixel including a driving element and a light emitting device, and a panel driving circuit supplying the pixel with a first data voltage for a display driving operation and a display scan signal synchronized with the first data voltage in a vertical active period succeeding a first vertical blank period and maintaining the first data voltage in the pixel during a second vertical blank period succeeding the vertical active period, wherein a length of the first vertical blank period is fixed regardless of a variation of a frame frequency, and a length of the second vertical blank period varies based on the variation of the frame frequency.

When rendering a frame, e.g. that is to be used for rendering subsequent frames to be rendered, two versions of the frame are rendered, and sets of information representative of the content of the versions of the frame are compared to determine whether the first and second versions of the frame match or not. When the comparison determines that the two versions of the frame match, the frame is, e.g. used for rendering subsequent frames, but when the comparison determines that the two versions of the frame do not match, an error operation is performed.

When rendering a frame, e.g. that is to be used for rendering subsequent frames to be rendered, two versions of the frame are rendered, wherein the first version of the frame is rendered in its entirety but only a portion of the second version of the frame is rendered. The rendered portion of the second version of the frame is compared to a corresponding rendered portion of the first version of the frame. When the comparison determines that the two portions of the two versions match, the frame is, e.g. used for rendering subsequent frames, but when the comparison determines the two portions of the two versions do not match, an error operation is performed.

The method comprises: generating a point-to-point configuration instruction that comprises n configuration data where n≥2; sending the point-to-point configuration instruction to a first source driver chip through a first signal line, the first source driver chip being any one of a plurality of source driver chips; and receiving a configuration response instruction sent by the first source driver chip according to the point-to-point configuration instruction through the first signal line, the configuration response instruction comprising configuration response data for each of the n configuration data.

A display device that inhibits display deterioration is provided. The display device estimates the amount of deterioration of a pixel included in the display device and corrects a first image signal supplied to the pixel. The display device includes a display panel including a plurality of pixels, a frame memory, and an arithmetic portion. The pixels each include a light-emitting element and a transistor supplying a current to the light-emitting element. The arithmetic portion has a function of performing an arithmetic operation in accordance with a regression model. A forecast error parameter and an output parameter are set in the arithmetic portion. The arithmetic portion updates the forecast error parameter from a first observation signal supplied from the frame memory and a second observation signal supplied from the pixel, in accordance with the regression model, and updates an output parameter by the forecast error parameter in accordance with the regression model. The arithmetic portion corrects the first image signal by the output parameter and generates a second image signal, and the light-emitting element emits light by the second image signal supplied to the transistor included in the pixel.

A display device includes a display panel, a first storage device, a second storage device and a control device. The first storage device is disposed on the display panel and stores a first firmware. The second storage device stores a second firmware. The control device is coupled to the first storage device and the second storage device. The control device reads the first firmware and uses the first firmware to update the second firmware, or receives a third firmware transmitted by a host terminal device and uses the third firmware to update the second firmware. The control device executes the updated second firmware to generate an image signal corresponding to the updated second firmware to the display panel. Therefore, the efficiency of updating the firmware of the display device may be effectively increased, and the convenience of use is increased.
