Abstract: An apparatus and a method for controlling a screen are disclosed herein, the apparatus includes an object detection module and an adjusting device. The object detection module can detect a position of at least one object. A position analyzer recognizes the position of the object and the adjusting device can set the screen to a predetermined position according to the result recognized by the position analyzer.

Abstract: A brightness adjustment system includes a camera, a computer, and a liquid crystal display. The liquid crystal display includes a signal processor, a backlight control circuit and a backlight unit. The camera captures environmental images and sends the environmental image to the computer. The computer analyzes the environmental image to obtain a environmental brightness and sends a control signal to the signal processor according to the environmental brightness. The signal processor receives the control signal and sends an adjusting signal to the backlight unit according to the control signal. The backlight control circuit adjusts a brightness of the backlight unit according to the adjusting signal. A method of automatically adjusting brightness of a liquid crystal display is also provided.

Abstract: An exemplary on-screen display (OSD) system (3) includes a display device (5) and a computer (4) connected to the display device. The display device includes a micro processing unit (MPU) (532) configured for providing a plurality of instruction signals according to external instructions. The computer includes a memory (41) and a central processing unit (CPU) (42). The memory includes an external OSD unit (412) configured for generating an external OSD menu. The external OSD menu is colorful and dynamic. The CPU is configured for identifying the instruction signals from the MPU and providing control signals corresponding to the instruction signals. The external OSD unit is capable of setting and assigning data to generate the external OSD menu on receiving the control signals from the CPU, whereupon the external OSD menu is displayed on the display device.

Abstract: An exemplary system for inspecting pictures of a liquid crystal display (LCD) (20) is provided. The system is configured in a host computer (10) that stores standard parameters of pictures for display by the LCD. The system includes: a setting module (13) configuring for setting one or more parameters of the pictures and a video card, and for generating corresponding signals according to the set parameters, the set parameters being for one or more function inspections of the LCD; a transmitting module (15) configuring for transmitting the signals to the LCD so that the LCD can process the signals and display corresponding pictures; a determining module (17) configuring for comparing actual parameters of the pictures actually displayed on the LCD with the standard parameters, and for determining whether the set parameters of the pictures and the video card are satisfactory according to a result of the comparison.

Abstract: A system and method for automatically upgrading the firmware of a display without user interaction, wherein a new version of firmware is downloaded and stored at a host computer. The host computer monitors all communications between the host computer and an external source to determine when new or updated firmware has been uploaded. If the host computer includes a graphic card, the display is checked to determine whether it is active. If the display is active, communication over a communication cable located between the host computer and display is established, and the new version of firmware is uploaded to memory located in the display. The host computer forwards the firmware over the communication cable as at least one signal component, such as data and clock signals, which is transmitted from a graphic card located in the host computer to a graphic processor located in the display.
