Embodiment Construction

[0011] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0012] As mentioned above, the basic idea of ​​the present invention is: connect the computer VGA output interface with the optical display rear projection TV VGA input interface, and load the graphic mode after the computer is turned on, so that the VGA input end of the optical display rear projection TV displays a predetermined 's graphics. The operation of the microprocessor of the optical display rear projection TV is controlled through the OSD menu of the optical display rear projection TV, and the predetermined pictures and texts of the VGA input terminal are read and stored in the EPROM. When the optical display rear projection TV is turned on, it reads the graphic files stored in the EPROM and restores it to R, G, B data, and inputs it to the display drive circuit to display the graphic text on the TV screen, and reali...

Abstract

The invention discloses a kind of television which can change the start image online and the method, the user can display any image and text on the start image according to the demands. The computer VGA output interface is connected with the VGA input interface of the lightshow back projecting television, when the computer is powered on, it loads the image and text mode, makes the VGA input end of the lightshow and back projecting television display the preset image and text. The microprocessor of the lightshow back projecting television is controlled to act through the OSD menu of the television, reads the preset image and text on the VGA inputting end, and stores them in the EPROM. The television read the image and text file in the EPROM, and reduces the into R, G, and B data, they are inputted into the display driving circuit, the image and text can be displayed on the television screen, realizes the online change of the start image.

Description

【Technical field】: [0001] The present invention relates to a television set and a method thereof that can change the start-up display screen online, in particular to the light display rear-projection television. 【Background technique】: [0002] At present, the method for setting the start-up screen of a rear-projection TV is to pre-solidify the graphics and texts to be displayed in the memory, and after the power-on, the CPU reads the graphics and text data in the memory, traces the matrix of the display pixels, and displays the graphics and texts. On the TV screen, this kind of light display rear projection TV has great shortcomings. Once the software of the light display rear projection TV is written into the memory, the displayed picture cannot be changed. If the user of the light-display rear-projection TV wants to display the desired graphics and text on the boot screen, he must contact the manufacturer and re-write the TV software. [Content of the invention]: [000...
