Problems solved by technology

And ODC IC can't receive these two signals at all
When updating the program of the flash memory chip connected to the ODC, the program cannot be updated directly through the serial interface communication method, and the flash memory chip to be upgraded must be replaced by the flash memory chip that has been written with the new program. A lot of inconvenience has come; moreover, replacing a new flash storage chip also causes a waste of parts and increases the cost

Embodiment Construction

[0031] A liquid crystal display with optional mode for program upgrade according to the present invention includes a user selection menu 1 , a single chip microcomputer 2 , a switch control chip 3 , a response time acceleration engine chip 4 , a zoom chip 5 and a signal input unit 6 . The user selects menu 1 to select the program upgrade method. One end of the single-chip microcomputer 2 is connected to the user selection menu 1, and the other end is connected to the switch control chip 3. The single-chip microcomputer 2 transmits different level signals to the switch control chip 3 according to the program upgrade method selected by the user, and the user selects and responds to the time acceleration engine chip. When the program upgrade mode connected with 4 is selected, the level signal is a high level signal "1"; when the program upgrade mode connected with the scaling chip 5 is selected, the level signal is a low level signal "0". The switch control chip 3 receives the pr...

Description

1. Technical field [0001] The invention relates to a method for upgrading a liquid crystal display, in particular to a method for upgrading a program in a selectable mode of the liquid crystal display. 2. Background technology [0002] With the rapid development of science and technology, computers have become an indispensable part of people's daily life. The display is an important part of the computer, it displays the information people need. The original CRT monitors are bulky and heavy, and will cause damage to the user's eyes after long-term use, so the use of CRT monitors is limited. The liquid crystal display is not only small in size and light in weight, but also has low power consumption and low high-frequency generation, and will not cause damage to users' eyes after long-term use, so its demand is gradually increasing. In particular, display devices are gradually becoming larger, and liquid crystal displays, which are excellent in volume and weight, are graduall...
