however, in the prior art, almost all panels need to display Chinese and English simultaneously in the actual use process, and since Chinese memory occupies more space than English, the content refresh rate may be slow and repeated operations may be caused under the condition of Chinese and English mixed display.

SUMMERY OF THE UTILITY MODEL

Therefore, to foretell problem, the utility model provides an improve type liquid crystal module, it solves prior art still to have all almost the panels to all need show chinese and english simultaneously in the in-service use process, because chinese memory occupies to be big than english, consequently probably leads to the content to refresh the technical problem that the speed leads to repetitive operation slower under the mixed demonstration of chinese and english condition.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides an improved generation liquid crystal module, includes control circuit, power supply circuit, MCU chip, LCD drive circuit, LCD data buffer circuit, memory module, the mixed display treater of chinese and english, control circuit's front end is equipped with the control signal receiver who is used for received signal, control signal receiver's output is connected to control circuit's input, control circuit's output is connected to the control input of MCU chip, power supply circuit is connected with the power end electricity of MCU chip, the control output of MCU chip is connected to LCD drive circuit, another output of LCD drive circuit still is connected with LCD data buffer circuit, LCD data buffer circuit's output and the mixed display treater of chinese and english are connected, the output of the mixed display treater of chinese and english is connected to another input of LCD drive circuit.

Furthermore, the control signal receiver is connected with an infrared receiver or a Bluetooth or USB wired receiver.

Further, the output end of the LCD driving circuit is connected with the LCD panel at the rear end.

Furthermore, the other output end of the LCD data buffer circuit is connected to a storage module, and the storage module is connected with the MCU chip in a bidirectional mode.

Furthermore, the Chinese and English mixed display processor is a chip with the same structure and different functions as the MCU chip.

By adopting the technical scheme, the beneficial effects of the utility model are that: this improved generation liquid crystal module sets up LCD data buffer circuit, memory module, chinese-english mixed display treater has improved prior art still and has had almost all panels to show chinese-english simultaneously in the in-service use, because chinese memory occupies more than english, consequently probably lead to the content refresh rate to lead to the repetitive operation slower under the mixed demonstration of chinese-english, adopt the mixed text of full-time chinese-english mixed display treater processing multilingual, set up LCD data buffer circuit, memory module, effectual improvement treatment effeciency, the normal demonstration and the refresh of equipment have been guaranteed, avoid the problem of the maloperation that the card pause leads to.
