Abstract

The invention discloses an LCD control circuit, including a logic judgment circuit, a high-level holding circuit, an LCD panel, an oscillation circuit and an execution circuit. The logic judging circuit comprises a first input terminal, a second input terminal and an output terminal. An output terminal of the high-level holding circuit is connected with a first input terminal of the logic judgingcircuit; the output end of the LCD panel is connected with the input end of the high-level holding circuit; An output terminal of the oscillation circuit is connected with a second input terminal of the logic judgment circuit; the input end of the execution circuit is connected with the output end of the logic judgment circuit, and the output end of the execution circuit is connected with the input end of the LCD panel. In addition, the embodiment of the invention also provides a terminal.

Description

technical field [0001] The invention relates to the field of liquid crystal display (LCD) control, in particular to an LCD control circuit and a terminal. Background technique [0002] Currently, there are mainly two types of liquid crystal displays (Liquid Crystal Display, LCD) on the market, one is an organic light-emitting diode (Organic Light-Emitting Diode, OLED) LCD, and the other is a thin film transistor (ThinFilm Transistor, TFT) LCD. OLED LCD is a self-illuminating LCD and does not require an additional backlight, while TFT LCD requires an external backlight. In the TFT LCD display technology, in order to reduce the power consumption of the backlight light-emitting diode (Light Emitting Diode, LED), the content adaptive backlight control technology (Content Adaptive Backlight Control, CABC) is introduced, that is, the brightness of the backlight is adjusted according to the content of the image. In the existing TFT LCD display solution, when the user causes the LC...
