Embodiment Construction

[0030] Such as Figure 1A As shown, the liquid crystal display of the present invention includes a backlight source 10 , an LCD module 20 and a display driving circuit 30 . Wherein, the display driving circuit 30 includes a character / graphic driving circuit 31 , a background section driving circuit 32 , a backlight driving circuit 33 and a display mode selection and control unit 36 ​​. During the operation of the liquid crystal display, the display driving circuit 30 can control the display contents and display modes of the LCD module 20 according to needs and / or preset parameters, including the positive display mode, the negative display mode and the working state of the backlight.

[0031] Figure 1A The backlight 10 in the backlight may include one backlight, two backlights, or more backlights, and these backlights may be backlights of various colors, such as red, green, blue or other colors.

[0032] Figure 1A Among them, the display driving circuit 30 is also connected w...

Abstract

The invention relates to a displaying method of a liquid crystal display. The display comprises a liquid crystal display screen and backlight source of one color at least. The display screen is divided into a content area consisting of a plurality of character / figure sections and a background area. Under a first display mode, a character / figure part to be displayed in the content area of the display screen is driven as a first state, and the other part of the content area and the background area are driven as a second state; under a second display mode, the character / figure part to be displayed in the content area of the display screen is driven as the second state, and the other part of the content area and the background area are driven as the first state; wherein, the first state is lighttight state, and the second state is non-lighttight state; and when the part to be displayed in the content area is under the first state, the backlight source is selected and driven to work. The method can change positive and negative display forms according to an external command and change the color of backlight combined with the display form, thereby realizing the display in different forms and various colors with low cost.

Description

technical field [0001] The invention relates to a liquid crystal display, and more specifically, to a multi-mode display method of a liquid crystal display. Background technique [0002] In the prior art, a monochrome liquid crystal display generally adopts a positive display mode (also black characters on a white background) for display, and is generally equipped with only one backlight source. For example, most of the LCD clocks currently on the market are in the positive display mode. When the ambient light is weak, it is difficult to see the handwriting clearly, and the backlight needs to be turned on manually to see clearly. In addition, since there is only one color of the backlight, when the user needs to use different color backlights to indicate various prompt information, this requirement of the user cannot be met. [0003] Therefore, the monochrome liquid crystal display in the prior art has the defect of a single display mode, and cannot provide users with more ...
