Touch display device and method, and washing machine

Abstract

The invention discloses touch display device and method, and a washing machine. The touch display device comprises a display screen, and a touch screen arranged on the display screen; the touch screen and the display screen are both connected with a controller, wherein the touch screen is divided into a display area and a key area; a key is arranged on the key area, and the key area is used for sensing an input signal and transmitting the input signal to the controller; the display screen is used for receiving a control signal and displaying the operation result through the display area; the display area and the key area are different in background color and font color; the display screen is a VA type LCD. The touch display device has the advantages that the mode in combination of the touch key and the display screen replaces the traditional mode in combination of the mechanical key and the display screen, so as to adapt to the habits of users in use; the display time of the display screen under electrifying can be greatly reduced, and the view angle is expanded; the contrast ratio of the display screen is up to more than 100: 1, which realizes high definition display; the view angle of the display screen is up to 180 degrees, which means full view angle and is convenient to user to view.

Description

technical field [0001] The invention relates to the field of relay control, in particular to a touch display device, a display method thereof, and a washing machine. Background technique [0002] At present, the display screen of the washing machine is usually manually operated and controlled by using mechanical buttons in conjunction with the display area. Specifically, the mechanical buttons are set at the lower end of the display screen, but the use of mechanical buttons is inconvenient to operate, and the input process is complicated and inaccurate. For example, for example, inputting a Chinese character requires multiple keystrokes, which is inconvenient to operate. [0003] And our current common pulsator liquid crystal display is a TN ordinary liquid crystal display with a contrast ratio of 10:1, which cannot meet the high-definition display requirements of some high-end users. In addition, the viewing angle range of common TN liquid crystal displays currently on the...

[0003] And our current common pulsator liquid crystal display is a TN common liquid crystal display with a contrast ratio of 10:1, which cannot meet the high-definition display requirements of some high-end users

In addition, the viewing angle range of ordinary TN liquid crystal displays on the market is about 60°, and the characters on the display screen cannot be viewed from a full viewing angle, and there are dead angles.

Longer display times when a voltage is applied to change the liquid crystal molecules to level to allow the backlight to pass through
