For example, in fig. 2, the driving chip 11 can control the LED elements 12 corresponding to the black portions to be turned off, and in contrast, in fig. 2, the driving chip 11 can control the LED elements 12 corresponding to the white portions to be turned on, so that the user-defined pattern can be displayed. For another example, in fig. 2, the driving chip 11 can control the LED elements 12 corresponding to the black portions to be on, and in contrast, in fig. 2, the driving chip 11 can control the LED elements 12 corresponding to the white portions to be off, so that the user-defined pattern can also be displayed.
In one embodiment, as shown in fig. 3, the plurality of LED elements 12 are divided into N lamp groups, and the number of LED elements 12 in each lamp group is M, where N and M are integers greater than 1. In one embodiment, the number N of lamp groups and the number M of LED elements 12 in each lamp group may not be equal; in other embodiments, the number N of lamp groups and the number M of LED elements 12 in each lamp group may be equal, and the embodiments of the present invention are illustrated in an equal relationship, but it should be understood that this is not a limitation. Illustratively, the number N of the plurality of lamp groups and the number M of LED elements 12 in each lamp group are both 24, i.e., 576 LED elements 12 are included.
In the present embodiment, the first poles of all LED elements 12 in a lamp group are connected to each other as a common control terminal, i.e. each lamp group has one common control terminal. In one embodiment, the cathodes of the LED elements 12 may be connected to each other as a common control terminal (i.e., a common cathode connection); in other embodiments, the anodes of the LED elements may be connected to each other as a common control terminal (i.e. a common anode connection), and the embodiments of the present invention are illustrated as a common cathode connection, but it should be understood that this is not a limitation.
In the present embodiment, the driving chip 11 includes X control pins (i.e., P pins in the figure), and X is an integer and at least equal to the larger of N and M, for example, if N > M, X is greater than or equal to N; conversely, if N < M, X is greater than M; if N = M, X is greater than N or M.

In the present example, the LED elements 12 are divided into groups, so that the scanning can be performed in a group manner, and thus the computation capability requirement of the driving chip 11 is reduced, and the cost is reduced; meanwhile, because the number of scanning times is greatly reduced, the lighting time of each LED element 12 is increased, and further, the screen brightness is improved, and the user experience is enhanced. For example, in the above example, by dividing 576 LED elements 12 into 24 groups, only 24 scans are needed, which greatly reduces the performance requirement of the driving chip 11, and at the same time, because the scanning times are greatly reduced, the lighting time of each LED element 12 in the same time is increased, and the screen brightness is brighter.

In one embodiment, the coffee cup may further include a thermistor RT, and the resistance of the thermistor RT may vary with the temperature of the liquid in the housing 10, that is, the resistance of the thermistor RT may represent the temperature of the water in the coffee cup, and the thermistor RT may be a negative temperature coefficient thermistor, for example, the resistance of which is inversely related to the temperature of the water in the cup.
In the present embodiment, as shown in fig. 5, one end of the thermistor RT is connected to the main control circuit 30, and the other end is connected to a predetermined voltage VCC, for example, 3.3V, through the resistor R. Based on this, the main control circuit 30 is further connected to the junction of the thermistor RT and the resistor R, and is configured to: when the temperature needs to be detected, an enable signal is output to receive the electric signal output by the connection, and the temperature of the liquid in the shell 20 is determined. Illustratively, when the device is activated, a low level signal (i.e., enable signal) may be periodically output to thermistor RT, for example, once every 100ms, which may reduce power consumption compared to a constant output, thereby enabling main control circuit 30 to receive the electrical signal output at the connection. For example, the liquid temperature may be determined according to the voltage amplitude of the electrical signal output from the connection and a preset mapping relationship. In an embodiment, the main control circuit 30 is further configured to control the dot matrix screen 10 to display the temperature of the liquid in the housing 20, that is, control the dot matrix screen 10 to display the temperature of the coffee, so that the coffee cup has a temperature display function.
