specific Embodiment approach 1
[0024] A segment code liquid crystal screen analog pointer display device, such as figure 1 As shown, it includes a connector 1, a bottom case 2, a circuit board 3, a light guide cover 4, a segment code screen 5, a microprocessor 6, a drive circuit 7 and a power supply 8; The through hole is connected to the circuit board 3, the circuit board 3 is embedded in the bottom case 2, and the circuit board 3 is connected to the light guide cover 4; the light guide cover 4 is processed with a groove matching the segment code screen 5, The segment code screen 5 is embedded in the groove, the number of the segment code screen 5 is 2, and the segment code screen 5 is processed with some groups of analog pointers corresponding to the segment code screen numbers, and the analog pointer Each includes a liquid crystal, the analog pointer includes three parts, the first part and the third part have the same shape and size, the third part of the first group of analog pointers overlaps with the...
specific Embodiment approach 2
[0029] A method for continuously moving an analog pointer based on the segment code liquid crystal screen analog pointer display device described in Embodiment 1, comprising the following steps:
[0030] Step a, power supply 8 is connected to microprocessor 6;
[0031] Step b, the microprocessor 6 drives all 24 LED lamp beads on the circuit board 3 to light up through the drive circuit 7;
[0032] Step c, the brightness is irradiated onto the segment code screen 5 through the light guide cover 4;
[0033] Step d. At the same time, under the action of the power plant, the alignment direction of the liquid crystals in the analog pointer will be reversed, thus changing the light-repelling property;
[0034] Step e, the light under the analog pointer will shine out, and the analog pointer pointing to the first segment code screen number will be displayed;
[0035] Step f, when it is necessary to point to the second segment code screen number, the analog pointer pointing to the s...

Abstract
The invention relates to a segment code liquid crystal screen analog pointer display device and a method for analog pointer continuous movement, belonging to the technical field of automobile instrument display. The technical problem that the analog pointer in the display screen moves intermittently is solved. The connector is connected with a circuit board through a through hole machined on the bottom shell, the circuit board is embedded in the bottom shell, and the circuit board is connected with a light guide cover. The light guidemask is provided with a groove matched with the segment code screen, A segment code screen is embedded in the slot, the number of segment code screens is 2, A plurality of groups of analog pointers corresponding to the number of the segment code screen are machined on the segment code screen, the analog pointers include liquid crystals, the analog pointers include three parts, the first part is the same as the third part in shape and size, the third partof the first group of analog pointers coincides with the first part of the second group of analog pointers, and the analog pointers are arranged in sequence. The microprocessor is connected with a driving circuit and a power supply. The driving circuit is connected with a circuit board through a connector, and the power supply supplies power to the device. The method and the device realize continuous movement of the analog pointer.
Description
technical field [0001] The invention belongs to the technical field of automobile instrument display, in particular to a segment code liquid crystal screen analog pointer display device and a method for simulating pointer continuous movement. Background technique [0002] Segment code LCD has the advantages of extremely low requirements for the main control, simple driver programming, easy fixing and simple assembly, low price, high contrast and low power consumption, etc., and is widely used in household appliances, medical equipment and automotive instruments. However, when the analog pointer of the segment code LCD screen points from one number to another, it does not move continuously, but intermittently, which affects the display effect. Contents of the invention [0003] The present invention overcomes the deficiencies of the above-mentioned prior art, and provides a segment code liquid crystal screen analog pointer display device and a method for continuously moving...
