Description

Technical Field

[0001] The utility model relates to the technical field of display screens, and in particular to a display device for multi-color icons. Background Art

[0002] At present, most of the consumer products on the market involve the display of different colors. They are realized by using TFT color display screens or by means of pigment silk screen printing. In the fields of home appliances, gifts, etc., icon-like patterns are generally displayed. Since only some icons are displayed, the system hardware and configuration that drive the display device can be designed to be low, and a low-cost system solution can be adopted. When selecting a TFT color display screen, because the pattern is required to be larger than the pride, the required resolution is very large, the system hardware resources are relatively high, and the cost is relatively expensive. In particular, when the display pattern is required to be large and the number is small, the hardware requirements are higher, but the actual application resource requirements are relatively small, resulting in increased costs and waste of resources. Therefore, it is necessary to develop a display device that can display color content icons without occupying too many system resources. Utility Model Content

[0030] Embodiment 1

[0031] A display device of multi-color icons includes an LCD, a driving chip and an LED backlight. The LED backlight is composed of an R LED, a G LED and a B LED. The power input terminals A of the R LED, the G LED and the B LED are electrically connected to an external power supply. The positive electrodes of the R LED, the G LED and the B LED are connected together to form a common anode connection mode. The negative electrodes of the R LED, the G LED and the B LED are electrically connected to switches Q1, Q2 and Q3 through resistors R1, R2 and R3 respectively. The common anode connection mode is adopted to simplify the circuit design and wiring. The positive electrodes are connected together to reduce the number of connections on the circuit board, reduce the complexity and failure rate of the circuit, and improve the reliability of the entire system. The common anode connection mode reduces the lines of the positive electrode connection, so that space on the circuit board can be saved. This is particularly important for some space-constrained devices, such as mobile devices or embedded systems. The simplified circuit design and the reduced number of lines can reduce the manufacturing cost. This is particularly important for large-scale production, because the reduction in cost can increase the competitiveness of the product. The common anode connection mode can improve the stability of the LED drive. Since the positive poles are connected together, the current and voltage distribution of the LED are more uniform, which is conducive to ensuring the normal operation of the LED and extending the life of the LED. The negative pole of the LED is electrically connected to the switch through a resistor, so that the power-on and power-off states of the LED can be achieved by controlling the switch. Such a design makes the control of the LED more flexible, and the brightness and working state of the LED can be adjusted at any time according to needs. The negative pole of the R LED is electrically connected to the driver chip through the resistor R1 and the switch Q1 in turn, the negative pole of the G LED is electrically connected to the driver chip through the resistor R2 and the switch Q2 in turn, and the negative pole of the B LED is electrically connected to the driver chip through the resistor R3 and the switch Q3 in turn. The negative pole of each LED is electrically connected to the driver chip through the resistor and the switch, which makes it possible to finely control the brightness and state of each LED. By adjusting the resistor and the switch state, each LED can be independently controlled, thereby achieving the mixing and adjustment of the light. By controlling the state of the switch, the power on and off of the LED can be achieved, thereby realizing the dimming function of the light. This energy-saving dimming design can not only reduce energy consumption and extend the service life of the LED, but also adjust the light brightness as needed to improve the user experience. By limiting the current with a resistor, the working current of the LED can be stabilized to prevent the LED from being damaged due to excessive current. This design can improve the stability of the LED, extend the service life of the LED, and reduce the maintenance and replacement costs of the LED. The negative electrode of the LED is electrically connected to the driver chip through a resistor and a switch, making the control of the LED more flexible.By adjusting the parameters of the resistor and the switch, the brightness, color temperature, flickering frequency and other parameters of the LED can be adjusted to meet the needs of different scenarios. The LED backlight is electrically connected to the LCD through the driver chip, and the LCD covers the top of the LED backlight. The driver chip is connected and drives the LCD through COM&SEG. The driver chip synchronously controls the LCD icon display and controls the power-on and power-off states of RLED, G LED and B LED, so that the light of R LED, G LED and B LED can be transmitted through the lit LCD to display the color.

This technology can ensure the clarity and stability of icon display, while reducing energy consumption and extending the service life of the LCD.

[0036] Energy saving and environmental protection: LED as a backlight source has low energy consumption, and by controlling the power-on and power-off states of LED, energy consumption can be further reduced. This meets the needs of modern society for energy saving and environmental protection, and is also conducive to reducing the impact on the environment.
