Change Background of QLCDNumber with PyQt5 to an image - python-3.x

Question

I currently have a program which changes the color of the background of the QLCDumber widget when a certain value is displayed on the lcd number, is it possible for instead of a color being the background when a certain value is reached an image appears in the background, such as a smiley face?
Here is the relevant snippet of my code responsible for the change in color.
def OnValueFound(self, value):
self.ui.lcdNumber.display(value)
if 100 < value < 300:
self.ui.lcdNumber.setStyleSheet("""QLCDNumber {background-color: green; color: black;}""")
else:
self.ui.lcdNumber.setStyleSheet("""QLCDNumber {background-color:red; color: black;}""")
so instead of say the background color changing to another color it changes to an image?
I hope this makes sense.

I do not know if I understood you correctly. Try it border-image: url(E:/_Qt/img/heart.png);
import sys
from random import randint
from PyQt5.QtWidgets import QApplication, QMainWindow
from PyQt5.QtCore import QTimer
from ui import Ui_MainWindow
class Form(QMainWindow):
def __init__(self):
super().__init__()
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
self.i = 0
self.voltageMin = 180
self.voltageMax = 180
self.ui.lcdNumberCur.display(self.i)
self.ui.lcdNumberCur.setStyleSheet("""QLCDNumber {
background-color: yellow;
}""")
self.ui.pushButton.clicked.connect(self.startTimer)
self.timer = QTimer(self)
self.timer.setInterval(1000)
self.timer.timeout.connect(self.updateData)
self.show()
def startTimer(self):
if self.ui.pushButton.text() == "Start Timer":
self.timer.start(1000)
self.ui.pushButton.setText("Stop Timer")
else:
self.ui.pushButton.setText("Start Timer")
self.timer.stop()
def updateData(self):
voltage = randint(80, 350) # <--- insert your average voltage here
self.ui.lcdNumberCur.display(voltage)
if voltage > self.voltageMax:
self.voltageMax = voltage
self.ui.lcdNumberMax.display(self.voltageMax)
if self.voltageMax > 300:
self.ui.lcdNumberMax.setStyleSheet("""QLCDNumber {
/* background-color: red; */
border-image: url(E:/_Qt/img/heart.png);
color: white; }""")
else:
self.ui.lcdNumberMax.setStyleSheet("""QLCDNumber
{ background-color: green;
color: yellow;
}""")
elif voltage < self.voltageMin:
self.voltageMin = voltage
self.ui.lcdNumberMin.display(self.voltageMin)
if self.voltageMin < 90:
self.ui.lcdNumberMin.setStyleSheet("""QLCDNumber {
background-color: red;
color: white; }""")
else:
self.ui.lcdNumberMin.setStyleSheet("""QLCDNumber
{ background-color: green;
color: yellow;
}""")
if __name__ == '__main__':
app = QApplication(sys.argv)
frm = Form()
sys.exit(app.exec_())
