Description
Technical Field
The invention relates to the technical field of information display, in particular to a pen-section type liquid crystal screen for a small-sized measuring instrument.
Background
Measurement is the process of converting the spatial information into numbers. Digital measuring instruments are mostly used at present, and measured data information is displayed through numbers on a screen. And the carrier is needed for displaying the numbers, and compared with a dot matrix screen, the pen-segment type liquid crystal screen is more cost-saving and reliable. In the field of measurement technology, pen-segment liquid crystal screens, such as display screens of small-sized measuring instruments such as laser range finders and mu finders, are often visible. In addition, the pen segment type liquid crystal panel is widely used for an LCD panel for display of an electronic watch, a calculator, a digital multimeter, and the like. At present, the most used is a Chinese character 'ri' shaped segment type liquid crystal screen (namely a Chinese character 'qi' shaped segment type liquid crystal screen which is called as a seven-segment '8' shaped segment type liquid crystal screen and is named as the Chinese character 'ri' for convenience in expression), the structure is simple, and the number of 0-9 can be displayed.
However, there are two important problems, firstly, when the number 1 is displayed, the right side of the "day" character is usually lighted up vertically, sometimes the number is close to the right side of the character, which causes misreading, and especially the rigor of the measurement field is affected, for example, as shown in fig. 2, the number 13 is close to the right side, and in the case of long distance or poor eyesight, the number is easy to read as 8; secondly, when the number 1 is displayed, the display is closer to the edge, and a large piece is left at the left side of the 1, so that the display is not beautiful and elegant.
Disclosure of Invention
The invention aims to solve the problem of reducing misreading caused by the connection of the right digit of a Chinese character 'ri' shaped pen-type liquid crystal display screen with the right digit when the Chinese character 'ri' shaped pen-type liquid crystal display screen displays the digit 1.
A pen-section type liquid crystal screen for a small-sized measuring instrument is a pen-section type liquid crystal screen in a shape of Chinese character 'ri', and is characterized in that a horizontal line on the Chinese character 'ri' is divided into a left section and a right section which are respectively called as a left section and a right section in a simplified mode, each section at least comprises one pixel, and when the pixel displays a number 1, only the right section on the upper right side and the right side of the Chinese character 'ri' are lighted up.
The method has the advantages that as shown in fig. 3, the upper right segment enables the discrimination of the number 1 and other numbers to be higher, and the number is not connected with the right number to cause misreading; in addition, the upper right section enables the number 1 to be visually and integrally deviated to the left, so that the left space is effectively utilized, and the unattractive feeling of being too close to the edge is reduced to a certain extent; meanwhile, "/" makes the displayed number 1 similar to the common bold number, a small hook is arranged on each 1, and the 1 is thickened when displayed on the pen-section type liquid crystal screen, so that the pen-section type liquid crystal screen is quite attractive; finally, because the upper right section is horizontal, when the character 'ri' is italic, the included angle between the upper right section and the right vertical is equal to less than 90 degrees, and the displayed number 1 is more similar to the common bold number and more beautiful; a section is divided from the upper edge of the Chinese character 'ri' to display the number 1, so that the upper edge and the lower edge are reasonably utilized, and a new diode is prevented from being added.
When other numbers are displayed, the upper left section and the upper right section are simultaneously lightened or not lightened, and the displayed numbers are the same as the Chinese character 'ri' shaped pen section type liquid crystal screen.
The display method has the advantages that the upper edge and the upper edge of the Chinese character 'ri' can be displayed together as a section, and the display of other numbers is not influenced.
The liquid crystal display is an eight-segment pen-segment liquid crystal display formed by cutting off the upper edge of a horizontal line on the basis of seven segments of Chinese character 'ri' pen-segment liquid crystal displays.
The beneficial effects are that, the number of stages is few, and easy equipment, control.
Each segment consists of 1 pixel.
The beneficial effects are that, every section comprises 1 pixel, simple structure, stability.
The length of the upper right segment does not exceed 1/2 of the upper cross.
The beneficial effects are that the length of the upper right section is shorter, the difference between the displayed numbers 1 and 7 is increased, and simultaneously 1 is more beautiful
The boundary of the upper left section and the upper right section is in a shape of '/'.
The display device has the advantages that the left section of the upper right section has an oblique angle, and the upper side of the display 7 is horizontally oriented, so that the display 1 is obviously different from the display 7 and is not easy to be confused.
The included angle between the '/' and the upper transverse is less than 45 degrees.
The beneficial effect is that the oblique angle of the left section of the upper right section is further reduced, so that the displayed 1 is more different from the displayed 7 and can not be confused.
The lower side of the Chinese character 'ri' is transversely divided into a left section and a right section which are respectively called as a lower left section and a lower right section for short, when the number 1 is displayed, the lower right section is also lightened, and the lower left section is not lightened.
The digital display device has the advantages that the footing is added under the displayed number 1, the digital display device is similar to the common bold number display, is easier to identify and more attractive, is more different from other numbers, and cannot be connected with the right number to cause misreading.
When other numbers are displayed, the lower left section and the lower right section are simultaneously lightened or not lightened, and the displayed numbers are the same as the Chinese character 'ri' shaped pen section type liquid crystal screen.
The display method has the advantages that the lower horizontal edge of the Chinese character 'ri' is divided into sections to display the number 1, the lower horizontal edge is reasonably utilized, new diodes are prevented from being added, meanwhile, the lower horizontal edges of the Chinese character 'ri' can be combined to be displayed as a section, and display of other numbers is not influenced.
The lower right segment has a length no greater than 1/2 of the lower lateral length.
The beneficial effect is that the length of the lower right section is basically consistent with the length of the '/', so that the appearance is more attractive.
In addition, it should be noted that the segment-type liquid crystal display is very suitable for a measuring instrument, but can also be used in other fields where the segment-type liquid crystal display is suitable, and all of which belong to the protection scope of the present invention.
